Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the CurrencyManager.ItemChanged 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 CurrencyManager named CurrencyManager1. Then ensure that the event handler is associated with the CurrencyManager.ItemChanged event.

private void CurrencyManager1_ItemChanged(Object sender, ItemChangedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Index", e.Index );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "ItemChanged Event" );
}

Private Sub CurrencyManager1_ItemChanged(sender as Object, e as ItemChangedEventArgs) _ 
     Handles CurrencyManager1.ItemChanged

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

End Sub
