Examples
The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the DataSourceChanged 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 a type that inherits from ListControl, such as a ComboBox or ListBox. Then name the instance ListControl1 and ensure that the event handler is associated with the DataSourceChanged event.
private void ListControl1_DataSourceChanged(Object sender, EventArgs e) {
MessageBox.Show("You are in the ListControl.DataSourceChanged event.");
}
Private Sub ListControl1_DataSourceChanged(sender as Object, e as EventArgs) _
Handles ListControl1.DataSourceChanged
MessageBox.Show("You are in the ListControl.DataSourceChanged event.")
End Sub
