ListView.OnSelectedIndexChanged Method

Raises the SelectedIndexChanged event.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)

protected virtual void OnSelectedIndexChanged(
	EventArgs e
)

Parameters

e
Type: System.EventArgs
The event data.

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 Raising an Event.

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 in a derived class, call the base class's OnSelectedIndexChanged method so that registered delegates receive the event.
