If I have Categories and Products and I perform a control to get all the Products in a Category and I want to be able to access the Page_Controller of the Products in the Category page. How would I do it?

Example:

<% control getProducts %>
$ID : $Title
$Top.MyCategoryFunction
$MyProductFunction

<% end_control %>

If you are on any other page to a CategoryPage try putting a 'GetCategory()' function in your ProductPage model so that you can return the category page from within a control block. You still won't be able to access the CategoryPage_Controller though, so put the functions you need to access into the model class. Then you could do something like this:

<% control GetProducts %>
$ID:$Title
$GetCategory.CategoryModelFunction
$MyProductFunction

<% end_control %>

If you are on a Category page then $Top.CategoryFunction should work fine.
