BindingManagerDataErrorEventArgs Class

Definition

Provides data for the DataError event.

public ref class BindingManagerDataErrorEventArgs : EventArgs
public class BindingManagerDataErrorEventArgs : EventArgs
type BindingManagerDataErrorEventArgs = class
    inherit EventArgs
Public Class BindingManagerDataErrorEventArgs
Inherits EventArgs
Inheritance
BindingManagerDataErrorEventArgs

Examples

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");
}
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
