I was trying to customize the management of users by creating a module. When I tried to inherit from

DotNetNuke.Modules.Admin.Users.ManageUsers

I noticed that the class is not listed in IntelliSense. Other classes in The same namespace (like BulkEmail, Profile etc.) were listed, but MandgeUsers, MemberServices, ViewProfile etc. were not listed.

I checked Object Browser, and same was the case there. I checked definition of each class, and found no difference regarding Visibility specifiers.Each class was declared as:

Partial Class ClassName

There was nothing related to Public or Friend constructors even.

Can somebody explain this strange behaviour???

But then, Membership, Password, User etc. are also partial classes inherited by their respective ascx controls.

My question is why is that Membership & Password are available for inheritance & even object creation via New operator, but ManageUsers is available for none, when there is no difference with visibility, etc. of these partial classes???

Ok, I found the reason for that behaviour.

Only those controls' code-behind classes were available for sub-classing or creating an object, which were either referenced (<% Reference %>) or Registered (<% Register %>) in the markup for your control!!!

And that appears obvious now. As ASP.NET documentation says, these tags lead another ASP.NET page or control to be compiled with the current one. Thanx for taking time to reply!!!
