protected:
 virtual void OnSelectedIndexChanged(EventArgs ^ e);

protected virtual void OnSelectedIndexChanged(EventArgs e);

abstract member OnSelectedIndexChanged : EventArgs -> unit
override this.OnSelectedIndexChanged : EventArgs -> unit

Protected Overridable Sub OnSelectedIndexChanged (e As EventArgs)

Parameters

e: EventArgs

The event data.

Remarks

The SelectedIndexChanged event is raised when an item's Select button is clicked, after the ListView control handles the select operation. (A Select button is a button control whose CommandName property is set to "Select".) This enables you to perform a custom routine whenever this event occurs, such as updating a status label with the currently selected item.

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnSelectedIndexChanged method also enables derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

When you override OnSelectedIndexChanged(EventArgs) in a derived class, call the base class's OnSelectedIndexChanged(EventArgs) method so that registered delegates receive the event.
