Hi telerik support,
- In radgridview, when I apply grouping, some groups will automatically expand even if i scroll data (using EnableRowVirtualization = true).
I just want to expand the group when i click header group.
- Other hand, when grouping I select a record and update this record in code, the issues is UI not updated so i must use method ReBind().
(with same step, if i don't group data, everything is okay)
- Please tell me some infomation about grouping in radgridview.
Thanks a lot.
