This
is a new technology available with ASP.NET. Web Forms
are also Web Pages, but the difference between ordinary
Web Pages and Web Forms is that we can write programs
in Web Forms. We can use Web Forms as User Interfaces
like normal Web Pages.
The main attraction or advantage of Web Form is that you
can use any language provide with Microsoft Visual Studio.
NET, ie you can use either VB.NET, C#. NET or Jscript.
NET. So if a person is familiar with VB he can write code
in VB.NET or if another person is interested in C#. Net
he can write code in C#. NET. There is no need that he
should learn a new programming language to do programming
in ASP.NET.
Another important thing is programming in Web Form is
comparatively easy since you can drag user controls to
the Web Forms. You don't have to write extra code for
it. Visual Studio.NET provides a set of controls, which
you can use in Web Forms.
Structure
of a Web Form
Web
Forms are mainly divided into two parts. First is the
UI (User Interface) component and the Second part is
the logic part.
The UI part is called as the Web Forms page. The Web
Forms page has the static HTML and the server controls
we use. This File will have an extension ".aspx".
Next is the logic part, this consist of the code or
program which we write to interact with the Web Forms
page. This exists in a separate file and is called as
a " code-behind " file. As I told earlier
you can use either VB.NET, C#. NET or Jscript.This file
will have an extension ".aspx.vb" or ".aspx.cs".
The code-behind files in a particular project will be
compiled into a dynamic link library (.dll) file.
Below is a simple representation of Web Form.
