DataPager.OnLoad Method

This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Raises the Load event.

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

protected internal override void OnLoad(
	EventArgs e


Type: System.EventArgs
The event data.


A container control that implements the IPageableItemContainer interface was not found.

The OnLoad method notifies the server control that it should perform actions that are common to each HTTP request for the page that it is associated with. At this stage in the page life cycle, server controls in the hierarchy are created and initialized. View state is restored, and form controls reflect values that were posted from the client. This implementation also invokes the FindPageableItemContainer method to find the container control that implements the IPageableItemContainer interface, and it initializes the page properties.

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

The OnLoad method also enables 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 you override OnLoad in a derived class, make sure that you call the base class’s OnLoad method so that registered delegates receive the event.
