What is a code behind class in C++?

When the code-behind class is linked in a precompiled form, no language barrier hinders the development of the project and different languages can be used. The key point about the code-behind model is that you can bind a class to a page in two forms—source code and compiled assembly.

What is the code-behind model?

The code-behind model entails that a separate class file is used to hold all the code bound to the page. This class inherits from Page and constitutes the effective base class for the aforementioned dynamically generated class that represents the .aspx resource in execution.

What is purpose of code behind?

The code-behind class file is compiled so that it can be created and used as an object. This allows access to its properties, its methods, and its event handlers.

What is the main feature of code behind?

Code behind is a feature that enables you to take most of or all the code out of an ASP.NET page and place it in a separate file. The code is processed normally; the only difference is where the code is located. Visual Basic actually introduced the concept of code behind.

What are the advantages of using code behind?

The advantages brought by the code-behind model are clear and to a large extent also unquestionable. You deal with classes and integrate your own classes with the existing framework. The code and layout physical separation enable graphic designers and page developers to work on the same resource at the same time.

What is the difference between code behind and inline code?

One major point of Code-Behind is that the code for all the Web pages is compiled into a DLL file that allows the web pages to be hosted free from any Inline Server Code. Inline Code refers to the code that is written inside an ASP.NET Web Page that has an extension of .

How do you implement code behind?

You enable the ASP.NET code-behind feature by adding a couple of attributes, namely Inherits and Src, to the @ Page directive. The Inherits attribute contains the name of the code-behind class from which the current page inherits. The code-behind class can be any class derived from the Page class.

Is code that is embedded directly within the ASP.NET page?

Embedded code blocks are supported in ASP.NET Web pages primarily to preserve backward compatibility with older ASP technology. In general, using embedded code blocks for complex programming logic is not a best practice, because when the code is mixed on the page with markup, it can be difficult to debug and maintain.

What is inline code?

Source code that is written into the body of a program. It may refer to code written in the same language or another. For example, assembly language instructions can be embedded within a C program and would be considered inline code.

What is code behind model?

The code-behind model entails that a separate class file is used to hold all the code bound to the page. This class inherits from Page and constitutes the effective base class for the aforementioned dynamically generated class that represents the .aspx resource in execution. In other words, if you use code inline, the page is represented by an object derived from Page; otherwise, it will be represented by an instance of a class derived from the code-behind class.

What are the advantages of code behind?

The advantages brought by the code-behind model are clear and to a large extent also unquestionable. You deal with classes and integrate your own classes with the existing framework. The code and layout physical separation enable graphic designers and page developers to work on the same resource at the same time. The code is more readable, and easy to maintain. When the code-behind class is linked in a precompiled form, no language barrier hinders the development of the project and different languages can be used.

Why doesn't Visual Studio support inline code?

Why doesn’t Visual Studio .NET support inline code? Because as it is architected in version 2002 and 2003, it couldn’t otherwise provide Intellisense functionality. For Visual Studio to support inline code, or acting as a standalone editor for .aspx file, a complete reenginering is required—just what is announced for the next version!

What does codebehind mean in ASP.NET?

The Codebehind attribute means little (not nothing!) to the ASP.NET runtime. If you add a custom attribute to the @Page directive, the best that you can get is an exception. This doesn’t happen for the Codebehind attribute. (Read, the attribute is recognized but blissfully ignored.)

What is inline code in ASP.NET?

Using inline code means that you inject all the page-specific code in the same .aspx file with the rest of the page. Although insulated in a distinct tag—the <script runat=server> tag—the server-side code (postback and page event handlers, helper routines, code blocks) is merged with the markup. Especially for pages rich in content and functionality, this is not good news. The page loses in readability and maintainance. In addition, all inline code must be written in the same language declared for the page. The contents of the <script> tag are copied verbatim in the source code of the dynamically generated class that represents the .aspx resource in execution. This explains why the language must match.

How does the binding between a page and a class file work?

The binding between the page and the class file is indissolubly set at the page level using an attribute on the @Page directive. The runtime detects the link and builds the dynamic page representation using the code in the external file or assembly.

Can you use code behind in Visual Studio?

If you use Microsoft Visual Studio .NET to build your Web applications, you can’t just use the most effective implementation of code-behind. Visual Studio .NET doesn’t recognize and support the Src attribute. Even worse, it doesn’t let you add pages to the project containing inline code. To get along with Visual Studio .NET, you have to play by its rules. You have to store any server code for a page to a code-behind class. This class is bound to the .aspx page using the Inherits attribute and Visual Studio .NET takes care of building any necessary assembly at compile time.

What is code behind ASP.NET?

Here the code is compiled into a separate class from which the .aspx file derives. You can write the code in a separate .cs or .vb code file for each .aspx page. One major point of Code-Behind is that the code for all the Web pages is compiled into a DLL file that allows the web pages to be hosted free from any Inline Server Code.

What is inline code?

Inline Code. Inline Code refers to the code that is written inside an ASP.NET Web Page that has an extension of .aspx. It allows the code to be written along with the HTML source code using a <Script> tag.
