Assembly: System.Data (in System.Data.dll)
When you create a delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, until you remove the delegate. For more information about delegates, see Events and Delegates.
The following example adds a and the procedure to handle the event when a row is changed. The procedure prints the action and value of the changed row.
Private dataTable As DataTable Private Sub [AddHandler]() dataTable = New DataTable("dataTable") AddHandler dataTable.RowChanged, AddressOf dataTable_Changed End Sub Private Sub dataTable_Changed _ (sender As Object, e As System.Data.DataRowChangeEventArgs) Console.WriteLine("Row Changed", e.Action, _ e.Row(dataGrid1.CurrentCell.ColumnNumber)) End Sub
