User Controls and CodeBehind

[Marc Hoeppner]

Hi,

It may sound stupid, but this happens when you forget to compile the .cs
files first. If this is not the problem and the compile went ok, then you'd
have to check all the namespaces and files again, but I am sure you did that
already. Do you use VS.NET?

Best regards,

Hmmmm.. that sounds strange. I thought the pages are compiled when they are
first loaded. The funny thing is that when I reference the control in the
script block of the aspx page it works fine and if I load the control in the
aspx page by the just it's tag name without referencing it that also works
fine. But why can't I reference the control in the codebehind of an aspx
page? I need to be able to reference the control as I need to access some
properties inside the control. Btw, I'm not using VS.NET.

Thanks
Dave
