Hi together, I have gridgroupingcontrol with a cell value of celltype "ComboBox". Furthermore the GridDropDownStyle attribute is set to "Exclusive". How can I prevent that a user can delete the content of this cell (then I get a blank cell with an down arrow on the right). I want that always one member of the dropdownlist is visible in the cell. Cheers, Markus

Hi Markus You can catch the pressing of Delete key in the TableControlCurrentCellKeyDown event and make its "Handled" property true if it is a combobox column. private void gridGroupingControl1_TableControlCurrentCellKeyDown(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlKeyEventArgs e) { if(this.gridGroupingControl1.TableControl.CurrentCell.ColIndex == 3) { if (e.Inner.KeyCode == Keys.Delete || e.Inner.KeyCode == Keys.Back ) e.Inner.Handled = true; } } Attached is a sample.
