@ Page Directive tutorials

  • The Page directive is used to specifies the attribute and values that are associated with Web Form Pages (.aspx).

  • When the compiler complies the project the page directive send command that are basically used for compiling the page.

  • Some of the attributes of the page directive is :- Code File, Buffer, Culture, Debug, Language, Inherits.

 

Syntax:

The syntax of Page directive is.

<%@ Page attribute="value" [attribute="value"...] %>

 

  • The Page directive has many possible attributes. Some of the more common attributes of the Page directive are listed in Table below.

 

Properties

Description

Async

Makes the page an asynchronous handler (that is, it causes the page to use an implementation of IHttpAsyncHandler to process requests). The default is false.

AsyncTimeOut

Defines the time-out interval (in seconds) used when processing asynchronous tasks. The default is 45 seconds. The value must be an integer.

AspCompat

When set to true, allows the page to be executed on a single-threaded apartment (STA) thread.

AutoEventWireup

Indicates whether the page's events are autowired. true if event autowiring is enabled; otherwise, false. The default is true. 

Buffer

Determines whether HTTP response buffering is enabled. true if page buffering is enabled; otherwise, false. The default is true.

ClassName

A string that specifies the name of the page class that will be dynamically compiled when the page is requested. 

ClientTarget

Indicates the target user agent (typically, a Web browser such as Microsoft Internet Explorer) for which ASP.NET server controls should render content. This value can be any valid alias as defined within the <clientTarget> section of the application's configuration file

CodeBehind

Specifies the name of the compiled file that contains the class that is associated with the page. This attribute is not used at run time.

CodeFile

Specifies a path to the referenced code-behind file for the page

CodeFileBaseClass

Specifies the type name of a base class for a page and its associated code-behind class

CodePage

Indicates the value of the encoding scheme used for the response. The value is an integer that serves as an ID for the encoding scheme.

CompilationMode

Sets whether the page should be compiled, using a string that specifies one of several enumerated options. The default value is Always, so .aspx pages are compiled by default.

CompilerOptions

A string containing compiler options used to compile the page.

ContentType

Defines the HTTP content type of the response as a standard MIME type

Culture

Indicates the culture setting for the page The value of this attribute must be a valid culture ID

Debug

Indicates whether the page should be compiled with debug symbols

 true if the page should be compiled with debug symbols; otherwise, false

Description

Provides a text description of the page. This value is ignored by the ASP.NET parser.

EnableEventValidation

Enables validation of events in postback and callback scenarios. true if events are being validated; otherwise, false. The default is true.

 

EnableSessionState

Defines session-state requirements for the page. true if session state is enabled; ReadOnly if session state can be read but not changed; otherwise, false. The default is true.

EnableTheming

Indicates whether themes are used on the page. true if themes are used; otherwise, false. The default is true.

EnableViewState

Indicates whether view state is maintained across page requests. true if view state is maintained; otherwise, false. The default is true.

EnableViewStateMac

Indicates that ASP.NET should verify message authentication codes (MAC) in the page's view state when the page is posted back from the client. true if view state should be MAC checked; otherwise,false. The default is true.

ErrorPage

Defines a target URL for redirection if an unhandled page exception occurs

Explicit

Determines whether the page is compiled using the Visual Basic Option Explicit mode. 

Inherits

Defines a code-behind class for the page to inherit.This can be any class derived from the Page class. 

Language

Specifies the language used when compiling all inline rendering (<% %> and <%= %>) and code declaration blocks within the page

LCID

Defines the locale identifier for the Web Forms page

LinePragmas

Determines whether the runtime should generate line pragmas in the source code

MaintaiScrollPositionOnPostback

Indicates whether to return the user to the same position in the client browser after postback.true if users should be returned to the same position; otherwise, false. The default is false.

MasterPageFile

Sets the path to the master page for the content page or nested master page Supports relative and absolute paths

ResponseEncoding

Indicates the name of the encoding scheme used for the HTTP response that contains a page's content.

SmartNavigation

Indicates whether the page supports the smart navigation feature of Internet Explorer 5.5 or later.true if smart navigation is enabled; otherwise, false. The default is false.

Src

Specifies a path to a source file containing code that is linked to the page

WarningLevel
