I am trying to resize the Docking Panels in Visual Studio 2010 at Design Time. I am able to resize/change the size of Docking Panels, & do the drag & drop operation at run-time but not able to do in the design view.
I would like to set the sizes at design time.

Could you help me with the solution?

There are some differences between the behavior of vs2008(2005) and vs2010 designers.
We are aware of this problem, but we cannot determine what cause it.

As a work around I can advice you to setup the panels by code.

We apologize for the inconvenience.

Best Regards,
