GridView::SelectedIndexChanging Event

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);
}
<asp:GridView OnSelectedIndexChanging="GridViewSelectEventHandler" />

The SelectedIndexChanging event is raised when a row's Select button is clicked, but before the GridView control handles the select operation. This enables 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 enables 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 example demonstrates how to use the SelectedIndexChanging event to cancel a select operation.
