How to set column width and row width of the grid shown in MultiColumnComboBox's drop down?

Platform: WinForms |
Control: MultiColumnComboBox |

Setting column width and row width of the grid shown in MultiColumnComboBox's drop down can be achieved by handling the DropDown event of the MultiColumnComboBox. In the event handler code, use ColWidths and RowHeights properties of the embedded grid in the MultiColumnComboBox.ListBox.


private void MultiColumnComboBox1_DropDown(object sender, EventArgs e)


GridControl grid = this.MultiColumnComboBox1.ListBox.Grid;

for (int i = 1; i <= dt.Rows.Count; i++)


grid.ColWidths[i] = 100;

grid.RowHeights[i] = 35;




Private Sub MultiColumnComboBox1_DropDown(ByVal sender As Object, ByVal e As EventArgs) Handles MultiColumnComboBox1.DropDown

Dim grid As GridControl = Me.MultiColumnComboBox1.ListBox.Grid

For i As Integer = 1 To dt.Rows.Count

grid.ColWidths(i) = 100

grid.RowHeights(i) = 35

Next i

End Sub
