automatically collapsing groups?

[Robbie]

I have a gridview that is grouped by one field.  When a cell in a row is changed and the focus is moved to another row, the group where the updated row resides in automatically collapses and the user has to expand the group again. I haven’t got a clue why it collapses and how to stop it from collapsing.

Can u please help me?

Many tanx in advance!

This issue has been addressed in our latest release Q2 2008. I would suggest you give it a try. We will highly appreciate any feedback you have.

Hi jack,
Thanks for the response. Unfortunately it is still happening in the Q2 2008 release :(
It even sometimes raises an exception (see below) when the user expands the group after it collapses.
I think it is related to the datasource of the radgridview:  a llblgen entity collection. See my other issue I have currently: http://www.telerik.com/community/forums/thread/b311D-bkcdek.aspx

(I’m currently using the 2008 Q2 trial version)
