}
// By handling the CurrentCellErrorMesage event the ErrorMessage box can also be hidden.
this.gridControl1.CurrentCellErrorMessage += new GridCurrentCellErrorMessageEventHandler(gridControl1_CurrentCellErrorMessage);
this.gridControl1.CurrentCellErrorMessage += new GridCurrentCellErrorMessageEventHandler(gridControl1_CurrentCellErrorMessage);
