FormView.OnPageIndexChanging Method

Raises the PageIndexChanging event.

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

protected virtual void OnPageIndexChanging(
	FormViewPageEventArgs e
)

Parameters

e
Type: System.Web.UI.WebControls.FormViewPageEventArgs
A FormViewPageEventArgs that contains the event data.

ExceptionCondition
HttpException

This method is called when the FormView control is not bound to a data source control, the paging operation was not canceled, and an event handler is not registered for the event.

The OnPageIndexChanging method is called by the FormView control to raise the PageIndexChanging event. It is generally used by control developers when extending the FormView class.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The OnPageIndexChanging method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

When overriding OnPageIndexChanging in a derived class, be sure to call the base class's OnPageIndexChanging method so that registered delegates receive the event.
