The text description of the error that occurred during the binding operation.

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the Binding.BindingComplete 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 type Binding named Binding1. Then ensure that the event handler is associated with the Binding.BindingComplete event.

private void Binding1_BindingComplete(Object sender, BindingCompleteEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Binding", e.Binding );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "BindingCompleteState", e.BindingCompleteState );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "BindingCompleteContext", e.BindingCompleteContext );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ErrorText", e.ErrorText );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Exception", e.Exception );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Cancel", e.Cancel );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "BindingComplete Event" );
}

Private Sub Binding1_BindingComplete(sender as Object, e as BindingCompleteEventArgs) _ 
     Handles Binding1.BindingComplete

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Binding", e.Binding)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "BindingCompleteState", e.BindingCompleteState)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "BindingCompleteContext", e.BindingCompleteContext)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ErrorText", e.ErrorText)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Exception", e.Exception)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Cancel", e.Cancel)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"BindingComplete Event")

End Sub

Remarks

This property returns an empty string if no error occurred in the binding operation. It returns the value of the Exception.Message property when an exception occurs.
