Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the BindingManagerBase.DataError event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of a type that inherits from BindingManagerBase, such as a PropertyManager or CurrencyManager. Then name the instance BindingManagerBase1 and ensure that the event handler is associated with the BindingManagerBase.DataError event.

private void BindingManagerBase1_DataError(Object sender, BindingManagerDataErrorEventArgs e) {
    System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
    messageBoxCS.AppendFormat("{0} = {1}", "Exception", e.Exception);
    messageBoxCS.AppendLine();
    MessageBox.Show(messageBoxCS.ToString(), "DataError Event");
}
Private Sub BindingManagerBase1_DataError(sender as Object, e as BindingManagerDataErrorEventArgs) _ 
     Handles BindingManagerBase1.DataError

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Exception", e.Exception)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"DataError Event")

End Sub
