Code-behind for DataTemplate defined in a ResourceDictionary

Question

I've defined a DataTemplate in a ResourceDictionary. The template need some data (for populating a ListBox). Previously the template was a UserControl and the data was provided by setting the DataContext property.

Is there some way of using code-behind for a DataTemplate or is using an ObjectDataProvider to provide the data the only option?

Answer 1

You don't provide data to the DataTemplate, it's the other way around : you provide a DataTemplate to display some data. For instance, use a ContentControl, and set its Content to the data you want to display :

<ContentControl Content="{Binding SomeData}" />

The ContentControl will pick the adequate DataTemplate based on the type of the data. You can also specify the DataTemplate explicitly by using the ContentTemplate property of the ContentControl
