I adapted the prev sample to the control and now I have few problems, I'm a attaching link to the solution.
I implemented the drag and drop on the right grid.
Once you drag and place the mouse on the line between items it starts blinking in a loop.
Once you set :
RadDragAndDropManager.EnableNativeDrag = true;
The tooltip location is wrong.
Once you change the tabs few times - the drag and drop stops firing events and working in general.
Please reviews this problems.
