ListControl.DataSourceChanged Event

Occurs when the DataSource changes.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public event EventHandler DataSourceChanged
/** @event */
public void add_DataSourceChanged (EventHandler value)

/** @event */
public void remove_DataSourceChanged (EventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.

When you create a ListControl delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Events and Delegates.

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 System.Windows.Forms.MessageBox.Show with System.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.");
