CellType = "DropDownGrid"

[Dominic Morris]

When I have a cell set to this type, and click on its dropdown button so that a sub-grid is displayed:

Updates to the original grid''s DataSource cause the sub-grid to dissappear.

Is there any way to prevent this?

Here is something to try. In TableControlCurrentCellShowingDropDown, you can lock the currentcell:

this.gridGroupingControl1.TableControl.CurrentCell.Lock();

Then you can handle TableControlMouseDown and unlocked it.

private void gridGroupingControl1_TableControlMouseDown(object sender, GridTableControlMouseEventArgs e)
{
	if(this.gridGroupingControl1.TableControl.CurrentCell.IsLocked)
		this.gridGroupingControl1.TableControl.CurrentCell.Unlock();
}
