Hello Syncfusion Support,
I just discovered your product and trying to check whether it supports my needs or not. I was playing around a little bit with WinForms GridGroupingControl and found an issue I would need your help/advice.
If I have some groups expanded, but I update a row with a new value in a cell of a column that is already grouped (changing the source's DataRow object from code, not in UI), it seems that the whole grid collapses. I could understand if the groups that are affected are collapsed (as the item would move from one group to another, maybe even a new group has to be created), but the strange thing is that every group is collapsed on every level.
I created a workaround to persist the expanded states before the row update and reexpand the appropriate groups after it, but it causes some flickering, and of course it is more disturbing if I have more data or frequent updates. Could you please have a look at this issue and tell me if there is any better solution to that?
Thanks,
Thomas
