  • Binding WPF DataGrid to DataTable using TemplateColumns

    - by Chris J
    I have tried everything and got nowhere so I'm hoping someone can give me the aha moment. I simply cannot get the binding to pull the data in the datagrid successfully. I have a DataTable that contains multiple columns with of MyDataType} public class MyData { string nameData {get;set;} boolean showData {get;set;} } MyDataType has 2 properties (A string, a boolean) I have created a test DataTable DataTable GetDummyData() { DataTable dt = new DataTable("Foo"); dt.Columns.Add(new DataColumn("AnotherColumn", typeof(MyData))); dt.Rows.Add(new MyData("Row1C1", true)); dt.Rows.Add(new MyData("Row2C1", false)); dt.AcceptChanges(); return dt; } I have a WPF DataGrid which I want to show my DataTable. But all I want to do is to change how each cell is rendered to show [TextBlock][Button] per cell with values bound to the MyData object and this is where I'm having a tonne of trouble. My XAML looks like this <Window.Resources><ResourceDictionary><DataTemplate x:Key="MyDataTemplate" DataType="MyData"> <StackPanel Orientation="Horizontal" > <Button Background="Green" HorizontalAlignment="Right" VerticalAlignment="Center" Margin="5,0,0,0" Content="{Binding Path=nameData}"></Button> <TextBlock Background="Green" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="5,0,0,0" Text="{Binding Path=nameData}"></TextBlock> </StackPanel> </DataTemplate></ResourceDictionary></Window.Resources> <Grid> <dg:DataGrid Grid.Row="1" AutoGenerateColumns="True" x:Name="dataGrid1" SelectionMode="Single" CanUserAddRows="False" CanUserSortColumns="true" CanUserDeleteRows="False" AlternatingRowBackground="AliceBlue" AutoGeneratingColumn="dataGrid1_AutoGeneratingColumn" ItemsSource="{Binding}" /> now all I do once loaded is to attempt to bind the DataTable to the WPF DataGrid dt = GetDummyData(); dataGrid1.ItemsSource = dt.DefaultView; The TextBlock and Button show up, but they don't bind, which leaves them blank. Could anyone let me know if they have any idea how to fix this. This should be simple, thats what Microsoft leads us to believe. I have set the Column.CellTemplate during the AutoGenerating event and still get no binding. Please help!!!

  • Capture each WPF MediaElement frame

    - by luvieere
    Is there a way to capture each WPF MediaElement frame? Like an event that fires at each rendered frame and allows me to access it. If MediaElement does not provide such functionality, how could it be implemented or what other control could I use? On a side note, is there such a control or method that would allow for off-screen fast rendering of media clips with frame capture? (so I could process frames as fast as possible)

  • WPF Debugging AvalonEdit binding to Document property.

    - by kubal5003
    Hello, all day long I am sitting and trying to find out why binding to AvalonEdits Document property isn't working. AvalonEdit is an advanced WPF text editor - part of the SharpDevelop project.(it's going to be used in SharpDevelop v4 Mirador). So when I set up a simple project - one TextEditor (that's the AvalonEdits real name in the library) and made a simple class that has one property - Document and it returns a dummy object with some static text the binding is working perfectly. However in real life solution I'm binding a collection of SomeEditor objects to TabControl. TabControl has DataTemplate for SomeEditor and there's the TextEditor object. <TabControl Grid.Column="1" x:Name="tabControlFiles" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" > <TabControl.Resources> <DataTemplate DataType="{x:Type m:SomeEditor}"> <a:TextEditor Document="{Binding Path=Document, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource NoopConverter}, IsAsync=True}" x:Name="avalonEdit"></a:TextEditor> </DataTemplate> </TabControl.Resources> <TabControl.ItemContainerStyle> <Style BasedOn="{StaticResource TabItemStyle}" TargetType="{x:Type TabItem}"> <Setter Property="IsSelected" Value="{Binding IsSelected}"></Setter> </Style> </TabControl.ItemContainerStyle> </TabControl> This doesn't work. What I've investigated so far: DataContext of TextEditor is set to the proper instance of SomeEditor TextEditors Document property is set to some other instance than SomeEditor.Document property when I set breakpoint to no-op converter that is attached to that binding it shows me the correct value for Document (the converter is used!) I also dug through the VisualTree to obtain reference to TextEditor and called GetBindingExpression(TextEditor.DocumentProperty) and this did return nothing WPF produces the following information: System.Windows.Data Information: 10 : Cannot retrieve value using the binding and no valid fallback value exists; using default instead. BindingExpression:Path=Document; DataItem='SomeEditor' (HashCode=26280264); target element is 'TextEditor' (Name='avalonEdit'); target property is 'Document' (type 'TextDocument') SomeEditor instance that is bound to already has a created and cached copy of Document before the binding occurs. The getter is never called. Anyone can tell me what might be wrong? Why BindingExpression isn't set ? Why property getter is never called?

  • How to convert a winforms project to wpf project

    - by mblaze
    I converted a Winforms project by hand-editing the proj file. Changed project type guids and added an application definition section, and now I can add WPF Windows, Pages, etc. to the project. One thing that doesn't work is, the files I added do not have autogenerated cs files, and every new window component are missing their InitializeComponent method. Any ideas?

  • Simplest way to create busy animation in WPF

    - by drasto
    I mentioned that there is no standard busy control in WPF. So what's the easiest way to display animated busy circle (not progress bar) such as your browser displays when loading a page ? Please if you suggest downloading control from internet make sure that this control is for free and with no licence restriction (such as I would be forced to GPL my application if I use it). Thank you in advance

  • WPF Radiobutton equivalent

    - by baron
    What is the WPF equivalent for WinForms radio button CheckedChanged? I have your basic 2 radio button set up, where when one is selected a textbox is enabled and when the other is selected it is disabled. For the time being I was using RadioButton_Checked, except, I set IsChecked true for one button in the xaml. When I reference the textbox in that Checked method it throws NullReferenceException... Let me know if you need code.

  • Prevent scrollbars with WPF WebBrowser displaying content

    - by Kevin Montrose
    I'm using the WPF WebBrowser component to display some very simple HTML content. However, since I don't know the content size in advance, I'm currently getting scrollbars on the control when I load certain datasets. Basically, how can I force (or otherwise effect the equivalent of forcing) the WebBrowser to expand in size so that all content is displayed without the need for scrollbars?

  • WPF drag distance threshold

    - by justin984
    I have a program with two WPF treeviews that allow dragging and dropping between the two. The problem is, it can be annoying to open / close items on the treeviews because moving the mouse just one pixel while holding the left mouse button triggers the drag / drop functionality. Is there some way to specify how far the mouse should move before it's considered a drag / drop? Thanks!

  • WPF: Binding to commands in code behind

    - by sofri
    Hi, I have an WPF Microsoft Surface Applikation and I'm using MVVM-Pattern. I have some buttons that are created in code behind. And I would like to bind commands to them but I only know how that works in the XAML like this: <Custom:SurfaceButton Command="{Binding SaveReservationCommandBinding, Mode=OneWay}"/> But I cannot do it like this because my buttons do not exist in the XAML, only in the code behind. So how would a command binding like that works in code behind?

  • Richtextbox wpf binding

    - by Alex Maker
    To do DataBinding of the Document in a WPF RichtextBox, I saw 2 Solutions so far, which are to derive from the RichtextBox and add a DependencyProperty, and also the solution with a "proxy". Neither the first or the second are satisfactory. Does somebody know another solution, or instead, a commercial RTF control which is capable of DataBinding? The normal Textbox ist not an alternative, since we need text formating. Any idea?

  • Preventing a WPF Expander from expanding when header is clicked

    - by emddudley
    How can I prevent a WPF Expander from expanding when its header is clicked? I would like my Expander to expand or collapse only when the expand button itself is clicked. I imagine the answer has something to do with canceling a bubbled event. If possible I would like to implement the solution in XAML while avoiding retemplating the entire Expander.
