I found general Grid Grouping Control (GGC) problem which causes my app to expect serious troubles
It happens if we use GGC with DataSet set as a datasource and several tables in that DataSet. When just opened form collapse all tables.
Then expand them sequentially from the bottom to the top (expanding order is important). Last expanded in that way table expects some troubles:
=> try to edit any field - grid works not stable (when user is trying to edit one cell - another cell is
edited, or just entered value disappears).
and I can't edit cell by single mouse click.
I added a simple application to show this problem. Not all problems appear here, but cell editting doesn't start on the bugged table cell click - this is how You can see the problem here.
Hope to get a solution, thank you
