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 ManageUsers, 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.

Is there any explanation for this strange behaviour???

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!!!

But I could not understand when you said:

"XML Comments are missing in the source."

What exactly did you mean by that?? (That might help some other day)

Many pieces of the core DNN code are missing the XML style comments, that drive the Intellisense information.

In VB the comments are something like

'''

What have these XML comments got to do with whether or not you can inherit or instantize a class???

I think Mitch you did not understood my problem.

Anyways, I have posted the reason & the solution in the Third post above!!!

Thanx
