Occurs when the value of the PageIndex property changes before a paging operation.
Assembly: System.Web (in System.Web.dll)
The FormView control raises the event when a pager button (a button with its CommandName property set to "Page") within the control is clicked, but before the FormView control handles the paging operation. This allows you to provide an event-handling method that performs a custom routine, such as canceling the paging operation, whenever this event occurs.
This event is not raised when you programmatically set the PageIndex property.
Pager buttons are usually located in the pager row of a FormView control.
A FormViewPageEventArgs object is passed to the event-handling method, which allows you to determine the index of the page selected by the user and to indicate that the paging operation should be canceled. To determine the index of the page selected by the user, use the NewPageIndex property. To cancel the paging operation, set the Cancel property of the FormViewPageEventArgs object to true.
For more information about handling events, see NIB: Consuming Events.
The following example demonstrates how to use theevent to cancel a paging operation.
This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.
