[Mono-list] ASP Server.Transfer error

Thu May 25 23:51:37 EDT 2006

Hi,

I'm trying to run the code from MS's web site on the topic "Passing
Server Control Values Between Pages".

When I click on the "Go to second page" button, the runtime barfs with
an error "System.InvalidCastException: Cannot cast from source type to
destination type".

I'm assuming it's the line of code:

fp = (FirstPageClass) Context.Handler;

Can someone tell me if these examples should work ? Below is the code
and info on the version of Mono I'm using.

Thanks,

Bryan
