System.Web.UI.WebControls Namespace GridView Class
.NET Framework version 2.0
Occurs when any of the select buttons in a GridView control is clicked, but before the page changes.
[ VB ]
Public Event SelectedIndexChanging As GridViewSelectEventHandler
[ C# ]
public event GridViewSelectEventHandler SelectedIndexChanging;
[ C++ ]
public: __event GridViewSelectEventHandler* SelectedIndexChanging;
In [ JScript ], you can handle the events defined by a class, but you cannot define your own.
The SelectedIndexChanging event is raised whenever any of the select buttons in a GridView control is clicked, but before the GridView handles the paging 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.
NOTE: This event is not raised when the SelectedIndex property is set programmatically.
The method assigned to handle the event is passed an argument of type GridViewSelectEventArgs object containing data related to this event. The following GridViewSelectEventArgs properties provide information specific to this event.
