Key Press Events and GridControl

I have a GridControl and I only want to allow numerical data to be entered into each cell. I want to ignore any keypress that doesn't have the value '0' to '9', '.', '-' and Insert and Delete. I have found hooking onto the event: CurrentCellValidateString Will work in stopping a keypress when first trying to start editing the cell, but if the cell has already begun editing, you can enter any key after that. What event should I be hooking onto for this type of operation? cheers Alan

Try handling CurrentCellKeyPress, and set e.Handled = true for any e.KeyChar that you do not want the cell to get.

private void gridControl1_CurrentCellKeyPress(object sender, KeyPressEventArgs e)
{
	GridCurrentCell cc = this.gridControl1.CurrentCell;

	//restrict col 2 to numbers
	if(cc.ColIndex == 2 && !char.IsDigit(e.KeyChar) 
            && e.KeyChar != ’.’ && && e.KeyChar != ’-’)
		e.Handled = true; //ignore it
}
