Threading model problem - Drag Drop registration failed

[Gil Kalo]

Hi,

Assuming we have a GroupBar,GroupBarItem and a GroupView, when changing the app threading model from STA to MTA (using an attribute), the following code: "GroupBarItem.Client = GroupBarView" is failed with exception "Drag Drop registration failed":

Any ideas?

This does not appear to be a grid question, does it?

I think MTA does not support OLE D&D. So, you probably will have to make sure the AllowDrop property on all your forms and controls is set to false.
