Re: Intermittent Referencing Bug in ASP.NET 2.0 / VS 2005

Do you have the <%@ Reference directive at the top of Page1.aspx
referring to the other page you want to access?

The page model in asp.net 2.0 has changed from 1.1, now you have to use
a reference directive to access other aspx pages, if you need Page1
access Page2, and Page2 to access Page1, then that would create a
circular reference, in which case you can create an interface that your
page implements and then pass the interface around instead (better idea
IMO)

hope i didn't go off base there =) Just trying to point out problems I
ran into.

Hi guys!

I keep getting the following error reported by VS 2005 in my ASP.NET
2.0 web project:

"The type or namespace name 'MainPages_XXX' could not be found (are you
missing a using directive or an assembly reference?)"

The line of C# code (in the "code-behind" file) that error refers to
looks something like this:

if (Page.PreviousPage == null || !(Page.PreviousPage is MainPages_XXX))
{
//Some code....
}

For instance, the error might occur in a page called Page1.aspx (with
code behind file Page1.aspx.cs). In this page, I might refer to another
page, say Page2.aspx (code behind Page2.aspx.cs) in order to check that
the previous page was the correct type. In this particular project,
I've used folders to break up the structure of my ASP.NET pages. The
pages that are "erroring" are all in a folder called MainPages,
hence the "MainPages_" prefix, which VS 2005 has added itself. In the
cases where I get errors, both pages are in the same folder!

Closing and re-opening VS 2005 fixes the problem, but clearly, for a
large solution, that is not a viable way to get around this!

Has anyone else seen this problem? Is there a work around or a hot fix?
Is it a bad idea to refer to the type of the previous page (using
"is") in order to check how you got to the page you're on?

You help would be greatly appreciated!

Thanks in advance,

Steve.
