The BindingManagerDataErrorEventArgs provides the Exception that was caught in the binding process.

The following code example demonstrates the use of this type. In the example, an event handler reports on the occurrence of the 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 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 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" );
}
