1. I have a column in my Grid. It is not allowed to use grouping for this column (IsGroupable="False" ). When I try to drag-drop the column-title to the GroupPanel it just does not do anything. And that is what is expected, but the"not-allowed-image" did not show up.
2. Another column in the Grid is allowed to use grouping. When I drag-drop the title to the GroupPanel everything works fine.
But... when I try to drag-drop the title back again, this also works, but now the "not-allowed-sign" shows up.
Should this not be the other way around: the "not-allowed-sign" shows when I try to group a column with IsGroupable="False"...?
