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

| 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) |

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 Noidatut</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>
