You can handle the CurrentCellShowingDropDown event, and swap the drop list out at that point. Here is a rough try at it. private void gridDataBoundGrid1_CurrentCellShowingDropDown(object sender, GridCurrentCellShowingDropDownEventArgs e) { GridCurrentCell cc = this.gridDataBoundGrid1.CurrentCell; if(cc.ColIndex > 0 && cc.RowIndex == 1) //filterrow { GridComboBoxCellRenderer cr = cc.Renderer as GridComboBoxCellRenderer; if(cr != null) { StringCollection sc = new StringCollection(); sc.Add("(none)"); for(int i = this.gridDataBoundGrid1.TopRowIndex; i <= this.gridDataBoundGrid1.ViewLayout.LastVisibleRow; ++i) { string s = this.gridDataBoundGrid1[i, cc.ColIndex].FormattedText; if(sc.IndexOf(s) == -1) sc.Add(s); } cr.ListBoxPart.DataSource = sc; } } }
