Nevermind - I just needed to set it = to Me.Page

Dim ThePage As FacilitiesManagement.Interfaces.IMyWebPage = Me.Page

The saga continues..

>>>Problem with trying your interface approach is that it appears that (looking at your example) I still have to inherit my _Default page when declaring the interface (same problem).

>>If you don't have an App_Code folder already, right-click on the project and select Add ASP.NET Folder, then App_Code. Right-click on App_Code and create a new class. Let's call it Interfaces. Modify the class to include a namespace and turn it into an interface definition, ex:
>>
>>

>>namespace MyApp.Interfaces
>>{
>>    public interface IMyWebPage
>>    {
>>        void UpdateText(string newText);
>>    }
>>}
>>

>>
>>

>>Namespace MyApp.Interfaces
>>   Public Interface IMyWebPage
>>      Sub UpdateText(ByVal newText As String)
>>   End Interface
>>End Namespace
>>

>>
>>Now go back to your user control - you should be able to type: MyApp.Interfaces and see Intellisense pop-up for the IMyWebPage interface.
