Problem with Drag and Drop in Custom Activity Designer

Question

I have a few Custom Activity Designers. These designers are doing odd things with Drop actions on Textboxes in the Designer.  The Textboxes inside the Activity Designers duplicate the text droped onto them. I am Rehosting the Workflow Designer.

Example:

I drag from a Textbox the string “abc”.

Drop it into a Textbox inside the a Custom Activity Designer.

The text is duplicated and displays as “abcabc” inside the Textbox.

I’m not doing anything with any of the drag/drop events, Tunneling or otherwise so am at a total loss.

Anyone have any ideas?

This turned out to be an issue on setting up the control that acts as the Drag Source. Essentially: the text was added to DragDrop twice.
