Expand drop down list on cell edit

I''m using a GridDataBoundGrid and some of my GridBoundColumns are of type ComboBox with a DropDownStyle of AutoComplete. My question is how can I expand the drop down list as the user begins to edit the cell? I could change to a DropDownStyle of Editable if it makes a difference. Thank you, Todd

Try handling the CurrentCellStartEditing and drop the list there. You have to make sure you do not get in a recursive loop though, as showing the DropDown will trigger a CurrentCellStartEditing event.

private bool showingDropDown = false;
private void gridControl1_CurrentCellStartEditing(object sender, CancelEventArgs e)
{
	GridCurrentCell cc = this.gridControl1.CurrentCell;
	if(this.gridControl1[cc.RowIndex, cc.ColIndex].CellType == "ComboBox"
		&& !cc.IsDroppedDown && !showingDropDown)
	{
		showingDropDown = true;
		cc.ShowDropDown();
		showingDropDown = false;
	}
}

Perfect, thanks. >Try handling the CurrentCellStartEditing and drop the list there. You have to make sure you do not get in a recursive loop though, as showing the DropDown will trigger a CurrentCellStartEditing event. > >
