I've tried the initial task using the syntax both you and Steve recommended,
however, either way I get compile-time errors, the message of which is
something like:
'System.Web.UI.Page' does not contain a definition for 'myPublicVariable'

It makes sense that such compile-time errors would occur, as the user
control - at compile time - does not know which aspx page will be hosting
it, and the compiler therefore cannot know where to look to see if the
public property exists. Am I confused? Is it possible to do this without
getting the compile-time error and I'm just missing something.

Thanks.
