Skip the deleting cell in gridWhen you set the ComboBox in a Grid and assign the dropdown style as exclusive, the cell text is removed from the ComboBox cell while pressing delete key or backspace key. Solution To overcome this problem, you can use the CurrentCellKeyDown event to handle the Delete & BackSpace keys. C# // On Form load
this.gridControl1.CurrentCellKeyDown += new KeyEventHandler(gridControl1_CurrentCellKeyDown);
void gridControl1_CurrentCellKeyDown(object sender, KeyEventArgs e)
{
GridCurrentCell cc = this.gridControl1.CurrentCell;
if (cc.Renderer.StyleInfo.CellType == "ComboBox" && cc.Renderer.StyleInfo.DropDownStyle == GridDropDownStyle.Exclusive)
{
// Pressing delete key or backspacekey
if (e.KeyCode == Keys.Back || e.KeyCode == Keys.Delete)
{
// not remove the cell content
e.Handled = true;
}
}
}
