BaseValidator.OnPreRender Method

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

Raises the PreRender event.

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

protected internal override void OnPreRender(
	EventArgs e
)

Parameters

e
Type: System.EventArgs

A System.EventArgs that contains the event data.

This method has been overridden to check the client browser and configure the validation control for compatibility prior to rendering.

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.
