Property Grid - Splitter Bar

[WILLIAM]

Good Morning Telerik Team,

I'm trying to find the Splitter Bar property for the Property Grid and, more so, the event that is fired with it is moved/resized.

Thanks!!

Hi,

You can try to use ChildrenOfType<>() extension method and find the underlying element. In your case it will be the PropertyGridColumnResizer. Please check the following code snippet for a reference:

private void propertyGrid_Loaded(object sender, RoutedEventArgs e)
      {
          var cr = this.propertyGrid.ChildrenOfType<PropertyGridColumnResizer>().FirstOrDefault().ChildrenOfType<Thumb>().FirstOrDefault();
          cr.DragDelta += new DragDeltaEventHandler(cr_DragDelta);
      }

I hope this helps.

Thanks for the quick reply, I will give that a try!

This almost works. When the PropertyGrid.Loaded event fires the first time, there is no PropertyGridColumnReszier in the tree.  Only on subsequent PropertyGrid.Loaded events is there PropertyGridColumnReszier.  I need to get the first time.  Is there a different event on the PropertyGrid that happens later where the PropertyGridColumnResizer has been added to the tree?

Also, once I do get the PropertyGridColumnResizer, there is no Thumb in the tree either.

Hello,

You can try to handle RadPropertyGrid's FieldLoaded event and execute the following code with dispatcher: 

private void propertyGrid_FieldLoaded(object sender, FieldEventArgs e)
       {
           this.Dispatcher.BeginInvoke(new Action(() =>
           {
               var cr = e.Field.ChildrenOfType<PropertyGridColumnResizer>().FirstOrDefault().ChildrenOfType<Thumb>().FirstOrDefault();
               cr.DragDelta += new DragDeltaEventHandler(cr_DragDelta);
           }));

       }

       void cr_DragDelta(object sender, DragDeltaEventArgs e)
       {
       }
   }

Where is this event?  I don't see the PropertyGrid.FieldLoaded event.

Hi,

This event was added with Q1 2013 version of our controls.
