GridView::PageIndexChanging Event

Occurs when one of the pager buttons is clicked, but before the GridView control handles the paging operation.

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

public:
 event GridViewPageEventHandler^ PageIndexChanging {
	void add (GridViewPageEventHandler^ value);
	void remove (GridViewPageEventHandler^ value);
}
<asp:GridView OnPageIndexChanging="GridViewPageEventHandler" />

The PageIndexChanging event is raised when one of the pager buttons is clicked, but before the GridView control handles the paging operation. This enables you to provide an event-handling method that performs a custom routine, such as canceling the paging operation, whenever this event occurs.

NoteNote

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

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

For more information about handling events, see Consuming Events.

The following example demonstrates how to use the PageIndexChanging event to cancel the paging operation if the user attempts to navigate to another page when a GridView control is in edit mode.
