Hi Pranjal,
Basically, clicking the column header applies new sorting option to the DataSource, which in turn forces the Grid to be redrawn. This behavior is expected and currently it is not possible to override it using built-in options. You could however, achieve similar behavior by using the Grid's edit, save and cancel events to cover the header with a transparent div as explained in
this forum thread.
