What am I doing wrong with my ItemsControl & databinding?
- by Joel
I'm reworking my simple hex editor to practice using what I've recently learned about data binding in WPF. I'm not sure what I'm doing wrong here.
As I understand it, for each byte in the collection "backend" (inherits from ObservableCollection), my ItemsControl should apply the DataTemplate under resources. This template is just a textbox with a binding to a value converter. So I'm expecting to see a row of textboxes, each containing a string representation of one byte. When I use this XAML, all I get is a single line of uneditable text, which as far as I can tell doesn't use a textbox. What am I doing wrong?
I've pasted my XAML in below, with the irrelevant parts (Menu declaration, schema, etc) removed.
<Window ...>
<Window.Resources>
<local:Backend x:Key="backend" />
<local:ByteConverter x:Key="byteConverter" />
<DataTemplate DataType="byte">
<TextBox Text="{Binding Converter={StaticResource byteConverter}}" />
</DataTemplate>
</Window.Resources>
<StackPanel>
<ItemsControl ItemsSource="{Binding Source={StaticResource backend}}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
</StackPanel>
</Window>
