RadGrid Group Expand/Collapse not working properly on server mode

[Vijaianand]

I am using the radgrid with group expressions to group and binding in the code. The expand works but collapse doesn't work on the same group. When I expand the other group, it collapses the previously opened group but when it collapse the expanded group, it doesn't work. I tried GroupLoad = "Client". It works but after few expand and close, the grid doesn't refresh and shows all grid lines all over. 

What am I doing wrong?

Hello Vijai,

Check the following code library which explains the same.

Hi

I don't want to track all grouping expand/collapse. Please read my post carefully. I am just looking for the actual control funtionality to work. It needs to expand and collapse on the grouping when you groupbyexpression. It is not working when its "server" mode or default mode. When I put "client", it works but all the grid is messing up.
