The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the FormatChanged 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 DateTimePicker named DateTimePicker1. Then ensure that the event handler is associated with the FormatChanged event.
private void DateTimePicker1_FormatChanged(Object sender, EventArgs e) {
MessageBox.Show("You are in the DateTimePicker.FormatChanged event.");
}
Private Sub DateTimePicker1_FormatChanged(sender as Object, e as EventArgs) _
Handles DateTimePicker1.FormatChanged
MessageBox.Show("You are in the DateTimePicker.FormatChanged event.")
End Sub
