  • Background custom button animation using WPF

    - by ajtp
    Hi, I am using Resources dictionaries to customize my controls and apply them as themes to my WPF application so I have implemented one for the button control. A code snippet for my custom Button.xaml is (its namespace is MyWPFApp.Themes): <ResourceDictionary ...> ... <LinearGradientBrush x:Key="NormalBackground" EndPoint="0,1" StartPoint="0,0"> <GradientStop Color="sc#1.000000, 0.250141, 0.333404, 0.884413" Offset="0"/> <GradientStop Color="#ccffffff" Offset="1"/> </LinearGradientBrush> <LinearGradientBrush x:Key="OverBackground" EndPoint="0,1" StartPoint="0,0"> <GradientStop Color="#da5e69" Offset="0"/> <GradientStop Color="#d12e27" Offset="1"/> </LinearGradientBrush> <LinearGradientBrush x:Key="ClickBackground" EndPoint="0,1" StartPoint="0,0"> <GradientStop Color="#d22828" Offset="1"/> <GradientStop Color="#b00000" Offset="0"/> </LinearGradientBrush> ... <Style TargetType="{x:Type Button}"> ... <Setter Property="Background" Value="{StaticResource NormalBackground}"/> ... </Style> </ResourceDictionary> and I apply it by doing the following from my main Application.xaml: <Application ...> <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Themes/Button.xaml"/> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> </Application> What I try to do is to change background color, for example, from White to Lime for 6 seconds by doing this from one of my pages, MyPage1.xaml, using StoryBoard: <Page x:Class="MyWPFApp.Pages.MyPage1" ...> <Page.Resources> ... <Storyboard x:Key="sbBtnResetHC" Storyboard.TargetName="BtnResetHC" Storyboard.TargetProperty="(Background). (SolidColorBrush.Color)"> <ColorAnimation From="Pink" To="Green" By="Blue" Duration="0:0:6" RepeatBehavior="3x" AutoReverse="True" /> </Storyboard> ... </Page.Resources> ... <Button x:Name="BtnResetHC" Click="BtnResetHC_Click" Width="90" Visibility="Collapsed" /> ... </Page> and from code behind MyPage1.xaml.cs I start animation by doing this: Storyboard sb = (Storyboard)FindResource("sbBtnResetHC"); sb.Begin(); when the button is visible, but it doesn't work for me. Any ideas what's wrong? Maybe another possibility, as I want the animation starts on button visible is to do a trigger for the button over Visibility property, Is it a better solution? Thanks a lot!

  • WPF Issues with Control Layout

    - by Brett Powell
    I am making an application that connects to our billing software using its API, and I am running into a few issues getting the layout working properly. I want to make it so that when one of the expanders is minimized, the other window fills the gap, and when it is expanded again the other expander goes back to where it was. Right now when the arrow is clicked on one, there is just an empty gap. I used a DockPanel as the parent which I assumed would automatically do this, but it isn't working. Second question, is there a way to make these areas resizable? I don't want to try and get too frisky with allowing the user to undock the menus (don't even know if that is possible with just straight WPF) but it would be nice if they could change the width/height of them. Also, just a newbie question to C#, but what is the equivalent of a C++ header file? It looks like you just use .cs files, but I am not sure. I want to extract all of my functions that pull the data from the billing software and put them into a different file to clean up the code. Here is my XAML... <Window x:Class="WpfApplication3.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Billing Management" Height="550" Width="754" xmlns:shared="http://schemas.actiprosoftware.com/winfx/xaml/shared" WindowStartupLocation="CenterScreen" WindowStyle="ThreeDBorderWindow"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="22" /> <RowDefinition /> </Grid.RowDefinitions> <Menu Height="22" Name="menu1" Margin="0" HorizontalAlignment="Stretch" VerticalAlignment="Top" HorizontalContentAlignment="Left" IsEnabled="True" IsMainMenu="True"> <MenuItem Header="_File"> <MenuItem Header="_Open" /> <MenuItem Header="_Close" /> <Separator/> <MenuItem Header="_Exit" /> </MenuItem> </Menu> <TabControl Name="tabControl1" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" BorderThickness="1" Padding="0" TabStripPlacement="Bottom" UseLayoutRounding="False" FlowDirection="LeftToRight" Grid.Row="1"> <TabItem Header="Main" Name="tabItem1" Margin="0"> <DockPanel Name="dockPanel1" LastChildFill="True"> <ListBox Height="100" Name="listBox3" DockPanel.Dock="Top" /> <ListBox Name="listBox4" Width="200" DockPanel.Dock="Right" /> <DockPanel Height="Auto" Name="dockPanel2" Width="Auto" VerticalAlignment="Stretch" LastChildFill="True"> <shared:AnimatedExpander Header="Staff Online" Width="200" Name="expanderStaffOnline" IsExpanded="True" Height="194" BorderThickness="0" DockPanel.Dock="Top" VerticalContentAlignment="Stretch"> <ListBox Name="listboxStaffOnline" Width="Auto" Height="Auto" Margin="0" VerticalAlignment="Stretch" Loaded="listboxStaffOnline_Loaded" /> </shared:AnimatedExpander> <shared:AnimatedExpander Header="Test Menu 2" Height="Auto" Name="animatedExpander1" BorderThickness="1" Margin="0,0,0,0" IsExpanded="True" VerticalContentAlignment="Stretch"> <ListBox Height="Auto" HorizontalAlignment="Stretch" Name="listBox6" VerticalAlignment="Stretch" Margin="0" BorderThickness="1" /> </shared:AnimatedExpander> </DockPanel> <ListBox Height="100" Name="listboxAdminLogs" DockPanel.Dock="Bottom" Loaded="listboxAdminLogs_Loaded" /> <ListBox Name="listBox5" /> </DockPanel> </TabItem> <TabItem Header="Support" Name="tabItem2" Margin="0"> </TabItem> <TabItem Header="Clients" /> <TabItem Header="Billing" /> <TabItem Header="Orders" /> </TabControl> </Grid> </Window>

  • WPF MVVM TreeView item source losing context after command

    - by user3955716
    I have a treeview which contains files, every view model holds an item source which is an ObservableCollection with files items: public ObservableCollection<CMItemFileNode> SubItemNode On each item i have context menu options (Delete, Execute..). If i move from one viewModel to another the ObservableCollection of files updated correctly and presented correctly but, when i perform a context menu command like delete file item, the command execute good but when i move to another view model (which holds SubItemNode ObservableCollection of is own) after the command executed the WPF still thinks i'm in the last view model i was in and not the one i'm really on. Very important to mention is that when i update to .net 4.5 (which unfortunantly i can't do) everything is ok and the ObservableCollection addresses the correct view model. Here is the treeView: <TreeView x:Name="Files" Margin="0,5,5,0" Grid.Row="6" Grid.Column="2" ItemsSource="{Binding SubItemNode}" HorizontalAlignment="Stretch" HorizontalContentAlignment="Stretch" VerticalAlignment="Stretch" Height="300" Grid.RowSpan="6" Width="300" dd:DragDrop.IsDragSource="True" dd:DragDrop.IsDropTarget="True" dd:DragDrop.DropHandler="{Binding}" dd:DragDrop.UseDefaultDragAdorner="True"> <TreeView.Resources> <Style TargetType="{x:Type TreeView}"> <Setter Property="local:CMTreeViewFilesBehavior.IsTreeViewFilesBehavior" Value="True"/> </Style> <Style TargetType="{x:Type TreeViewItem}"> <Setter Property="IsSelected" Value="{Binding IsSelected}" /> <Setter Property="local:CMTreeViewFilesItemBehavior.IsTreeViewFilesItemBehavior" Value="True"/> </Style> <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" /> <SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Black" /> </TreeView.Resources> <TreeView.ContextMenu> <ContextMenu> <MenuItem Header="View File" Command="{Binding ExecuteFileCommand}" /> <Separator /> <MenuItem Header="Delete all" Command="{Binding DeleteAllFilesCommand}" /> <MenuItem Header="Delete selected" Command="{Binding DeleteSelectedFilesCommand}" /> </ContextMenu> </TreeView.ContextMenu> <TreeView.ItemTemplate> <HierarchicalDataTemplate ItemsSource="{Binding SubItemNode}" > <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="*"/> </Grid.ColumnDefinitions> <Image Grid.Column="0" Margin="2" Width="32" Height="18" Source="{Binding Path=Icon}" HorizontalAlignment="Left" VerticalAlignment="Center" /> <TextBlock Text="{Binding Path=Name}" Grid.Column="1" Margin="2" VerticalAlignment="Center" Foreground="{Binding Path=Status, Converter={StaticResource ItemFileStatusToColor}}" FontWeight="{Binding Path=IsSelected, Converter={StaticResource BoolToFontWidth}}"/> </Grid> </HierarchicalDataTemplate> </TreeView.ItemTemplate> </TreeView> Am I doing somthing wrong? and why in .net 4.5 it works well ?

  • Simple Navigation In Windows Phone 7

    - by PeterTweed
    Take the Slalom Challenge at www.slalomchallenge.com! When moving to the mobile platform all applications need to be able to provide different views.  Navigating around views in Windows Phone 7 is a very easy thing to do.  This post will introduce you to the simplest technique for navigation in Windows Phone 7 apps. Steps: 1.     Create a new Windows Phone Application project. 2.     In the MainPage.xaml file copy the following xaml into the ContentGrid Grid:             <StackPanel Orientation="Vertical" VerticalAlignment="Center"  >                 <TextBox Name="ValueTextBox" Width="200" ></TextBox>                 <Button Width="200" Height="30" Content="Next Page" Click="Button_Click"></Button>             </StackPanel> This gives a text box for the user to enter text and a button to navigate to the next page. 3.     Copy the following event handler code to the MainPage.xaml.cs file:         private void Button_Click(object sender, RoutedEventArgs e)         {             NavigationService.Navigate(new Uri( string.Format("/SecondPage.xaml?val={0}", ValueTextBox.Text), UriKind.Relative));         }   The event handler uses the NavigationService.Navigate() function.  This is what makes the navigation to another page happen.  The function takes a Uri parameter with the name of the page to navigate to and the indication that it is a relative Uri to the current page.  Note also the querystring is formatted with the value entered in the ValueTextBox control – in a similar manner to a standard web querystring. 4.     Add a new Windows Phone Portrait Page to the project named SecondPage.xaml. 5.     Paste the following XAML in the ContentGrid Grid in SecondPage.xaml:             <Button Name="GoBackButton" Width="200" Height="30" Content="Go Back" Click="Button_Click"></Button>   This provides a button to navigate back to the first page. 6.     Copy the following event handler code to the SecondPage.xaml.cs file:         private void Button_Click(object sender, RoutedEventArgs e)         {             NavigationService.GoBack();         } This tells the application to go back to the previously displayed page. 7.     Add the following code to the constructor in SecondPage.xaml.cs:             this.Loaded += new RoutedEventHandler(SecondPage_Loaded); 8.     Add the following loaded event handler to the SecondPage.xaml.cs file:         void SecondPage_Loaded(object sender, RoutedEventArgs e)         {             if (NavigationContext.QueryString["val"].Length > 0)                 MessageBox.Show(NavigationContext.QueryString["val"], "Data Passed", MessageBoxButton.OK);             else                 MessageBox.Show("{Empty}!", "Data Passed", MessageBoxButton.OK);         }   This code pops up a message box displaying either the text entered on the first page or the message “{Empty}!” if no text was entered. 9.     Run the application, enter some text in the text box and click on the next page button to see the application in action:   Congratulations!  You have created a new Windows Phone 7 application with page navigation.

  • WPF Custom Buttons below ListBox Items

    - by Ryan
    WPF Experts - I am trying to add buttons below my custom listbox and also have the scroll bar go to the bottom of the control. Only the items should move and not the buttons. I was hoping for some guidance on the best way to achieve this. I was thinking the ItemsPanelTemplate needed to be modified but was not certain. Thanks My code is below <!-- List Item Selected --> <LinearGradientBrush x:Key="GotFocusStyle" EndPoint="0.5,1" StartPoint="0.5,0"> <LinearGradientBrush.GradientStops> <GradientStop Color="Black" Offset="0.501"/> <GradientStop Color="#FF091F34"/> <GradientStop Color="#FF002F5C" Offset="0.5"/> </LinearGradientBrush.GradientStops> </LinearGradientBrush> <!-- List Item Hover --> <LinearGradientBrush x:Key="MouseOverFocusStyle" StartPoint="0,0" EndPoint="0,1"> <LinearGradientBrush.GradientStops> <GradientStop Color="#FF013B73" Offset="0.501"/> <GradientStop Color="#FF091F34"/> <GradientStop Color="#FF014A8F" Offset="0.5"/> <GradientStop Color="#FF003363" Offset="1"/> </LinearGradientBrush.GradientStops> </LinearGradientBrush> <!-- List Item Selected --> <LinearGradientBrush x:Key="LostFocusStyle" EndPoint="0.5,1" StartPoint="0.5,0"> <LinearGradientBrush.RelativeTransform> <TransformGroup> <ScaleTransform CenterX="0.5" CenterY="0.5"/> <SkewTransform CenterX="0.5" CenterY="0.5"/> <RotateTransform CenterX="0.5" CenterY="0.5"/> <TranslateTransform/> </TransformGroup> </LinearGradientBrush.RelativeTransform> <GradientStop Color="#FF091F34" Offset="1"/> <GradientStop Color="#FF002F5C" Offset="0.4"/> </LinearGradientBrush> <!-- List Item Highlight --> <SolidColorBrush x:Key="ListItemHighlight" Color="#FFE38E27" /> <!-- List Item UnHighlight --> <SolidColorBrush x:Key="ListItemUnHighlight" Color="#FF6FB8FD" /> <Style TargetType="ListBoxItem"> <EventSetter Event="GotFocus" Handler="ListItem_GotFocus"></EventSetter> <EventSetter Event="LostFocus" Handler="ListItem_LostFocus"></EventSetter> </Style> <DataTemplate x:Key="CustomListData" DataType="{x:Type ListBoxItem}"> <Border BorderBrush="Black" BorderThickness="1" Margin="-2,0,0,-1"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListBoxItem}}, Path=ActualWidth}" /> </Grid.ColumnDefinitions> <Label VerticalContentAlignment="Center" BorderThickness="0" BorderBrush="Transparent" Foreground="{StaticResource ListItemUnHighlight}" FontSize="24" Tag="{Binding .}" Grid.Column="0" MinHeight="55" Cursor="Hand" FontFamily="Arial" FocusVisualStyle="{x:Null}" KeyboardNavigation.TabNavigation="None" Background="{StaticResource LostFocusStyle}" MouseMove="ListItem_MouseOver" > <Label.ContextMenu> <ContextMenu Name="editMenu"> <MenuItem Header="Edit"/> </ContextMenu> </Label.ContextMenu> <TextBlock Text="{Binding .}" Margin="15,0,40,0" TextWrapping="Wrap"></TextBlock> </Label> <Image Tag="{Binding .}" Source="{Binding}" Margin="260,0,0,0" Grid.Column="1" Stretch="None" Width="16" Height="22" HorizontalAlignment="Center" VerticalAlignment="Center" /> </Grid> </Border> </DataTemplate> </Window.Resources> <Window.DataContext> <ObjectDataProvider ObjectType="{x:Type local:ImageLoader}" MethodName="LoadImages" /> </Window.DataContext> <ListBox ItemsSource="{Binding}" Width="320" Background="#FF021422" BorderBrush="#FF1C4B79" > <ListBox.Resources> <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}">Transparent</SolidColorBrush> <Style TargetType="{x:Type ListBox}"> <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Disabled" /> <Setter Property="ItemTemplate" Value="{StaticResource CustomListData }" /> </Style> </ListBox.Resources> </ListBox>

  • WPF ComboBox Binding breaks when using ControlTemplate

    - by Mitch
    I have a WPF ComboBox that has been working fine until I recently created a ControlTemplate for it to enable me to change the color of the DropDown arrow. The ComboBox still works correctly except the Bound Text value now just shows the name of the Business Object rather than the bound value. I guess that binding like Text="{Binding Path=CaseDateRange}" no longer works when using a ControlTemplate, yet the ItemsSource binding on the dropdown seems to still work fine. Can anyone offer some help with how I need to change my binding when using a ControlTemplate. The code for the ControlTemplate and ComboBox is as follows <ControlTemplate x:Key="ComboBoxControlTemplate1" TargetType="{x:Type ComboBox}"> <Grid x:Name="MainGrid" SnapsToDevicePixels="True"> <Grid.ColumnDefinitions> <ColumnDefinition Width="*"/> <ColumnDefinition MinWidth="{DynamicResource {x:Static SystemParameters.VerticalScrollBarWidthKey}}" Width="0"/> </Grid.ColumnDefinitions> <Popup x:Name="PART_Popup" AllowsTransparency="True" Grid.ColumnSpan="2" IsOpen="{Binding IsDropDownOpen, RelativeSource={RelativeSource TemplatedParent}}" Margin="1" PopupAnimation="{DynamicResource {x:Static SystemParameters.ComboBoxPopupAnimationKey}}" Placement="Bottom" OpacityMask="#FF2A3D64"> <Microsoft_Windows_Themes:SystemDropShadowChrome x:Name="Shdw" Color="Transparent" MaxHeight="{TemplateBinding MaxDropDownHeight}" MinWidth="{Binding ActualWidth, ElementName=MainGrid}"> <Border x:Name="DropDownBorder" BorderBrush="White" BorderThickness="1" CornerRadius="3" Background="{DynamicResource DialogDarkBlue}"> <ScrollViewer x:Name="DropDownScrollViewer" > <Grid RenderOptions.ClearTypeHint="Enabled"> <Canvas HorizontalAlignment="Left" Height="0" VerticalAlignment="Top" Width="0"> <Rectangle x:Name="OpaqueRect" Fill="{Binding Background, ElementName=DropDownBorder}" Height="{Binding ActualHeight, ElementName=DropDownBorder}" Width="{Binding ActualWidth, ElementName=DropDownBorder}"/> </Canvas> <ItemsPresenter x:Name="ItemsPresenter" KeyboardNavigation.DirectionalNavigation="Contained" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/> </Grid> </ScrollViewer> </Border> </Microsoft_Windows_Themes:SystemDropShadowChrome> </Popup> <ToggleButton BorderBrush="{TemplateBinding BorderBrush}" Background="{TemplateBinding Background}" Grid.ColumnSpan="2" IsChecked="{Binding IsDropDownOpen, Mode=TwoWay, RelativeSource={RelativeSource TemplatedParent}}" Foreground="White"> <ToggleButton.Style> <Style TargetType="{x:Type ToggleButton}"> <Setter Property="OverridesDefaultStyle" Value="True"/> <Setter Property="IsTabStop" Value="False"/> <Setter Property="Focusable" Value="False"/> <Setter Property="ClickMode" Value="Press"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type ToggleButton}"> <Microsoft_Windows_Themes:ButtonChrome x:Name="Chrome" BorderBrush="{TemplateBinding BorderBrush}" Background="{TemplateBinding Background}" RenderMouseOver="{TemplateBinding IsMouseOver}" RenderPressed="{TemplateBinding IsPressed}" SnapsToDevicePixels="True"> <Grid HorizontalAlignment="Right" Width="{DynamicResource {x:Static SystemParameters.VerticalScrollBarWidthKey}}"> <Path x:Name="Arrow" Data="M0,0L3.5,4 7,0z" Fill="White" HorizontalAlignment="Center" Margin="3,1,0,0" VerticalAlignment="Center"/> </Grid> </Microsoft_Windows_Themes:ButtonChrome> <ControlTemplate.Triggers> <Trigger Property="IsChecked" Value="True"> <Setter Property="RenderPressed" TargetName="Chrome" Value="True"/> </Trigger> <Trigger Property="IsEnabled" Value="False"> <Setter Property="Fill" TargetName="Arrow" Value="#FFAFAFAF"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> </ToggleButton.Style> </ToggleButton> <ContentPresenter ContentTemplate="{TemplateBinding SelectionBoxItemTemplate}" Content="{TemplateBinding SelectionBoxItem}" ContentStringFormat="{TemplateBinding SelectionBoxItemStringFormat}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" IsHitTestVisible="False" Margin="{TemplateBinding Padding}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/> </Grid> <ControlTemplate.Triggers> <Trigger Property="HasDropShadow" SourceName="PART_Popup" Value="True"> <Setter Property="Margin" TargetName="Shdw" Value="0,0,5,5"/> <Setter Property="Color" TargetName="Shdw" Value="#71000000"/> </Trigger> <Trigger Property="HasItems" Value="False"> <Setter Property="Height" TargetName="DropDownBorder" Value="95"/> </Trigger> <Trigger Property="IsEnabled" Value="False"> <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/> <Setter Property="Background" Value="#FFF4F4F4"/> </Trigger> <Trigger Property="IsGrouping" Value="True"> <Setter Property="ScrollViewer.CanContentScroll" Value="False"/> </Trigger> <Trigger Property="CanContentScroll" SourceName="DropDownScrollViewer" Value="False"> <Setter Property="Canvas.Top" TargetName="OpaqueRect" Value="{Binding VerticalOffset, ElementName=DropDownScrollViewer}"/> <Setter Property="Canvas.Left" TargetName="OpaqueRect" Value="{Binding HorizontalOffset, ElementName=DropDownScrollViewer}"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> And the ComboBox is <ComboBox x:Name="cboSelectedCase" Text="{Binding Path=CaseDateRange}" DisplayMemberPath="CaseDateRange" SelectedValuePath="CaseID" Template="{DynamicResource ComboBoxControlTemplate1}" />

  • Trouble updating my datagrid in WPF

    - by wrigley06
    As the title indicates, I'm having trouble updating a datagrid in WPF. Basically what I'm trying to accomplish is a datagrid, that is connected to a SQL Server database, that updates automatically once a user enters information into a few textboxes and clicks a submit button. You'll notice that I have a command that joins two tables. The data from the Quote_Data table will be inserted by a different user at a later time. For now my only concern is getting the information from the textboxes and into the General_Info table, and from there into my datagrid. The code, which I'll include below compiles fine, but when I hit the submit button, nothing happens. This is the first application I've ever built working with a SQL Database so many of these concepts are new to me, which is why you'll probably look at my code and wonder what is he thinking. public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); } public DataSet mds; // main data set (mds) private void Window_Loaded_1(object sender, RoutedEventArgs e) { try { string connectionString = Sqtm.Properties.Settings.Default.SqtmDbConnectionString; using (SqlConnection connection = new SqlConnection(connectionString)) { connection.Open(); //Merging tables General_Info and Quote_Data SqlCommand cmd = new SqlCommand("SELECT General_Info.Quote_ID, General_Info.Open_Quote, General_Info.Customer_Name," + "General_Info.OEM_Name, General_Info.Qty, General_Info.Quote_Num, General_Info.Fab_Drawing_Num, " + "General_Info.Rfq_Num, General_Info.Rev_Num, Quote_Data.MOA, Quote_Data.MOQ, " + "Quote_Data.Markup, Quote_Data.FOB, Quote_Data.Shipping_Method, Quote_Data.Freight, " + "Quote_Data.Vendor_Price, Unit_Price, Quote_Data.Difference, Quote_Data.Vendor_NRE_ET, " + "Quote_Data.NRE, Quote_Data.ET, Quote_Data.STI_NET, Quote_Data.Mfg_Time, Quote_Data.Delivery_Time, " + "Quote_Data.Mfg_Name, Quote_Data.Mfg_Location " + "FROM General_Info INNER JOIN dbo.Quote_Data ON General_Info.Quote_ID = Quote_Data.Quote_ID", connection); SqlDataAdapter da = new SqlDataAdapter(cmd); DataTable dt = new DataTable(); da.Fill(dt); MainGrid.ItemsSource = dt.DefaultView; mds = new DataSet(); da.Fill(mds, "General_Info"); MainGrid.DataContext = mds.Tables["General_Info"]; } } catch (Exception ex) { MessageBox.Show(ex.Message); } // renaming column names from the database so they are easier to read in the datagrid MainGrid.Columns[0].Header = "#"; MainGrid.Columns[1].Header = "Date"; MainGrid.Columns[2].Header = "Customer"; MainGrid.Columns[3].Header = "OEM"; MainGrid.Columns[4].Header = "Qty"; MainGrid.Columns[5].Header = "Quote Number"; MainGrid.Columns[6].Header = "Fab Drawing Num"; MainGrid.Columns[7].Header = "RFQ Number"; MainGrid.Columns[8].Header = "Rev Number"; MainGrid.Columns[9].Header = "MOA"; MainGrid.Columns[10].Header = "MOQ"; MainGrid.Columns[11].Header = "Markup"; MainGrid.Columns[12].Header = "FOB"; MainGrid.Columns[13].Header = "Shipping"; MainGrid.Columns[14].Header = "Freight"; MainGrid.Columns[15].Header = "Vendor Price"; MainGrid.Columns[16].Header = "Unit Price"; MainGrid.Columns[17].Header = "Difference"; MainGrid.Columns[18].Header = "Vendor NRE/ET"; MainGrid.Columns[19].Header = "NRE"; MainGrid.Columns[20].Header = "ET"; MainGrid.Columns[21].Header = "STINET"; MainGrid.Columns[22].Header = "Mfg.

  • Adding data (not only text) to a multi column ListView (WPF)

    - by user811804
    I am working on a WPF application in C# (.NET 4.0) where I have a ListView with a GridView that has two columns. I dynamically want to add rows (in code). My dilemma is that only the first column will have regular text added to it. The second column will have an object that includes a multi column Grid with TextBlocks. (see link http://imageshack.us/photo/my-images/803/listview.png/) If I do what you would normally do when you want to enter text in all columns (ie. DisplayMemberBinding) all I get in the second column is the text "System.Windows.Grid", which obviously isn't what I want. For reference if I just try to add the Grid object (with the TextBlocks) with the code listView1.Items.Add(grid1) (not using DisplayMemberBinding) the object gets added to the second column only (with the first column being blank) and not how it normally works with text where the same text ends up in all columns. I hope my question is detailed enough and any help with this would be much appreciated. EDIT: I have tried the following code, howeever every time I click the button to add a new row every single row gets updated with the same datatemplate. (ie. the second column always shows the same data on every row.) xaml: <Window x:Class="TEST.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Name="AAA" Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded"> <Grid Name="grid1"> <Grid.ColumnDefinitions> <ColumnDefinition Width="374*" /> <ColumnDefinition Width="129*" /> </Grid.ColumnDefinitions> <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="21,12,0,0" Name="button1" VerticalAlignment="Top" Width="75" Grid.Column="1" Click="button1_Click" /> </Grid> code: public partial class MainWindow : Window { ListView listView1 = new ListView(); GridViewColumn viewCol2 = new GridViewColumn(); public MainWindow() { InitializeComponent(); Style style = new Style(typeof(ListViewItem)); style.Setters.Add(new Setter(ListViewItem.HorizontalContentAlignmentProperty, HorizontalAlignment.Stretch)); listView1.ItemContainerStyle = style; GridView gridView1 = new GridView(); listView1.View = gridView1; GridViewColumn viewCol1 = new GridViewColumn(); viewCol1.Header = "Option"; gridView1.Columns.Add(viewCol1); viewCol2.Header = "Value"; gridView1.Columns.Add(viewCol2); grid1.Children.Add(listView1); viewCol1.DisplayMemberBinding = new Binding("Option"); } private void Window_Loaded(object sender, RoutedEventArgs e) { } private void button1_Click(object sender, RoutedEventArgs e) { DataTemplate dataTemplate = new DataTemplate(); FrameworkElementFactory spFactory = new FrameworkElementFactory(typeof(Grid)); Random random = new Random(); int cols = random.Next(1, 6); int full = 100; for (int i = 0; i < cols; i++) { FrameworkElementFactory col1 = new FrameworkElementFactory(typeof(ColumnDefinition)); int partWidth = random.Next(0, full); full -= partWidth; col1.SetValue(ColumnDefinition.WidthProperty, new GridLength(partWidth, GridUnitType.Star)); spFactory.AppendChild(col1); } if (full > 0) { FrameworkElementFactory col1 = new FrameworkElementFactory(typeof(ColumnDefinition)); col1.SetValue(ColumnDefinition.WidthProperty, new GridLength(full, GridUnitType.Star)); spFactory.AppendChild(col1); } for (int i = 0; i < cols; i++) { FrameworkElementFactory text1 = new FrameworkElementFactory(typeof(TextBlock)); SolidColorBrush sb1 = new SolidColorBrush(); switch (i) { case 0: sb1.Color = Colors.Blue; break; case 1: sb1.Color = Colors.Red; break; case 2: sb1.Color = Colors.Yellow; break; case 3: sb1.Color = Colors.Green; break; case 4: sb1.Color = Colors.Purple; break; case 5: sb1.Color = Colors.Pink; break; case 6: sb1.Color = Colors.Brown; break; } text1.SetValue(TextBlock.BackgroundProperty, sb1); text1.SetValue(Grid.ColumnProperty, i); spFactory.AppendChild(text1); } if (full > 0) { FrameworkElementFactory text1 = new FrameworkElementFactory(typeof(TextBlock)); SolidColorBrush sb1 = new SolidColorBrush(Colors.Black); text1.SetValue(TextBlock.BackgroundProperty, sb1); text1.SetValue(Grid.ColumnProperty, cols); spFactory.AppendChild(text1); } dataTemplate.VisualTree = spFactory; viewCol2.CellTemplate = dataTemplate; int rows = listView1.Items.Count + 1; listView1.Items.Add(new { Option = "Row " + rows }); } }

  • WPF Some styles not applied on DataTemplate controls

    - by Martin
    Hi, I am trying to learn something about WPF and I am quite amazed by its flexibility. However, I have hit a problem with Styles and DataTemplates, which is little bit confusing. I have defined below test page to play around a bit with styles etc and found that the Styles defined in <Page.Resources> for Border and TextBlock are not applied in the DataTemplate, but Style for ProgressBar defined in exactly the same way is applied. Source code (I just use Kaxaml and XamlPadX to view the result) <Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Page.Resources> <Style TargetType="{x:Type Border}"> <Setter Property="Background" Value="SkyBlue"/> <Setter Property="BorderBrush" Value="Black"/> <Setter Property="BorderThickness" Value="2"/> <Setter Property="CornerRadius" Value="5"/> </Style> <Style TargetType="{x:Type TextBlock}"> <Setter Property="FontWeight" Value="Bold"/> </Style> <Style TargetType="{x:Type ProgressBar}"> <Setter Property="Height" Value="10"/> <Setter Property="Width" Value="100"/> <Setter Property="Foreground" Value="Red"/> </Style> <XmlDataProvider x:Key="TestData" XPath="/TestData"> <x:XData> <TestData xmlns=""> <TestElement> <Name>Item 1</Name> <Value>25</Value> </TestElement> <TestElement> <Name>Item 2</Name> <Value>50</Value> </TestElement> </TestData> </x:XData> </XmlDataProvider> <HierarchicalDataTemplate DataType="TestElement"> <Border Height="45" Width="120" Margin="5,5"> <StackPanel Orientation="Vertical" Margin="5,5" VerticalAlignment="Center" HorizontalAlignment="Center"> <TextBlock HorizontalAlignment="Center" Text="{Binding XPath=Name}"/> <ProgressBar Value="{Binding XPath=Value}"/> </StackPanel> </Border> </HierarchicalDataTemplate> </Page.Resources> <StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Center"> <StackPanel Orientation="Vertical" VerticalAlignment="Center"> <Border Height="45" Width="120" Margin="5,5"> <StackPanel Orientation="Vertical" VerticalAlignment="Center" HorizontalAlignment="Center"> <TextBlock HorizontalAlignment="Center" Text="Item 1"/> <ProgressBar Value="25"/> </StackPanel> </Border> <Border Height="45" Width="120" Margin="5,5"> <StackPanel Orientation="Vertical" VerticalAlignment="Center" HorizontalAlignment="Center"> <TextBlock HorizontalAlignment="Center" Text="Item 2"/> <ProgressBar Value="50"/> </StackPanel> </Border> </StackPanel> <ListBox Margin="10,10" Width="140" ItemsSource="{Binding Source={StaticResource TestData}, XPath=TestElement}"/> </StackPanel> </Page> I suspect it has something to do with default styles etc, but more puzzling is why some Styles are applied and some not. I cannot find an easy explanation for above anywhere and thus would like to ask if someone would be kind enough to explain this behaviour in lamens' terms with possible links to technical description, i.e. to MSDN or so. Thanks in advance for you support!

  • How to automate detection of out of order tab navigation in Qt dialogs?

    - by WilliamKF
    Typically, a dialog wishes to have tab navigation proceed in an orderly fashion through a dialog that roughly corresponds to the order of reading a book. When new fields are added to a dialog by engineers on a team, the new widgets can often not be inserted in tab correct order. Can anyone think of a way to automate the detection of out of tab navigation order widgets within a dialog?

  • Bindable richTextBox still hanging in memory {WPF, Caliburn.Micro}

    - by Paul
    Hi, I use in WFP Caliburn.Micro Framework. I need bindable richTextbox for Document property. I found many ways how do it bindable richTextBox. But I have one problem. From parent window I open child window. Child window consist bindable richTextBox user control. After I close child window and use memory profiler view class with bindabelrichTextBox control and view model class is still hanging in memory. - this cause memory leaks. If I use richTextBox from .NET Framework or richTextBox from Extended WPF Toolkit it doesn’t cause this memory leak problem. I can’t identified problem in bindable richTextBox class. Here is ist class for bindable richTextBox: Base class can be from .NET or Extended toolkit. /// <summary> /// Represents a bindable rich editing control which operates on System.Windows.Documents.FlowDocument /// objects. /// </summary> public class BindableRichTextBox : RichTextBox { /// <summary> /// Identifies the <see cref="Document"/> dependency property. /// </summary> public static readonly DependencyProperty DocumentProperty = DependencyProperty.Register("Document", typeof(FlowDocument), typeof(BindableRichTextBox)); /// <summary> /// Initializes a new instance of the <see cref="BindableRichTextBox"/> class. /// </summary> public BindableRichTextBox() : base() { } /// <summary> /// Initializes a new instance of the <see cref="BindableRichTextBox"/> class. /// </summary> /// <param title="document">A <see cref="T:System.Windows.Documents.FlowDocument"></see> to be added as the initial contents of the new <see cref="T:System.Windows.Controls.BindableRichTextBox"></see>.</param> public BindableRichTextBox(FlowDocument document) : base(document) { } /// <summary> /// Raises the <see cref="E:System.Windows.FrameworkElement.Initialized"></see> event.

  • Is WPF a good choice for developing line of business user interfaces?

    - by Randy Minder
    We're debating whether our future Windows UI development should be WinForms or WPF. How have some of you made this decision? Most of our applications are LOB applications, and I'm not sure I see a clear and overwhelming benefit to WPF for these types of applications. However, my knowledge of WPF is limited. I'm also a little concerned that WPF will be in vogue for another couple years and then Microsoft will get tired of it and push something else on us. I guess one argument against this is the fact that Visual Studio 2010 is a WPF application. Thanks.

  • Project Navigation and File Nesting in ASP.NET MVC Projects

    - by Rick Strahl
    More and more I’m finding myself getting lost in the files in some of my larger Web projects. There’s so much freaking content to deal with – HTML Views, several derived CSS pages, page level CSS, script libraries, application wide scripts and page specific script files etc. etc. Thankfully I use Resharper and the Ctrl-T Go to Anything which autocompletes you to any file, type, member rapidly. Awesome except when I forget – or when I’m not quite sure of the name of what I’m looking for. Project navigation is still important. Sometimes while working on a project I seem to have 30 or more files open and trying to locate another new file to open in the solution often ends up being a mental exercise – “where did I put that thing?” It’s those little hesitations that tend to get in the way of workflow frequently. To make things worse most NuGet packages for client side frameworks and scripts, dump stuff into folders that I generally don’t use. I’ve never been a fan of the ‘Content’ folder in MVC which is just an empty layer that doesn’t serve much of a purpose. It’s usually the first thing I nuke in every MVC project. To me the project root is where the actual content for a site goes – is there really a need to add another folder to force another path into every resource you use? It’s ugly and also inefficient as it adds additional bytes to every resource link you embed into a page. Alternatives I’ve been playing around with different folder layouts recently and found that moving my cheese around has actually made project navigation much easier. In this post I show a couple of things I’ve found useful and maybe you find some of these useful as well or at least get some ideas what can be changed to provide better project flow. The first thing I’ve been doing is add a root Code folder and putting all server code into that. I’m a big fan of treating the Web project root folder as my Web root folder so all content comes from the root without unneeded nesting like the Content folder. By moving all server code out of the root tree (except for Code) the root tree becomes a lot cleaner immediately as you remove Controllers, App_Start, Models etc. and move them underneath Code. Yes this adds another folder level for server code, but it leaves only code related things in one place that’s easier to jump back and forth in. Additionally I find myself doing a lot less with server side code these days, more with client side code so I want the server code separated from that. The root folder itself then serves as the root content folder. Specifically I have the Views folder below it, as well as the Css and Scripts folders which serve to hold only common libraries and global CSS and Scripts code. These days of building SPA style application, I also tend to have an App folder there where I keep my application specific JavaScript files, as well as HTML View templates for client SPA apps like Angular. Here’s an example of what this looks like in a relatively small project: The goal is to keep things that are related together, so I don’t end up jumping around so much in the solution to get to specific project items. The Code folder may irk some of you and hark back to the days of the App_Code folder in non Web-Application projects, but these days I find myself messing with a lot less server side code and much more with client side files – HTML, CSS and JavaScript. Generally I work on a single controller at a time – once that’s open it’s open that’s typically the only server code I work with regularily. Business logic lives in another project altogether, so other than the controller and maybe ViewModels there’s not a lot of code being accessed in the Code folder. So throwing that off the root and isolating seems like an easy win. Nesting Page specific content In a lot of my existing applications that are pure server side MVC application perhaps with some JavaScript associated with them , I tend to have page level javascript and css files. For these types of pages I actually prefer the local files stored in the same folder as the parent view. So typically I have a .css and .js files with the same name as the view in the same folder. This looks something like this: In order for this to work you have to also make a configuration change inside of the /Views/web.config file, as the Views folder is blocked with the BlockViewHandler that prohibits access to content from that folder. It’s easy to fix by changing the path from * to *.cshtml or *.vbhtml so that view retrieval is blocked:<system.webServer> <handlers> <remove name="BlockViewHandler"/> <add name="BlockViewHandler" path="*.cshtml" verb="*" preCondition="integratedMode" type="System.Web.HttpNotFoundHandler" /> </handlers> </system.webServer> With this in place, from inside of your Views you can then reference those same resources like this:<link href="~/Views/Admin/QuizPrognosisItems.css" rel="stylesheet" /> and<script src="~/Views/Admin/QuizPrognosisItems.js"></script> which works fine. JavaScript and CSS files in the Views folder deploy just like the .cshtml files do and can be referenced from this folder as well. Making this happen is not really as straightforward as it should be with just Visual Studio unfortunately, as there’s no easy way to get the file nesting from the VS IDE directly (you have to modify the .csproj file). However, Mads Kristensen has a nice Visual Studio Add-in that provides file nesting via a short cut menu option. Using this you can select each of the ‘child’ files and then nest them under a parent file. In the case above I select the .js and .css files and nest them underneath the .cshtml view. I was even toying with the idea of throwing the controller.cs files into the Views folder, but that’s maybe going a little too far :-) It would work however as Visual Studio doesn’t publish .cs files and the compiler doesn’t care where the files live. There are lots of options and if you think that would make life easier it’s another option to help group related things together. Are there any downside to this? Possibly – if you’re using automated minification/packaging tools like ASP.NET Bundling or Grunt/Gulp with Uglify, it becomes a little harder to group script and css files for minification as you may end up looking in multiple folders instead of a single folder. But – again that’s a one time configuration step that’s easily handled and much less intrusive then constantly having to search for files in your project. Client Side Folders The particular project shown above in the screen shots above is a traditional server side ASP.NET MVC application with most content rendered into server side Razor pages. There’s a fair amount of client side stuff happening on these pages as well – specifically several of these pages are self contained single page Angular applications that deal with 1 or maybe 2 separate views and the layout I’ve shown above really focuses on the server side aspect where there are Razor views with related script and css resources. For applications that are more client centric and have a lot more script and HTML template based content I tend to use the same layout for the server components, but the client side code can often be broken out differently. In SPA type applications I tend to follow the App folder approach where all the application pieces that make the SPA applications end up below the App folder. Here’s what that looks like for me – here this is an AngularJs project: In this case the App folder holds both the application specific js files, and the partial HTML views that get loaded into this single SPA page application. In this particular Angular SPA application that has controllers linked to particular partial views, I prefer to keep the script files that are associated with the views – Angular Js Controllers in this case – with the actual partials. Again I like the proximity of the view with the main code associated with the view, because 90% of the UI application code that gets written is handled between these two files. This approach works well, but only if controllers are fairly closely aligned with the partials. If you have many smaller sub-controllers or lots of directives where the alignment between views and code is more segmented this approach starts falling apart and you’ll probably be better off with separate folders in js folder. Following Angular conventions you’d have controllers/directives/services etc. folders. Please note that I’m not saying any of these ways are right or wrong  – this is just what has worked for me and why! Skipping Project Navigation altogether with Resharper I’ve talked a bit about project navigation in the project tree, which is a common way to navigate and which we all use at least some of the time, but if you use a tool like Resharper – which has Ctrl-T to jump to anything, you can quickly navigate with a shortcut key and autocomplete search. Here’s what Resharper’s jump to anything looks like: Resharper’s Goto Anything box lets you type and quick search over files, classes and members of the entire solution which is a very fast and powerful way to find what you’re looking for in your project, by passing the solution explorer altogether. As long as you remember to use (which I sometimes don’t) and you know what you’re looking for it’s by far the quickest way to find things in a project. It’s a shame that this sort of a simple search interface isn’t part of the native Visual Studio IDE. Work how you like to work Ultimately it all comes down to workflow and how you like to work, and what makes *you* more productive. Following pre-defined patterns is great for consistency, as long as they don’t get in the way you work. A lot of the default folder structures in Visual Studio for ASP.NET MVC were defined when things were done differently. These days we’re dealing with a lot more diverse project content than when ASP.NET MVC was originally introduced and project organization definitely is something that can get in the way if it doesn’t fit your workflow. So take a look and see what works well and what might benefit from organizing files differently. As so many things with ASP.NET, as things evolve and tend to get more complex I’ve found that I end up fighting some of the conventions. The good news is that you don’t have to follow the conventions and you have the freedom to do just about anything that works for you. Even though what I’ve shown here diverges from conventions, I don’t think anybody would stumble over these relatively minor changes and not immediately figure out where things live, even in larger projects. But nevertheless think long and hard before breaking those conventions – if there isn’t a good reason to break them or the changes don’t provide improved workflow then it’s not worth it. Break the rules, but only if there’s a quantifiable benefit. You may not agree with how I’ve chosen to divert from the standard project structures in this article, but maybe it gives you some ideas of how you can mix things up to make your existing project flow a little nicer and make it easier to navigate for your environment. © Rick Strahl, West Wind Technologies, 2005-2014Posted in ASP.NET  MVC   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  • Strange WPF ListBox Behavior

    - by uncle-harvey
    I’m trying to bind a List of items to a listbox in WPF. The items are grouped by one value and each group is to be housed in an expander. Everything works fine when I don’t use any custom styles. However, when I use custom styles (which work properly with non-grouped items and as independent controls) the binding doesn’t display any items. Below is the code I’m executing. Any ideas why the items won’t show up in the Expander? Test.xaml: <Window x:Class="Glossy.Test" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Test" Height="300" Width="300">

  • Google Rolls Out a New and Compact Navigation Bar

    - by Jason Fitzpatrick
    Earlier this spring Google introduced the black navigation bar; now they’ve updated the bar to take up less space and be more useful. Although the black bar is useful in-so-far as it gives you quick access to Google services (useful, of course, only if you use those services) the new navigation bar–seen in the video above–includes an improved layout. Rather than use the bar space to spread out links which the user may or may not use the service links are now tucked into a mouse-over menu accessed by hovering on the Google logo. The majority of the space previously just taken up by links and the black bar itself is now a a search box. If you don’t already see the new interface, look for it to appear in your Google account within the next few days. Hit up the link below to read the official announcement.

  • MemoryStream and BitmapSource

    - by Vinjamuri
    I have a MemoryStream of 10K which was created from a bitmap of 2MB and compressed using JPEG. Since MemoryStream can’t directly be placed in System.Windows.Controls.Image for the GUI, I am using the following intermediate code to convert this back to BitmapImage and eventually System.Windows.Controls.Image. System.Windows.Controls.Image image = new System.Windows.Controls.Image(); BitmapImage imageSource = new BitmapImage(); s.SlideInformation.Thumbnail.Seek(0, SeekOrigin.Begin); imageSource.BeginInit(); imageSource.CacheOption = BitmapCacheOption.OnDemand; imageSource.CreateOptions = BitmapCreateOptions.DelayCreation; imageSource.StreamSource = s.SlideInformation.Thumbnail; imageSource.EndInit(); imageSource.Freeze(); image.Source = imageSource; ret = image.Source; My question is, when I store this in BitmapImage, the memory allocation is taking around 2MB. Is this expected? Is there any way to reduce the memory? I have around 300 thumbnails and this converstion takes around 600MB, which is very high. Appreciate your help!

  • How To Raise Property Changed events on a Dependency Property?

    - by Muad'Dib
    OK, so I have this control with two properties. One of these is a DependencyProperty, the other is an "alias" to the first one. What I need to be able to do is raise the PropertyChanged event for the second one (the alias) when the first one is changed. NOTE: I am using DependencyObjects, not INotifyPropertyChanged (tried that, didn't work because my control is a sub-classed ListView) something like this..... protected override void OnPropertyChanged(DependencyPropertyChangedEventArgs e) { base.OnPropertyChanged(e); if (e.Property == MyFirstProperty) { RaiseAnEvent( MySecondProperty ); /// what is the code that would go here? } } If I were using an INotify I could do like this... public string SecondProperty { get { return this.m_IconPath; } } public string IconPath { get { return this.m_IconPath; } set { if (this.m_IconPath != value) { this.m_IconPath = value; this.SendPropertyChanged("IconPath"); this.SendPropertyChanged("SecondProperty"); } } } where I can raise PropertyChanged events on multiple properties from one setter. I need to be able to do the same thing, only using DependencyProperties.
