  How can I position the point of the ArrowCue with the point of the mouse cursor?  I've tried modifying the DragCueOffset but didn't see any difference. 
  See the telerik_arrow attachment to see what I'm currently getting. 
  See the telerik_arrow_want attachment to see what I would like to have. 
  
  We're using version 2011.1.315.1040 of the telerik controls.
  
  Thanks,
  Jeff

  I was able to adjust the arrow position by changing e.Options.ArrowCue.Padding.
  
  
  Thanks,

  My padding suggestion didn't work.  It only worked when I dragged from left to right.  Any other direction the arrow wasn't in the correct position due to padding on the wrong side.
  
  I came across a Telerik sample project found in this post which is what I want:
  http://www.telerik.com/community/forums/silverlight/drag-and-drop/drag-drop-create-line-connection.aspx
  
  Notice the point of the arrow and the point of the mouse cursor are the same.  That's the effect I'm looking for.  The sample project uses Telerik control version 2010.1.422.1040.  I am using 2011.1.315.1040.  Is this a bug in 2011.1.315.1040 or what am I doing wrong?
  
  Thanks,
  Jeff

  Hi Jeff,

   Indeed, this is an issue in version 2011.1.315.1040. In this situation I can suggest one of the following solutions:
  
   - upgrade to more recent version;
   - use custom style for arrow as shown in the attached project.

  The suggestion in the example code worked with Q1.2011.  Recently I upgraded to Q3.2011 and added RadDragAndDropManager.ExecutionMode = DragExecutionMode.Legacy to App.xaml.vb.
  
  The arrow displays but it is offset again, similar to my original question/post.  Any suggestions to make the point of the arrowcue to line-up with the point of the mouse arrow?
  
  
  Thanks,
  Jeff

  Hi,

   I have created sample project that illustrates how to implement custom arrow cue. That way you don't need to use legacy mode to display the arrow. In addition, you will have full control of the position and appearance of the arrow.
  
  Please have a look at the attachement and let us know if this helps.

  Kind regards,

  Thanks for the sample application.  I'm using a button as the source of the drag.  It looks like the exmaple you supplied is for a listbox.  I've attempted to modify this but I couldn't find a behavior for a button similar to ListBoxDragDropBehavior.  After searching the forum, it looks like you are trying to make the drag and drop feature easier to use for listboxes, gridview, and treeview (http://www.telerik.com/community/forums/silverlight/drag-and-drop/example-listbox-treeview-gridview-scheduleview-drag-drop-reorder-items-and-more.aspx)
  
  Do you have an exmaple for a button?
