ASP.NET Web Pages - Objects

Web Pages is much often about Objects.

The Page Object

You have already seen some Page Object methods in use:

@RenderPage("header.cshtml")

@RenderBody()

In the previous chapter you saw two Page Object properties being used (IsPost, and Request):

If (IsPost) {

if (Request["Choice"] != null) {

Some Page Object Methods

Method	Description
href	Builds a URL using the specified parameters
RenderBody()	Renders the portion of a content page that is not within a named section (In layout pages)
RenderPage(page)	Renders the content of one page within another page
RenderSection(section)	Renders the content of a named section (In layout pages)
Write(object)	Writes the object as an HTML-encoded string
WriteLiteral	Writes an object without HTML-encoding it first.

Some Page Object Properties

Property	Description
IsPost	Returns true if the HTTP data transfer method used by the client is a POST request
Layout	Gets or sets the path of a layout page
Page	Provides property-like access to data shared between pages and layout pages
Request	Gets the HttpRequest object for the current HTTP request
Server	Gets the HttpServerUtility object that provides web-page processing methods

The Page Property (of the Page Object)

The Page property of the Page Object, provides property-like access to data shared between pages and layout pages.

You can use (add) your own properties to the Page property:

Page.Title
Page.Version
Page.anythingyoulike

The pages property is very helpful. For instance, it makes it possible to set the page title in content files, and use it in the layout file:

Home.cshtml

@{
Layout="~/Shared/Layout.cshtml";
Page.Title="Home Page"
}

<h1>Welcome to W3Schools</h1>

<h2>Web Site Main Ingredients</h2>

<p>A Home Page (Default.cshtml)</p>
<p>A Layout File (Layout.cshtml)</p>
<p>A Style Sheet (Site.css)</p>

Layout.cshtml

<!DOCTYPE html>
<html>
<head>
<title>@Page.Title</title>
</head>
<body>
@RenderBody()
</body>
</html>
