Hello, I have enabled grouping on my programatically (dynamic) created RadGrid. I am persisting the group expressions through cookies and all it working well. By default, all the groups are expanded. When I collapse a set of rows they collapse just fine. However, when I try to expand those same rows nothing happens. The page appears to be doing a post-back, but not change is made on the screen. No error, no message at all.
I'm guessing that the code is executing a toggle operation and believes (due to it's dynamic nature) that I clicked on an expanded node that needs to be collapsed. And thus it is doing exactly what it is supposed to. Is there a way to have the expand/collapse done on the client side so that a post-back does not have to occur? Or does the fact that the item collapsed needs to be persisted in some manner. Any direction in either path would be appreciated.

Hi Alex,
If you want the groups to expanded/collapsed client-side, you can set the GroupLoadMode to Client. But this can lead to change in the logic for persisting the expanded, collapsed items.
However, can you specify how is the grid bound, and if possible to share a stripped version of your code, so we try finding what went wrong there?
Best wishes,
