How can i achieve this Please Guide me. Regards Ved

One way you can do this is to create your own mousecontroller. In version 3.3, a new controller was added to support moving columns just by mousing down on the header and dragging (not having to select the columns before mousing down). Here is a sample that modifies that mouse controller to support dragging columns with covered header cells. http://www.syncfusion.com/Support/user/uploads/CS_c7820925.zip
