  • Assemble an image browser side with JavaScript or Flash?

    - by Kris Walker
    Would it be possible to assemble an image on the browser by 'concatenating' other downloaded images together? The use case is this. The page will display 36 different tiles (small images). The user should be able to arrange those tiles into a 6 x 6 grid and save the resulting grid to disk as an image. The best solution would be to do it all in the browser without Flash. The next best solution would be to allow the user to create the grid in the browser with simple JavaScript drag and drop functionality and then send the coordinates to the server for image processing. The last solution would be to do it all in the browser with Flash. Is it even possible for Flash to create an image and then allow the user to save it from the browser? I am familiar with the Pixastic JavaScript library ( http://www.pixastic.com/ ), but it relies on getting image data to and from a canvas element which is not very well supported. What if I send the tile images to the browser as base64 encoded strings? Could I use JavaScript to create the 6 x 6 grid image? And if so, is there some way of allowing the user to get it onto disk without relying on the canvas element?

  • Borderless ImageButtons in WrapPanel

    - by Bill
    I am attempting to create a WrapPanel with seamless ImageButtons containing Artwork. I put together the following ContentTemplate in the hopes that it would provide the seamless look required; however a thin white-line remained around each of the buttons. Can anyone steer me in the right direction? <Button.ContentTemplate> <DataTemplate DataType="{x:Type local:ArtInfo}"> <Border Name="border" BorderThickness="0" BorderBrush="blue" Height="280" Width="250" Background="#262c40"> <StackPanel> <Grid> <Grid.Resources> <local:MyConverter x:Key="MyConverter"></local:MyConverter> <ObjectDataProvider x:Key="Properties.Settings" ObjectType="{x:Type lcl:Properties.Settings}" /> </Grid.Resources> <Image Name="ArtImage" Margin="10,15,0,0" Height="195" Width="195" VerticalAlignment="Top" > <Image.Source> <Binding Path="ArtImage"/> </Image.Source> </Image> </Grid> <TextBlock Text="{Binding Path=ArtClass}" Margin="10,-17,0,0" FontSize="11" Foreground="white" /> <TextBlock Text="{Binding Path=Student}" Margin="10,0,0,0" FontSize="11" Foreground="white" /> <TextBlock Text="1998" Margin="10,0,0,0" FontSize="11" Foreground="white" /> </StackPanel> </Border> </DataTemplate> </Button.ContentTemplate>

  • [Delphi] How would you refactor this code?

    - by Al C
    This hypothetical example illustrates several problems I can't seem to get past, even though I keep trying!! ... Suppose the original code is a long event handler, coded in the UI, triggered when a user clicks a cell in a grid. Expressed as pseudocode it's: if Condition1=true then begin //loop through every cell in row, //if aCell/headerCellValue>1 then //color aCell red end else if Condition2=true then begin //do some other calculation adding cell and headerCell values, and //if some other product>2 then //color the whole row green end else show an error message I look at this and say "Ah, refactor to the strategy pattern! The code will be easier to understand, easier to debug, and easier to later extend!" I get that. And I can easily break the code into multiple procedures. The problem is ultimately scope related. Assume the pseudocode makes extensive use of grid properties, values displayed in cells, maybe even built-in grid methods. How do you move all that to another unit, without referencing the grid component in the UI--which would break all the "rules" about loose coupling that make OOP valuable? ... I'm really looking forward to responses. Thanks, as always -- Al C.

  • Silverlight MVVM Confusion: Updating Image Based on State

    - by senfo
    I'm developing a Silverlight application and I'm trying to stick to the MVVM principals, but I'm running into some problems changing the source of an image based on the state of a property in the ViewModel. For all intents and purposes, you can think of the functionality I'm implementing as a play/pause button for an audio app. When in the "Play" mode, IsActive is true in the ViewModel and the "Pause.png" image on the button should be displayed. When paused, IsActive is false in the ViewModel and "Play.png" is displayed on the button. Naturally, there are two additional images to handle when the mouse hovers over the button. I thought I could use a Style Trigger, but apparently they're not supported in Silverlight. I've been reviewing a forum post with a question similar to mine where it's suggested to use the VisualStateManager. While this might help with changing the image for hover/normal states, the part missing (or I'm not understanding) is how this would work with a state set via the view model. The post seems to apply only to events rather than properties of the view model. Having said that, I also haven't successfully completed the normal/hover affects, either. Below is my Silverlight 4 XAML. It should also probably be noted I'm working with MVVM Light. <UserControl x:Class="Foo.Bar.MyUserControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity" mc:Ignorable="d" d:DesignHeight="100" d:DesignWidth="200"> <UserControl.Resources> <Style x:Key="MyButtonStyle" TargetType="Button"> <Setter Property="IsEnabled" Value="true"/> <Setter Property="IsTabStop" Value="true"/> <Setter Property="Background" Value="#FFA9A9A9"/> <Setter Property="Foreground" Value="#FF000000"/> <Setter Property="MinWidth" Value="5"/> <Setter Property="MinHeight" Value="5"/> <Setter Property="Margin" Value="0"/> <Setter Property="HorizontalAlignment" Value="Left" /> <Setter Property="HorizontalContentAlignment" Value="Center"/> <Setter Property="VerticalAlignment" Value="Top" /> <Setter Property="VerticalContentAlignment" Value="Center"/> <Setter Property="Cursor" Value="Hand"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Button"> <Grid> <Image Source="/Foo.Bar;component/Resources/Icons/Bar/Play.png"> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="Active"> <VisualState x:Name="MouseOver"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Source" Storyboard.TargetName="/Foo.Bar;component/Resources/Icons/Bar/Play_Hover.png" /> </Storyboard> </VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> </Image> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> </UserControl.Resources> <Grid x:Name="LayoutRoot" Background="White"> <Button Style="{StaticResource MyButtonStyle}" Command="{Binding ChangeStatus}" Height="30" Width="30" /> </Grid> </UserControl> What is the proper way to update images on buttons with the state determined by the view model? Update I changed my Button to a ToggleButton hoping I could use the Checked state to differentiate between play/pause. I practically have it, but I ran into one additional problem. I need to account for two states at the same time. For example, Checked Normal/Hover and Unchecked Normal/Hover. Following is my updated XAML: <UserControl x:Class="Foo.Bar.MyUserControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity" mc:Ignorable="d" d:DesignHeight="100" d:DesignWidth="200"> <UserControl.Resources> <Style x:Key="MyButtonStyle" TargetType="ToggleButton"> <Setter Property="IsEnabled" Value="true"/> <Setter Property="IsTabStop" Value="true"/> <Setter Property="Background" Value="#FFA9A9A9"/> <Setter Property="Foreground" Value="#FF000000"/> <Setter Property="MinWidth" Value="5"/> <Setter Property="MinHeight" Value="5"/> <Setter Property="Margin" Value="0"/> <Setter Property="HorizontalAlignment" Value="Left" /> <Setter Property="HorizontalContentAlignment" Value="Center"/> <Setter Property="VerticalAlignment" Value="Top" /> <Setter Property="VerticalContentAlignment" Value="Center"/> <Setter Property="Cursor" Value="Hand"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ToggleButton"> <Grid> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="CommonStates"> <VisualState x:Name="Normal"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="Pause"> <DiscreteObjectKeyFrame KeyTime="0"> <DiscreteObjectKeyFrame.Value> <Visibility>Collapsed</Visibility> </DiscreteObjectKeyFrame.Value> </DiscreteObjectKeyFrame> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> <VisualState x:Name="MouseOver"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="PlayHover"> <DiscreteObjectKeyFrame KeyTime="0"> <DiscreteObjectKeyFrame.Value> <Visibility>Visible</Visibility> </DiscreteObjectKeyFrame.Value> </DiscreteObjectKeyFrame> </ObjectAnimationUsingKeyFrames> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="Play"> <DiscreteObjectKeyFrame KeyTime="0"> <DiscreteObjectKeyFrame.Value> <Visibility>Collapsed</Visibility> </DiscreteObjectKeyFrame.Value> </DiscreteObjectKeyFrame> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> </VisualStateGroup> <VisualStateGroup x:Name="CheckStates"> <VisualState x:Name="Checked"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="Pause"> <DiscreteObjectKeyFrame KeyTime="0"> <DiscreteObjectKeyFrame.Value> <Visibility>Visible</Visibility> </DiscreteObjectKeyFrame.Value> </DiscreteObjectKeyFrame> </ObjectAnimationUsingKeyFrames> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="Play"> <DiscreteObjectKeyFrame KeyTime="0"> <DiscreteObjectKeyFrame.Value> <Visibility>Collapsed</Visibility> </DiscreteObjectKeyFrame.Value> </DiscreteObjectKeyFrame> </ObjectAnimationUsingKeyFrames> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="PlayHover"> <DiscreteObjectKeyFrame KeyTime="0"> <DiscreteObjectKeyFrame.Value> <Visibility>Collapsed</Visibility> </DiscreteObjectKeyFrame.Value> </DiscreteObjectKeyFrame> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> <VisualState x:Name="Unchecked" /> </VisualStateGroup> </VisualStateManager.VisualStateGroups> <Image x:Name="Play" Source="/Foo.Bar;component/Resources/Icons/Bar/Play.png" /> <Image x:Name="Pause" Source="/Foo.Bar;component/Resources/Icons/Bar/Pause.png" Visibility="Collapsed" /> <Image x:Name="PlayHover" Source="/Foo.Bar;component/Resources/Icons/Bar/Play_Hover.png" Visibility="Collapsed" /> <Image x:Name="PauseHover" Source="/Foo.Bar;component/Resources/Icons/Bar/Pause_Hover.png" Visibility="Collapsed" /> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> </UserControl.Resources> <Grid x:Name="LayoutRoot" Background="White"> <ToggleButton Style="{StaticResource MyButtonStyle}" IsChecked="{Binding IsPlaying}" Command="{Binding ChangeStatus}" Height="30" Width="30" /> </Grid> </UserControl>

  • How can I bind another DependencyProperty to the IsChecked Property of a CheckBox?

    - by speedmetal
    Here's an example of what I'm trying to accomplish: <Window x:Class="CheckBoxBinding.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <StackPanel> <CheckBox Name="myCheckBox">this</CheckBox> <Grid> <Grid.Resources> <Style TargetType="ListBox"> <Style.Triggers> <Trigger Property="{Binding ElementName=myCheckBox, Path=IsChecked}" Value="True"> <Setter Property="Background" Value="Red" /> </Trigger> </Style.Triggers> </Style> </Grid.Resources> <ListBox> <ListBoxItem>item</ListBoxItem> <ListBoxItem>another</ListBoxItem> </ListBox> </Grid> </StackPanel> </Window> When I try to run it, I get this XamlParseException: A 'Binding' cannot be set on the 'Property' property of type 'Trigger'. A 'Binding' can only be set on a DependencyProperty of a DependencyObject. So how can I bind a property on the ListBox to the IsChecked property of a CheckBox?

  • Set focus to a button in a new TabItem

    - by Jan
    I use a TabControl to display a list of items. The ItemView is a separate control I wrote. <TabControl SelectedItem="{Binding CurrentItem}" IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding ItemList}"> <TabControl.ContentTemplate> <DataTemplate> <ctrls:ItemView/> </DataTemplate> </TabControl.ContentTemplate> <TabControl.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding ShortItemDescription}"/> </DataTemplate> </TabControl.ItemTemplate> </TabControl> If the user presses a Button a new ViewModel is added to the list of ViewModels and the TabControl displays it as a new tab. After adding the new tab is selected. <Button Command="{Binding AddItemCommand}" Content="Add item"/> Inside of the new ViewModel is a button that needs to be focused each time a new tab is added. I have tried to use the FocusManager and the Initialized event in the ItemView but these are only called for the first time I add a new tab. <UserControl x:Class="ItemView" ... Initialized="ViewInitialized"> <Grid> ... <!-- Set focus to this button --> <Button Content="Search" Command="{Binding SearchCommand}" Name="SearchButton" Grid.Column="0" Grid.Row="0"/> </Grid> </UserControl> Any ideas?

  • Why might a silverlight ListBox on Windows Phone not allow me scroll all the way down to the bottom?

    - by Byron Sommardahl
    I have a ListBox in a grid that gets databound when the page loads... pretty straightforward. The problem I'm having is that, after the box is databound, I can scroll... but not all the way to the bottom of the list. It stops an item or two short and won't let me scroll anymore. Here's the listbox XAML: <Grid x:Name="ContentGrid" Grid.Row="2"> <ListBox x:Name="lbFeed" ItemsSource="{Binding Items}" SelectionChanged="lbFeed_SelectionChanged" VerticalAlignment="Top" Width="480"> <ListBox.ItemTemplate> <DataTemplate x:Key="MyDataTemplate"> <StackPanel Orientation="Vertical" Width="430"> <TextBlock Text="Some text" TextAlignment="Center" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </Grid> I can post more code, but I'm still getting my feet wet in XAML and I'm not sure what might be causing this. If you need more context, let me know and I'll add it here.

  • How can I bind a List as ItemSource to ListView in XAML?

    - by Jonas
    I'm learning WPF and would like to have a collection similar to a LinkedList, to where I can add and remove strings. And I want to have a ListView that listen to that collection with databinding. How can I do bind a simple list collection to a ListView in XAML?

  • Android How to get position of selected item from gridview without using onclicklistner, using ontouchlistner instead

    - by zonemikel
    I have a gridview, I need to do stuff on motioneven.action_down and do something for motioneven.action_up ... using onclicklistener is great but does not give me this needed functionality. Is there anyway to easily call the gridview and get its selected item in a ontouchlistener ? I've been having limited success with making my own implementation. Its hard to get the right x,y because if i call the child it gives me the x and y relative to the child so a button would be 0,0 to 48,48 but it does not tell you the actual location on the screen relative to the gridview or the screen itself. this is what i've been doing, its partially working so far. Grid.setOnTouchListener(new OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_DOWN) { int x = (int)event.getX(); int y = (int)event.getY(); int position = 0; int childCount = Grid.getChildCount(); Message msg = new Message(); Rect ButtonRect = new Rect(); Grid.getChildAt(0).getDrawingRect(ButtonRect); int InitialLeft = ButtonRect.left + 10; ButtonRect.offsetTo(InitialLeft, ButtonRect.top); // while(position < childCount){ if(ButtonRect.contains(x,y)){break;} if(ButtonRect.right + ButtonRect.width() > Grid.getWidth()) { ButtonRect.offsetTo(InitialLeft, ButtonRect.bottom);} position++; ButtonRect.offsetTo(ButtonRect.right, ButtonRect.top); } msg.what = position; msg.arg1 = ButtonRect.bottom; msg.arg2 = y; cHandler.sendMessage(msg); }// end if action up if (event.getAction() == MotionEvent.ACTION_UP) { } return false; } });

  • What corresponds to the Unity 'registration name' in the unity configuration section?

    - by unanswered
    When registering and resolving types in a Unity Container using code you can use 'Registration Names' to disambiguate your references that derive from an interface or base class hierarchy. The 'registration name' text would be provided as a parameter to the register and resolve methods: myContainer.RegisterType<IMyService, CustomerService>("Customers"); and MyServiceBase result = myContainer.Resolve<MyServiceBase>("Customers"); However when I register types in the configuration files I do not see where the 'registration name' can be assigned I register an Interface: <typeAlias alias="IEnlistmentNotification" type="System.Transactions.IEnlistmentNotification, System.Transactions, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" /> Then two types that I happen to know implement that interface: <typeAlias alias="PlaylistManager" type="Sample.Dailies.Grid.Workers.PlaylistManager, Sample.Dailies.Grid.Workers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" /> <typeAlias alias="FlexAleManager" type="Sample.Dailies.Grid.Workers.FlexAleManager, Sample.Dailies.Grid.Workers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" /> Then I provide mappings between the interface and the two types: <type type="IEnlistmentNotification" mapTo="FlexAleManager"><lifetime type="singleton"/></type> <type type="IEnlistmentNotification" mapTo="PlaylistManager"><lifetime type="singleton"/></type> That seems to correspond to this code: myContainer.RegisterType<IEnlistmentNotification, FlexAleManager>(); myContainer.RegisterType<IEnlistmentNotification, PlaylistManager>(); but clearly what I need is a disambiguating config entry that corresponds to this code: myContainer.RegisterType<IEnlistmentNotification, FlexAleManager>("Flex"); myContainer.RegisterType<IEnlistmentNotification, PlaylistManager>("Play"); Then when I get into my code I could do this: IEnlistmentNotification flex = myContainer.Resolve<IEnlistmentNotification>("Flex"); IEnlistmentNotification play = myContainer.Resolve<IEnlistmentNotification>("Play"); See what I mean?

  • WPF DataGridRow Template - how to achieve Selected event

    - by user1809972
    I would like to override the DataGridRow template depending on the datatype of object bound to the grid. If the type is label, it just shows a Label. Otehrwise, it shows the cells. Follwing is the xaml. <DataTrigger Binding="{Binding Path=IsLabel, UpdateSourceTrigger=PropertyChanged}" Value="True"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type DataGridRow}"> <Grid> <Label HorizontalAlignment="Center" Padding="3,3,3,3" FontWeight="Bold" Content="{Binding Id}"/> </Grid> </ControlTemplate> </Setter.Value> </Setter> </DataTrigger> The grid looks ok. But, when the Label is clicked, it doesnt raise the Selection changed event for the DataGridRow. How do I achieve this behaviour? This label should just behave as any other DataGridRow(with the default template). Thanks

  • WPF data-bound ComboBox only shows first item of ItemsSource list

    - by Mark
    Hi all, I'm sure I'm doing something stupid but for the life of me I can't think of right now. I have a ComboBox that is data-bound to a list of Layout objects. The list is initially empty but things are added over time. When the list is updated by the model the first time, this update reflects properly in the ComboBox. However, subsequent updates never show up in the ComboBox even though I can see that the list itself contains these items. Since the first update works, I know the data-binding is OK - so what am I doing wrong here? Here's the XAML (abridged): <Grid HorizontalAlignment="Stretch"> <ComboBox ItemsSource="{Binding Path=SavedLayouts, diagnostics:PresentationTraceSources.TraceLevel=High}" DisplayMemberPath="Name" SelectedValuePath="Name" SelectedItem="{Binding LoadLayout}" Height="25" Grid.Row="1" Grid.Column="0"></ComboBox> </Grid> And the related part of the model: public IList<Layout> SavedLayouts { get { return _layouts; } } public Layout SaveLayout( String data_ ) { Layout theLayout = new Layout( SaveLayoutName ); _layouts.Add( theLayout ); try { return theLayout; } finally { PropertyChangedEventHandler handler = PropertyChanged; if( handler != null ) { handler( this, new PropertyChangedEventArgs( "SavedLayouts" ) ); } } } And finally, the layout class (abridged): public class Layout { public String Name { get; private set; } } In the output window, I can see the update occurring: System.Windows.Data Warning: 91 : BindingExpression (hash=64564967): Got PropertyChanged event from TickerzModel (hash=43624632) System.Windows.Data Warning: 97 : BindingExpression (hash=64564967): GetValue at level 0 from TickerzModel (hash=43624632) using RuntimePropertyInfo(SavedLayouts): List`1 (hash=16951421 Count=11) System.Windows.Data Warning: 76 : BindingExpression (hash=64564967): TransferValue - got raw value List`1 (hash=16951421 Count=11) System.Windows.Data Warning: 85 : BindingExpression (hash=64564967): TransferValue - using final value List`1 (hash=16951421 Count=11) But I get do not get this 11th item in the ComboBox. Any ideas?

  • How to make a cell in a datagrid readonly based the content on another cell in SL4?

    - by Nair
    I have two columns, the second column depends on the content on the first column. By default, the second columns is readonly. When I enter some valid value, I want the second column to become editable. To achive this, I created a cell template and cell edit template on the second column where back ground and read only bound to the first column. On load, the first column is null so my second columns comes correctly as read only. Following is Cell Template for second column, where the background color is set by based on the first column. <DataTemplate> <Grid> <Border Background="{Binding FristColumn,Converter={StaticResource ColorConverter}}"/> <TextBlock Text="{Binding SecondColumn, Converter={StaticResource NumberFormatter}}" HorizontalAlignment="Stretch" VerticalAlignment="Center" Margin="0"/> </Grid> </DataTemplate> Following is cell edit template for second column to make it editable <DataTemplate> <Grid> <TextBox Text="{Binding SecondColumn, Mode=TwoWay, Converter={StaticResource NumberFormatter}}" Margin="0" HorizontalAlignment="Right" IsReadOnly="{Binding FirstColumn, Converter={StaticResource readOnlyConverter}, ConverterParameter=FirstColumn}" Background="{Binding Depend,Converter={StaticResource ColorConverter}, ConverterParameter=FirstColumn}" /> </Grid> </DataTemplate> With these two in place, when enter the valid value in the first column, I was expecting the second column color to change but it does not. But If I double click on the cell then it behaves properly based on the first cell. Is there some thing I am missing?

  • coordination transform issue in Silverlight

    - by George2
    Hello everyone, I am using Silverlight 3.0 + .Net 3.5 + VSTS 2008 + C# to develop silverlight application based on ASP.Net. I am very confused about what are the function of "TranslateTransform" and "RenderTransformOrigin" in the following code snippet? BTW: I roughly understand RenderTransformOrigin means move an UI element in x-axis and y-axis by some offset, is that correct? Move the whole UI element? <Grid Margin="-1,0,100,0" x:Name="controlsContainer" Height="35" RenderTransformOrigin="0.5,0.5" VerticalAlignment="Bottom"> <Grid.RenderTransform> <TransformGroup> <ScaleTransform/> <SkewTransform/> <RotateTransform/> <TranslateTransform Y="0"/> </TransformGroup> </Grid.RenderTransform> <Rectangle Margin="0,0,0,0" Height="35" VerticalAlignment="Top" Fill="#97000000" Stroke="#00000000" RenderTransformOrigin="0.5,0.5"/> <VideoPlayer:mediaControl Height="35" Margin="1,0,0,0" HorizontalAlignment="Stretch" VerticalAlignment="Top" x:Name="mediaControls" Visibility="Visible"/> </Grid> thanks in advance, George

  • How do I anchor an expander to right side of a ListBox?

    - by Scott
    The XAML code below works fine except I want the expander button to be between the listbox and the grid. If I set the ExpandDirection="Left" the button is between the listbox and the grid but the direction indicator on the button is confusing to users - it point to the right when expanded and it points to the left when it is not expanded. I want the direction indicator to work the way it does when ExpandDirection="Right" but I want the functionality of ExpandDirection="Left". <DockPanel> <Expander ExpandDirection="Right"> <ListBox> <ListBoxItem>Item One</ListBoxItem> <ListBoxItem>Item Two</ListBoxItem> <ListBoxItem>Item Three</ListBoxItem> <ListBoxItem>Item Four</ListBoxItem> <ListBoxItem>Item Five</ListBoxItem> </ListBox> </Expander> <Grid Background="AliceBlue"> <TextBlock > Other Content </TextBlock> </Grid> </DockPanel>

  • TypeError when using v 0.8.1 of FLOT library, but no error with v. 0.7

    - by DanielAttard
    I need some help to figure out why I am getting an error when trying to create a simple graph using the jQuery FLOT library. When I reference version 0.7 of the FLOT library, the page renders correctly: http://attardpropertytax.ca/flot07.html But when I switch to version 0.8.1 of the FLOT library, the page returns an error saying: Uncaught TypeError: Cannot read property 'left' of null http://attardpropertytax.ca/flot81.html The HTML is the same for both pages, so I cannot figure out why the new version 0.8.1 of FLOT returns an error, but the old version 0.7 does not. Any ideas? I somehow stumbled across a work-around that managed to fix my problem. I'm nut sure why, but I had to comment-out the following two sections of code from the v. 0.8.1 FLOT library: This was the first spot: // If the grid is visible, add its border width to the offset for (var a in plotOffset) { if(typeof(options.grid.borderWidth) == "object") { plotOffset[a] += showGrid ? options.grid.borderWidth[a] : 0; } else { plotOffset[a] += showGrid ? options.grid.borderWidth : 0; } } And this was the second spot: if (isNaN(v) || v < axis.min || v > axis.max // skip those lying on the axes if we got a border || (t == "full" && ((typeof bw == "object" && bw[axis.position] > 0) || bw > 0) && (v == axis.min || v == axis.max))) continue; I'm sure eventually @DNS will be taking a look at this question and maybe he will be able to help me understand what is going wrong with my code. Thanks.

  • WPF: How do I bind a Control to a formula composed of several dependency properties?

    - by Pablo
    Hi all, I'm working on Expression Blend and I'm currently designing a custom control which has a Grid with 5 rows inside, and also has two Dependency properties: "Value", and "Maximum". Three of the rows have fixed height, and what I'm trying to do is set the remaining rows height to "Value/Maximum" and "1-Value/Maximum" respectively. How do I go and do that? When I set the height to "Value" it seems to react, but when I go and set it to "Value/Maximum" it stops working. I'm still a bit new around WPF, so there must be another way to achieve what I'm intending, but after searching I couln't find my problem elsewhere. Code: <Grid x:Name="LayoutRoot" Width="Auto" Background="Transparent"> <Grid.RowDefinitions> <RowDefinition Height="32"/> <RowDefinition Height="{Binding Path=(Value/Maximum), ElementName=UserControl, Mode=Default}"/> <RowDefinition Height="16"/> <RowDefinition Height="{Binding Path=(1-Value/Maximum), ElementName=UserControl, Mode=Default}"/> <RowDefinition Height="32"/> </Grid.RowDefinitions> (...) By the way, Value is always a not negative double less than or equal to Maximum; so the result of the division will be number between 0.0 a 1.0. I want a "star" instead of "pixel" row height.

  • GridView edit problem If primary key is editable (design problem)

    - by Nassign
    I would like to ask about the design of table based on it's editability in a Grid View. Let me explain. For example, I have a table named ProductCustomerRel. Method 1 CustomerCode varchar PK ProductCode varchar PK StoreCode varchar PK Quantity int Note text So the combination of the CustomerCode, StoreCode and ProductCode must be unique. The record is displayed on a gridview. The requirement is that you can edit the customer, product and storecode but when the data is saved, the PK constraint must still persist. The problem here is it would be natural for a grid to be able to edit the 3 primary key, you can only achieve the update operation of the grid view by first deleting the row and then inserting the row with the updated data. An alternative to this is to just update the table and add a SeqNo, and just enforce the unique constraint of the 3 columns when inserting and updating in the grid view. Method 2 SeqNo int PK CustomerCode varchar ProductCode varchar StoreCode varchar Quantity int Note text My question is which of the two method is better? or is there another way to do this?

  • XAML PixelGrid to Prevent Blurry Text

    - by Bodekaer
    Hi, Just wanted to share a small Grid I created, which can help prevent blurry text etc. as it adjusts the margin of the Grid to ensure a pixel perfect position and size of the grid. Works great e.g. for inside StackPanels with auto height Labels/TextBlocks. Here is the code: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Media; namespace Controls { class PixelGrid : Grid { protected override void OnRenderSizeChanged(SizeChangedInfo sizeInfo) { // POSITION Vector position = VisualTreeHelper.GetOffset(this); double targetX = Math.Round(position.X, MidpointRounding.ToEven); double targetY = Math.Round(position.Y, MidpointRounding.ToEven); double marginLeft = targetX - position.X; double marginTop = targetY - position.Y; // SIZE double targetHeight = Math.Round(sizeInfo.NewSize.Height, MidpointRounding.ToEven); double targetWidth = Math.Round(sizeInfo.NewSize.Width, MidpointRounding.ToEven); double marginBottom = targetHeight - sizeInfo.NewSize.Height; double marginRight = targetWidth - sizeInfo.NewSize.Width; // Adjust margin to ensure pixel width this.Margin = new Thickness(marginLeft, marginTop, marginRight, marginBottom); base.OnRenderSizeChanged(sizeInfo); } } }

  • Strange behaviour of DataTable with DataGridView

    - by Paul
    Please explain me what is happening. I have created a WinForms .NET application which has DataGridView on a form and should update database when DataGridView inline editing is used. Form has SqlDataAdapter _da with four SqlCommands bound to it. DataGridView is bound directly to DataTable _names. Such a CellValueChanged handler: private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e) { _da.Update(_names); } does not update database state although _names DataTable is updated. All the rows of _names have RowState == DataRowState.Unchanged Ok, I modified the handler: private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e) { DataRow row = _names.Rows[e.RowIndex]; row.BeginEdit(); row.EndEdit(); _da.Update(_names); } this variant really writes modified cell to database, but when I attempt to insert new row into grid, I get an error about an absence of row with index e.RowIndex So, I decided to improve the handler further: private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e) { if (_names.Rows.Count<e.RowIndex) { DataRow row = _names.Rows[e.RowIndex]; row.BeginEdit(); row.EndEdit(); } else { DataRow row = _names.NewRow(); row["NameText"] = dataGridView1["NameText", e.RowIndex].Value; _names.Rows.Add(row); } _da.Update(_names); } Now the really strange things happen when I insert new row to grid: the grid remains what it was until _names.Rows.Add(row); After this line THREE rows are inserted into table - two rows with the same value and one with Null value. The slightly modified code: DataRow row = _names.NewRow(); row["NameText"] = "--------------" _names.Rows.Add(row); inserts three rows with three different values: one as entered into the grid, the second with "--------------" value and third - with Null value. I really got stuck in guessing what is happening.

  • How to access individual items in Android GridView?

    - by source.rar
    Hi, I'm trying to create a game with a 9x9 grid with GridView. Each item in the grid is a TextView. I am able to set the initial values of each item in the grid within the getView() method to "0", however I want to change the value of each grid individually after this but have been unable to do so. I tried adding an update() function in my extended GridAdapter class that takes a position and a number to update at that position but this doesnt seem to be working. public void update(int position, int number) { TextView cell; cell = (TextView) getItem(position); if (cell != null) { cell.setText(Integer.toString(number)); } } Doe anyone know how this can be achieved? Here's the whole GridAdapter class in case require, public class SudokuGridAdapter extends BaseAdapter { private Context myContext; private TextView[] myCells; public SudokuGridAdapter(Context c) { myContext = c; myCells = new TextView[9*9]; } @Override public int getCount() { // TODO Auto-generated method stub return 9*9; } @Override public Object getItem(int position) { return myCells[position]; } @Override public long getItemId(int position) { // TODO Auto-generated method stub return 0; } @Override public View getView(int position, View convertView, ViewGroup parent) { TextView cell; if (myCells[position] == null) { cell = myCells[position] = new TextView(myContext); cell.setText("0"); } else { cell = myCells[position]; } return cell; } public void update(int position, int number) { TextView cell; cell = (TextView) getItem(position); if (cell != null) { cell.setText(Integer.toString(number)); } } }

  • what are good ways to implement search and search results using ajax?

    - by Amr ElGarhy
    i have some text box in a page and in the same page there will be a table 'grid' like for holding the search result. When the user start editing and of the textbox above, the search must start by sending all textboxs values to the server 'ajax', and get back with the results to fill the below grid. Notes: This grid should support paging, sorting by clicking on headers and it will contains some controls beside the results such as checkboxs for boolean values and links for opening details in another page. I know many ways to do this some of them are: 1- updatepanel around all of these controls and thats it "fast dirty solution" 2- send the search criteria using ajax request using JQuery post function for example and get back the JSON result, and using a template will draw the grid "clean but will take time to finish and will be harder to edit later". 3- .... My question is: What do you think will be the best choice to implement this scenario? because i face this scenario too much, and want to know which implementation will be better regarding performance, optimization, and time to finish. I just want to know your thoughts about this issue.

  • Vectors or Java arrays for Tetris?

    - by StackedCrooked
    I'm trying to create a Tetris-like game with Clojure and I'm having some trouble deciding the data structure for the playing field. I want to define the playing field as a mutable grid. The individual blocks are also grids, but don't need to be mutable. My first attempt was to define a grid as a vector of vectors. For example an S-block looks like this: :s-block { :grids [ [ [ 0 1 1 ] [ 1 1 0 ] ] [ [ 1 0 ] [ 1 1 ] [ 0 1 ] ] ] } But that turns out to be rather tricky for simple things like iterating and painting (see the code below). For making the grid mutable my initial idea was to make each row a reference. But then I couldn't really figure out how to change the value of a specific cell in a row. One option would have been to create each individual cell a ref instead of each row. But that feels like an unclean approach. I'm considering using Java arrays now. Clojure's aget and aset functions will probably turn out to be much simpler. However before digging myself in a deeper mess I want to ask ideas/insights. How would you recommend implementing a mutable 2d grid? Feel free to share alternative approaches as well. Source code current state: Tetris.clj (rev452)

  • Make div expand only horizontally when more floating divs are added to it

    - by Wesam
    I am trying to make a div that contains other floating divs to adjust its width such that adding more floating divs (dynamically using jQuery) will only expand the div in its width, not allowing the floating divs to create a new line. Therefore, I want to fix this issue such that each div with class grid-row only expands in width, and so I will be able to scroll using the overflow: scroll for the parent grid div. I have searched a lot for answers, and it seems that it is a famous issue. However, non of the answer solved my problem. I am currently doing this: <div id="grid_container"> <div id="grid"> <div class="grid_row"> <div class="module" id="experience"> Experience </div> <div class="header"> Google </div> <div class="header"> Microsoft </div> </div> <div class="grid_row"> </div> </div> </div> CSS: body { } #grid_container { margin: 50px auto; width: 500px; height: 500px; padding: 10px; border: black solid 1px; } #grid { overflow:scroll; height: 100%; } .grid_row { clear: both; height: 50px; } .module, .header{ padding: 10px; float: left; border: gray solid 1px; }
