>I create the new subclass for my web forms as above and now want to create a new web form based on my new subclass. Should I choose 'Add new Item' and choose the existing MM.Net Business web page and then just edit the partial class to be based on my new subclass as follows:
>
>

public class myNewWebPage : myBusinessWebPage
>{
>}
>

public partial class WebPage1 : myNewWebPage
{
}

The partial modifier has nothing to do with the inheritance from your custom class. It's for the Web Form designer.
