Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

Public Event UserDeletingRow As DataGridViewRowCancelEventHandler

This event can be canceled to prevent a row deletion from being completed.

For more information about handling events, see NIB: Consuming Events.

The following code example demonstrates how to use the UserDeletingRow event to cancel the deletion of rows from the DataGridView if the starting balance row is included in the selection. This example is part of a larger example available in the SelectionChanged event.

Private Sub UserDeletingRow(ByVal sender As Object, _
    ByVal e As DataGridViewRowCancelEventArgs) _
    Handles DataGridView1.UserDeletingRow

    Dim startingBalanceRow As DataGridViewRow = DataGridView1.Rows(0)

    ' Check if the starting balance row is included in the selected rows
    If DataGridView1.SelectedRows.Contains(startingBalanceRow) Then
        ' Do not allow the user to delete the Starting Balance row.
        MessageBox.Show("Cannot delete Starting Balance row!")

        ' Cancel the deletion if the Starting Balance row is included.
        e.Cancel = True
    End If
End Sub
