I am using both multi selection and show group drop area:
this.gdc.ListBoxSelectionMode = GridSelectionMode.None;
this.gdc.AllowSelection = GridSelectionFlags.Cell | GridSelectionFlags.Multiple | GridSelectionFlags.Keyboard | GridSelectionFlags.Shift;
this.gdc.AllowDragColumns = true;
this.gdc.ShowGroupDropArea = true;
Please see the attached example.
If I drag a column such as "Name" to the drop area.
And then expand one of the group areas defined.
I cannot multi select the cells in a column.
Is this possible.
Thanks.
Mary
