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.

       <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.

       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"]; 
               })); 
           }            
       }
