What do you want to be dragged between these two buttons ? (May be you need to interchange the captions each other ?)

Or do you want just to drag them between themself? Waiting for input addition.

BTW Partha, i've found that you've a few questions still open, and in one of these i've provided a full working solution, but it seems that you've abandoned it.

What's going on? If you need more help in your questions just ask for it...

I want to drag and drop between ToolButtons to interchange their positions.

F68, the questions are open because I did'nt find an acceptable reply, however I am sorry that I missed the one you replied because I solved the problem myself. But you deserve the points, Thanks a lot.
