LoginView.OnPreRender Method

Determines which role-group template to display, based on the roles of the logged-in user.

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

protected internal override void OnPreRender(
	EventArgs e


Type: System.EventArgs
An EventArgs object that contains the event data.

The OnPreRender method is called during the PreRender event to determine which content template to display to the user. If the Name property of the Page User property is null, the template specified in the AnonymousTemplate property is displayed; otherwise, the template associated with the user's role is displayed. If the user does not belong to a defined role group, or if you have not configured role management, the LoginView control displays the template specified in the LoggedInTemplate property. For more information about configuring role management, see Role Management Providers.

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

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