Hi Guillaume,
doing around with the context menu I encountered another issue,
I wasn't able to solve my self:
1: bring a cell in edit mode do not change it.
2.1: stay in the not edited cell an click row label or some emtpy space
on the right border and close
2.2: choose another cell in the same row do not change anything and close.
=> you will be asked if you want to save even though you didn't change
the data.
I could track this so far that frmEditGrid::OnCellChange is doing that
right if the row also changes.
I hope this helps you to spot the issue.
Regards Steffen
