I am implementing a drag and drop between two grids, which works fine and drags and drops great.
however, when I do the first drag and drop I get this error:
Message=Object reference not set to an instance of an object.
at Telerik.Windows.Controls.DragDrop.RadDragAndDropManager.StartDragging() in c:\Builds\WPF_Scrum\Release_WPF_2010_Q2_SP1\Sources\Development\Core\Controls\DragDrop\RadDragAndDropManager.cs:line 1083
The error occurs once and when I continue running the code the next drag and drops works great.
I am doing the drag and drops from a dialog window invoked from within the software.
I am using Q2 SP1 release.
