GridView.SelectedIndexChanging Event

Note: This event is new in the .NET Framework version 2.0.

Occurs when a row's Select button is clicked, but before the GridView control handles the select operation.

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

public:
event GridViewSelectEventHandler^ SelectedIndexChanging {
	void add (GridViewSelectEventHandler^ value);
	void remove (GridViewSelectEventHandler^ value);
}
/** @event */
public void add_SelectedIndexChanging (GridViewSelectEventHandler value)

/** @event */
public void remove_SelectedIndexChanging (GridViewSelectEventHandler value)

JScript supports the use of events, but not the declaration of new ones.

The SelectedIndexChanging event is raised when a row's Select button is clicked, but before the GridView control handles the select operation. This allows you to provide an event-handling method that performs a custom routine, such as canceling the selection operation, whenever this event occurs.

NoteNote

This event is not raised when you programmatically set the SelectedIndex property.

A GridViewSelectEventArgs object is passed to the event-handling method, which allows you to determine the index of the row selected by the user and to indicate that the selection operation should be canceled. To cancel the selection operation, set the Cancel property of the GridViewSelectEventArgs object to true.

For more information about handling events, see Consuming Events.

The following code example demonstrates how to use the SelectedIndexChanging event to cancel a select operation.

No code example is currently available or this language may not be supported.
