Hello,

 You can use EventToCommand in Blend.

This is solution we are using, please note that u have to start using your namespace and assembly in xaml instead of defaults:
It could be easily rewrote into attachable property which is probably better solution.

public class YoursRadGridView : Telerik.Windows.Controls.RadGridView
   {
       public YoursRadGridView ()
       {
           doubleClickHandler = new MouseButtonEventHandler((sender, args) =>
           {
               if (args.ClickCount % 2 == 0)
                   if (DoubleClickRowCommand != null)
                       DoubleClickRowCommand.Execute(SelectedItem);                  
           });
 
           RowLoaded += (s, e) =>
           {
               e.Row.AddHandler(GridViewRow.MouseLeftButtonDownEvent, doubleClickHandler, true);
           };
           RowUnloaded += (s, e) =>
           {
               e.Row.RemoveHandler(GridViewRow.MouseLeftButtonDownEvent, doubleClickHandler);
           };
       }
 
       public ICommand DoubleClickRowCommand
       {
           get { return (ICommand)GetValue(DoubleClickRowCommandProperty); }
           set { SetValue(DoubleClickRowCommandProperty, value); }
       }
 
       // Using a DependencyProperty as the backing store for SelectedItemsEx.  This enables animation, styling, binding, etc...
       public static readonly DependencyProperty DoubleClickRowCommandProperty =
           DependencyProperty.Register("DoubleClickRowCommand", typeof(ICommand), typeof(MsRadGridView), new PropertyMetadata(null));
 
       MouseButtonEventHandler doubleClickHandler;
   }
