| System.Web.UI (system.web.dll) | class |
All Web Forms you create for an ASP.NET application derive implicitly
or explicitly from Page. This class, which is a
special subclass of Control, adds additional
page-specific functionality. For example, rather than simply
providing the Control.Context property, the
Page class provides the traditional built-in
objects through references like Response,
Request, and Application. The
Page class also provides properties that allow you
to use tracing (Trace and
TraceEnabled) and access all the validation
controls and information about whether their validation was
successful (Validators and
IsValid).Another useful property is IsPostBack, which you
can test in the Load event. Typically, you will
skip control initialization if this property returns
True, indicating that the page has already been
displayed and the control values will be persisted in view state. You
can also set AspCompatMode to
True so the Page will be
executed on a single-threaded apartment (STA) thread. This setting
allows the page to call other STA components, such as those you may
have developed with Visual Basic 6 (although it can hamper
performance significantly).Most Page methods are used by the ASP.NET
framework and will never be used in your code. One exception is
MapPath( ), which returns the physical path on the
server that corresponds to a specified virtual path (URL).public class Page : TemplateControl, System.Web.IHttpHandler {
