Hi Pawan,

You can access the GridDropDownGridListControlCellRenderer and set the ListPart.ShowColumnHeader property to turn OFF/ON the dropdown list column header in a grid cell. Here is a code snippet to show this.

GridDropDownGridListControlCellRenderer cr = this.grid.TableControl.CellRenderers["GridListControl"] as GridDropDownGridListControlCellRenderer;
cr.ListControlPart.ShowColumnHeader = false;

Hi Pawan,

You can handle the TableControlCurrentCellShowingDropDown event and set the ListControlPart.ShowColumnHeader property for required cells in a grid. Here is a code snippet.

private void gridGroupingControl1_TableControlCurrentCellShowingDropDown(object sender, GridTableControlCurrentCellShowingDropDownEventArgs e)
{
GridCurrentCell cc = e.TableControl.CurrentCell;
if( cc.ColIndex == 1 && cc.RowIndex == 5)
{
GridDropDownGridListControlCellRenderer cr = cc.Renderer as GridDropDownGridListControlCellRenderer;
if( cr != null)
cr.ListControlPart.ShowColumnHeader = false;
}
}
