Partial class : where is the other parts?

[Michael]

Hi,
After creating a new Web site, there is a Default.aspx and
code-behind file Default.aspx.cs.
The class in the code-behind file is declared with partial:

public partial class _Default : System.Web.UI.Page
{
.....
}

It means the code is just a part of the class definition,
but where is the other parts of the class? I cannot find them.

Thanks!

The other part of the partial is generated by ASP.NET once it does it's on-demand
compilation of the page or once you do precompile.

Does this othe half of the partial class only ever reside in memory, or
is it persisted to disk? If so, where?

The whole thing is compiled and persisted to disk to the appropiate
app subdirectory of the "Temporary ASP.NET Files" folder,
under the .Net Framework directory.

Thanks Juan,

I'm finding this problematic for upgrades. Basically when I upgrade an
existing 1.1 page and I remove all of the control declarations (which
are usually in the hidden partial class) the compiler complains that
there is no declaration of those controls.

Any ideas?

Have you changed the page directive in the .aspx file? You need
something like...

<%@ Page Language="C#" CodeFile="MyClass.aspx.cs" Inherits="MyClass" %>

where MyClass is the name of the partial class. I just converted a whole
site like this. You need to change the class definition to be partial,
remove the control definitions from the class file and change the page
directive as above. That should be all you need.
