  • WPF binding to a boolean on a control

    - by Jose
    I'm wondering if someone has a simple succinct solution to binding to a dependency property that needs to be the converse of the property. Here's an example I have a textbox that is disabled based on a property in the datacontext e.g.: <TextBox IsEnabled={Binding CanEdit} Text={Binding MyText}/> The requirement changes and I want to make it ReadOnly instead of disabled, so without changing my ViewModel I could do this: In the UserControl resources: <UserControl.Resources> <m:NotConverter x:Key="NotConverter"/> </UserControl.Resources> And then change the TextBox to: <TextBox IsReadOnly={Binding CanEdit,Converter={StaticResource NotConverter}} Text={Binding MyText}/> Which I personally think is EXTREMELY verbose I would love to be able to just do this(notice the !): <TextBox IsReadOnly={Binding !CanEdit} Text={Binding MyText}/> But alas, that is not an option that I know of. I can think of two options. Create an attached property IsNotReadOnly to FrameworkElement(?) and bind to that property If I change my ViewModel then I could add a property CanEdit and another CannotEdit which I would be kind of embarrassed of because I believe it adds an irrelevant property to a class, which I don't think is a good practice. The main reason for the question is that in my project the above isn't just for one control, so trying to keep my project as DRY as possible and readable I am throwing this out to anyone feeling my pain and has come up with a solution :)

  • WPF: Change padding depending of container ?

    - by Alex Ilyin
    I have UserControl named MyUserControl, and another UserControl named MyContainer. I want MyUserControl to have padding 10 if it is placed inside MyContainer and 15 otherwise. Shortly, I want <MyContainer> <MyUserControl> Hello </MyUserControl> </MyContainer> to look like <MyContainer> <UserControl Padding="10"> Hello </UserControl> <MyContainer> and <MyUserControl> Hello </MyUserControl> to look like <UserControl Padding="15"> Hello </UserControl>

  • Dynamically update Font Size of application with a single trigger in WPF

    - by Sukan
    I have an application which has different font sizes for different controls say Button: 10, TextBlock : 12 etc. I want to give options to the user where he can select any one of the below say Normal , Small, Big, Bigger. Suppose one selects "small" I would want to decrease every distinct font size by 2. If "Big", I would want to increase every font size by 2. I hope we can do this using converter sending actual font size as parameter and render as per the selected choice if I am not wrong. What will be the best option. Sorry if my doubt is absurd or silly. Thank you.

  • WPF: Reset the positions of scatterviewitems?

    - by sofri
    Hi, I have a scatterview with some items in it which I place with Orientation und Center. Now I want to have the possibility to reset the positions of the scatterviewitems after scaling, rotating and moving them, while the program is running. At the moment I do it this way: private void Reset_ContactTapGesture(object sender, Microsoft.Surface.Presentation.ContactEventArgs e) { item1.Center = new Point(150,150); item1.Orientation = 15; item1.Width = 100; item1.Height = 150; } Is there a better way to do it?

  • wpf custom control problem

    - by josika
    Hi! I have a problem, and I have not found the solution yet. I woud like to create a base custom control and use it in another custom control. The base control work fine when I use in a window, but when I use in the other custom control, the binding does not work. What's wrong with my code? Code: Model: public class ElementModel { public string Name { get; set; } public string FullName { get; set; } } The base control: public class ListControl : Control { static ListControl() { DefaultStyleKeyProperty.OverrideMetadata(typeof(ListControl), new FrameworkPropertyMetadata(typeof(ListControl))); } public ListControl() { SetValue(ElementListProperty, new List<ElementModel>()); } public static readonly DependencyProperty ElementListProperty = DependencyProperty.Register( "ElementList", typeof(List<ElementModel>), typeof(ListControl), new FrameworkPropertyMetadata(new List<ElementModel>()) ); public List<ElementModel> ElementList { get { return (List<ElementModel>)GetValue(ElementListProperty); } set { SetValue(ElementListProperty, value); } } } The Wrapper Control: public class ListWrapper : Control { static ListWrapper() { DefaultStyleKeyProperty.OverrideMetadata(typeof(ListWrapper), new FrameworkPropertyMetadata(typeof(ListWrapper))); } public ListWrapper() { SetValue(EMListProperty, new List<ElementModel>()); } public static readonly DependencyProperty EMListProperty = DependencyProperty.Register( "EMList", typeof(List<ElementModel>), typeof(ListWrapper), new FrameworkPropertyMetadata(new List<ElementModel>()) ); public List<ElementModel> EMList { get { return (List<ElementModel>)GetValue(EMListProperty); } set { SetValue(EMListProperty, value); } } } Generic.xaml <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:UIControl"> <Style TargetType="{x:Type local:ListControl}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type local:ListControl}"> <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}"> <ListBox ItemsSource="{TemplateBinding ElementList}"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <Label Content="Name:"/> <TextBlock Text="{Binding Path=Name}" /> <Label Content="Full name:"/> <TextBlock Text="{Binding Path=FullName}" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> <Style TargetType="{x:Type local:ListWrapper}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type local:ListWrapper}"> <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}"> <local:ListControl ElementList="{TemplateBinding EMList}" /> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> If I put the controls in the window and binding properties, than the ListControl works fine and shows the elements, but the WrapperList does not. <Window x:Class="MainApplication.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:ui="clr-namespace:UIControl;assembly=UIControl" Title="Window1" Height="304" Width="628"> <Grid> <ui:ListControl x:Name="listCtr" ElementList="{Binding Path=EList}" HorizontalAlignment="Left" Width="300" /> <ui:ListWrapper x:Name="listWrp" EMList="{Binding Path=EList}" HorizontalAlignment="Right" Width="300" Background="Gray"/> </Grid> Project archive

  • WPF: Template Binding in Control template

    - by Sam
    I have the following control template. I wish to set the source property for the image control in the control template using Template Binding. But since this is a control template for button control and the button control doesn't have source property, i can't use TemplateBinding in this case. <ControlTemplate x:Key="BtnTemplate" TargetType="Button"> <Border CornerRadius="5" Margin="15" Cursor="Hand"> <StackPanel> <Image Name="Img" Style="{StaticResource ImageStyle}" Source="temp.jpg" Height="100" Width="100" Margin="5"></Image> <Label Content="{TemplateBinding Content}" Background="Transparent" Margin="2"></Label> </StackPanel> </Border> </ControlTemplate> Since i have to set different images for different instances of button, i can't hardcode the path as well. Please let me know how to tackle this situation.

    I have two xaml file one is MainWindow.xaml and other is userControl EditTaskView.xaml. In MainWindow.xaml it consists of listbox and when double clicked any item of listbox, it displays edit window (EditView userControl). Whenever edit window gets displayed, it plays an animation (sliding from right to left). The EditView userControl has two buttons 'Save' and 'Cancel'. Now I want to add animation (sliding edit window from left to right) when any of the button (Save or Cancel) button is clicked. When 'Save' or 'Cancel' button is clicked, it Collapse the edit window. Here is the story board which slides window from right to left. <Storyboard x:Key="AnimateEditView"> <ThicknessAnimationUsingKeyFrames Storyboard.TargetProperty="(FrameworkElement.Margin)" Storyboard.TargetName="EditTask" > <EasingThicknessKeyFrame KeyTime="0" Value="100,0,0,0"> <EasingThicknessKeyFrame.EasingFunction> <ExponentialEase EasingMode="EaseOut"/> </EasingThicknessKeyFrame.EasingFunction> </EasingThicknessKeyFrame> <EasingThicknessKeyFrame KeyTime="0:0:1" Value="0,0,0,0"> <EasingThicknessKeyFrame.EasingFunction> <ExponentialEase EasingMode="EaseOut"/> </EasingThicknessKeyFrame.EasingFunction> </EasingThicknessKeyFrame> </ThicknessAnimationUsingKeyFrames> </Storyboard> </Window.Resources> <Window.Triggers> <EventTrigger RoutedEvent="Control.MouseDoubleClick" SourceName="lstBxTask"> <BeginStoryboard Storyboard="{StaticResource AnimateEditView}"/> </EventTrigger> <Window.Triggers> Here is the xaml within MainWindow. <ListBox x:Name="lstBxTask" Style="{StaticResource ListBoxItems}" MouseDoubleClick="lstBxTask_MouseDoubleClick"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <Rectangle Style="{StaticResource LineBetweenListBox}"/> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Taskname}" Style="{StaticResource TextInListBox}"/> <Button Name="btnDelete" Style="{StaticResource DeleteButton}" Click="btnDelete_Click"/> </StackPanel> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> <ToDoTask:EditTaskView x:Name="EditTask" Grid.Row="0" Grid.RowSpan="3" Grid.ColumnSpan="2" Visibility="Collapsed" > Any suggestions?

  • WPF ObservableCollection in xaml

    - by Cloverness
    Hi, I have created an ObservableCollection in the code behind of a user control. It is created when the window loads: private void UserControl_Loaded(object sender, RoutedEventArgs e) { Entities db = new Entities(); ObservableCollection<Image> _imageCollection = new ObservableCollection<Image>(); IEnumerable<library> libraryQuery = from c in db.ElectricalLibraries select c; foreach (ElectricalLibrary c in libraryQuery) { Image finalImage = new Image(); finalImage.Width = 80; BitmapImage logo = new BitmapImage(); logo.BeginInit(); logo.UriSource = new Uri(c.url); logo.EndInit(); finalImage.Source = logo; _imageCollection.Add(finalImage); } } I need to get the ObservableCollection of images which are created based on the url saved in a database. But I need a ListView or other ItemsControl to bind to it in XAML file like this: But I can't figure it out how to pass the ObservableCollection to the ItemsSource of that control. I tried to create a class and then create an instance of a class in xaml file but it did not work. Should I create a static resource somehow Any help will be greatly appreciated.

  • Why won't my WPF XAML Grid TranslateTransform.X ?

    - by George
    I'm able to change the width/height of the grid using this, so why won't it work when I use (Grid.RenderTransform).TranslateTransform.X as such: <Window.Triggers> <EventTrigger RoutedEvent="Button.Click" SourceName="button"> <BeginStoryboard> <Storyboard> <DoubleAnimation Storyboard.TargetProperty="(Grid.RenderTransform).(TranslateTransform.X)" From="0" To="200" Storyboard.TargetName="grid" Duration="0:0:2" /> </Storyboard> </BeginStoryboard> </EventTrigger> </Window.Triggers> The application loads etc, but nothing happens when the button is clicked. Here is the XAML for my grid: <Grid x:Name="grid" Height="714" Canvas.Left="240" Canvas.Top="8" Width="360" RenderTransformOrigin="0.5,0.5"> <Grid.Background> <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0"> <GradientStop Color="Black" Offset="0"/> <GradientStop Color="White" Offset="1"/> </LinearGradientBrush> </Grid.Background> <Grid.ColumnDefinitions> <ColumnDefinition Width="0*"/> <ColumnDefinition/> </Grid.ColumnDefinitions> </Grid> Note that I've tried many different Canvas.Left values, to no avail.

  • Why cant i add Orientation property to the style setter in WPF

    - by nihi_l_ist
    When i write something like this: <Style x:Key="panelS"> <Setter Property="Orientation" Value="Horizontal" /> <Setter Property="DockPanel.Dock" Value="Top" /> </Style> I get the error that says: Cannot resolve the Style Property 'Orientation'. Verify that the owning type is the Style's TargetType, or use Class.Property syntax to specify the Property. Sure i have a Dock panel with many Stackpanels in it so i want to move Stackpanel's properties to the style. But there is this error and i dont quite understand what it means and what is the workaround(..i'd wanted not to assign Orientation on every Stackpanel).

  • WPF tree data binding model & repository

    - by Am
    Hi, I have a well defined tree repository. Where I can rename items, move them up, down, etc. Add new and delete. The data is stored in a table as follows: Index Parent Label Left Right 1 0 root 1 14 2 1 food 2 7 3 2 cake 3 4 4 2 pie 5 6 5 1 flowers 8 13 6 5 roses 9 10 7 5 violets 11 12 Representing the following tree: (1) root (14) (2) food (7) (8) flowers (13) (3) cake (4) (5) pie (6) (9) roeses (10) (11) violets (12) or root food cake pie flowers roses violets Now, my problem is how to represent this in a bindable way, so that a TreeView can handle all the possible data changes? Renaming is easy, all I need is to make the label an updatble field. But what if a user moves flowers above food? I can make the relevant data changes, but they cause a complete data change to all other items in the tree. And all the examples I found of bindable hierarchies are good for non static trees.. So my current (and bad) solution is to reload the displayed tree after relocation change. Any direction will be good. Thanks

  • WPF EDitable ComboBox

    - by Amittai Shapira
    Hi! I want to create editable combo box with the following properties: 1. Bind the text property to my data model. 2. The data model may override the changes in the GUI, even in Selection changed. E.g. I can choose from 1, 2, 3 I choose 2, but some component down under changes it to 3. 3. Update the data model on the following events: 1. Selection Changed 2. Lose focus 3. Enter pressed (should behave the same as lost focus). I've been able to create such control, but it's pretty ugly (using many hacks) and I hoped there's a simpler way… Thanks in advance

  • In WPF Not Able to Kill Adobe Acrobat Reader

    - by Blam
    Problem with killing Adobe Acrobat Reader Code used to launch the process nativeProcess = new Process(); nativeProcess.StartInfo.FileName = filePath; nativeProcess.Start(); These are Microsoft Office Files or Adobe Acrobat. Code used to kill if (nativeProcess != null) { try { nativeProcess.Kill(); } catch { } } if (nativeProcess != null) { try { nativeProcess = null; } catch { } } My problem is that Adobe Acrobat Reader does not Kill() when the app is running as a Citrix app. If I log on at the Citrix box and run it as a Desktop app then Acrobat Kill() works. Microsoft Office Kills() fine as both a Citrix app and a Deskop app. User can close Acrobat Reader using the X or close
