@Page Attributes: ClassName vs. Inherits ??

Between ClassName and Inherits, which attribute is set to specify the class
that a page uses? I would think that would be inherits. Further, the
description for ClassName is:

Specifies the class name for the page that will be dynamically compiled
automatically when the page is requested. This value can be any valid class
name but should not include a namespace.

So this is what will decidw what gets compiled? Then what is the point of
the src attribute? Are these two attributes mutially exclusive?
 
You can use ClassName to give a name to the page, when you use inline
code to define the page (using server-side script blocks).

If the server side code for the page is not defined inline, the source
can be specified in 2 ways:
- using the Inherits attribute - the code will be compiled into a DLL
before deployement. The Inherits attribute specifies which class
contains the code-behind for the given page.
- using the Src attribute - the code will be compiled dynamically at
runtime.

Hi Joshua,

Thanks for your response. Src and Inherits are much clearer. Could you give
me a scenario where you'd make use of the ClassName attribute? Would it be if
you were making a user control and wanted to be able to import the class it
generated?

You use the ClassName whn you use inline code. It works for Pages and
user controls (which use the Control directive instead of Page).

Consider a file called MyPage.aspx that contained:

<%@ Page Language="C#" ClassName="MyClassName" %>
<html>
<body>
Hello <asp:Label id="lblName" runat="server"></asp:Label>
<script runat="server">
void Page_Load(object sender, EventArgs e){
lblName.Text = "Josh";
}
</script>
</body>
</html>


This page is completely self-contained. Notice that there is no
MyPage.aspx.cs file required. All of the HTML and server-side code is
included in the single page. Since there is no C# code file, you are
not explicitly defining a class. In order to give the page's class a
name, you use the ClassName attribute.
 
Thanks for the detailed response, Josh...
