Description

How to data bind a property from the model of the collection shown in the collection editor to the left side names of the editor opened when a collection property is selected.

Solution

1. Define a DataTemplate containing a TextBlock bound to a property from the model of the items in the collection.

   XAML

   	<Window.Resources>
   		<DataTemplate x:Key="CollectionEditorTemplate">
   			<TextBlock Text="{Binding Name}" />
   		</DataTemplate>
   	</Window.Resources>

2. Subscribe to the FieldLoaded event of RadPropertyGrid and set the ItemTemplate of the loaded editor. Do this only if the editor is an element of type CollectionEditorPicker.

   C#

   	private void radPropertyGrid_FieldLoaded(object sender, FieldEventArgs e)
   	{
   		var collectionEditorPicker = e.Field.Content as CollectionEditorPicker;
   		if (collectionEditorPicker != null)
   		{
   			Dispatcher.BeginInvoke(new Action(() => {
   				var editor = collectionEditorPicker.CollectionEditor;
   				editor.ItemTemplate = (DataTemplate)this.Resources["CollectionEditorTemplate"];
   			}));
   		}           
   	}
