@Page Directives

@Page directives allow you to set attributes that directly affect your ASP.NET pages that end with the .aspx extension. There are 26 directives available, and you can explore the exhaustive list in the SDK at the link I provided a few paragraphs back, but Table 4.4 contains some of the more commonly used @page directives.

Buffer
As seen in the previous section on the Response object, this sets whether the Buffer is enabled or not. This is true by default and would need to be set explicitly to false.

EnableSessionState
This defines Session-State requirements for the page. If this is set to true (default) then Session-State is enabled; if false Session-State is disabled; or if ReadOnly then Session state can be read but not changed.

EnableViewState
This direct controls whether ViewState(Maintain GUI state) is maintained across page requests. It is true by default.

Explicit
Specifies whether all variables on a page must be declared using a Dim, Private, Public, or ReDim statement in Visual Basic .NET. The default is false.

Inherits
Defines a class from a code-behind page that a page should inherit. (Don't worry, this will be explained is a few short minutes.)

Language
Informs the .NET Framework of the language used for all inline(<% %>) and server-side script blocks within the ASP.NET page.

Src
This contains the name of the source file for an included code-behind page.

Trace
This indicates whether tracing is enabled or not. True is enabled; otherwise false. False is the default. Tracing is a debugging function in ASP.NET that allows you to see diagnostic and debug information about an ASP.NET page.
