How to show normal MessageBox instead of showing default ErrorMessageBox for DataValidation?

//Event Subscription. 
this.gridGroupingControl1.TableControlCurrentCellErrorMessage += newGridTableControlCurrentCellErrorMessageEventHandler(gridGroupingControl1_TableControlCurrentCellErrorMessage); 
 
void gridGroupingControl1_TableControlCurrentCellErrorMessage(object sender, GridTableControlCurrentCellErrorMessageEventArgs e) 
{ 
    //to cancel showing the default ErrorMessageBox support. 
    e.Inner.Cancel = true; 
 
    //To get the orginal error from e.Inner.Text 
    DialogResult result = MessageBox.Show(e.Inner.Text, "ErrorProvider", MessageBoxButtons.OKCancel); 
    if (result == DialogResult.Cancel) 
    { 
        e.TableControl.CurrentCell.CancelEdit(); 
    } 
} 

'Event Subscription. 
Private Me.gridGroupingControl1.TableControlCurrentCellErrorMessage += New GridTableControlCurrentCellErrorMessageEventHandler(AddressOf gridGroupingControl1_TableControlCurrentCellErrorMessage)
 
Private Sub gridGroupingControl1_TableControlCurrentCellErrorMessage(ByVal sender As Object, ByVal e As GridTableControlCurrentCellErrorMessageEventArgs)
    'to cancel showing the default ErrorMessageBox support. 
    e.Inner.Cancel = True
 
    'To get the orginal error from e.Inner.Text 
    Dim result As DialogResult = MessageBox.Show(e.Inner.Text, "ErrorProvider", MessageBoxButtons.OKCancel)
    If result = DialogResult.Cancel Then
        e.TableControl.CurrentCell.CancelEdit()
    End If
End Sub
