Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the BindingSource..::.ListChanged 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 BindingSource named BindingSource1. Then ensure that the event handler is associated with the BindingSource..::.ListChanged event.

Visual Basic

Private Sub BindingSource1_ListChanged(sender as Object, e as ListChangedEventArgs) _ 
     Handles BindingSource1.ListChanged

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "ListChangedType", e.ListChangedType)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "NewIndex", e.NewIndex)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "OldIndex", e.OldIndex)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "PropertyDescriptor", e.PropertyDescriptor)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"ListChanged Event")

End Sub

private void BindingSource1_ListChanged(Object sender, ListChangedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "ListChangedType", e.ListChangedType );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "NewIndex", e.NewIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "OldIndex", e.OldIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "PropertyDescriptor", e.PropertyDescriptor );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "ListChanged Event" );
}
