Hi guys,

I have an extensive ASP.NET web app that needs a CMS. I've been trying to use DNN for two months now and have had no end of trouble, and I've now reached the point where I think it cannot be done. 

The whole custom module system seems to assume that you have one module with only a couple of ascx controls based on CRUD functionality (view, edit etc).  So if you have a web app project with 50 non-crud aspx pages, what are you supposed to do? If you add more than one control to a module with the same type (eg View) DNN bombs out with duplicate key errors. Creating 50 folders/modules is counterproductive and just plain stupid. 

Has anyone incorporated an actual, real web app into DNN?

Kalor, you can create multiple controls with the VIEW type, but you need to define unique ControlKeys for them (view1, view 2, articlelist, articleview, etc).

Check out my DNNSimpleArticle module http://dnnsimplearticle.codeplex.com for an example of another approach. Basically having one VIEW control, and then within that control a placeholder that you load other controls into. This is a very common approach for intricate web apps.

Thanks for such a prompt reply.

So just to clarify: if you have a web app of any complexity, the only way to do it is to create a control of one of the four types, and load other controls programatically?

Not exactly. You can create as many different VIEW/EDIT/SETTINGS Controls as you want within a module. You just have to define a control key for each of those various controls you add.

I prefer to do it dynamically through placeholders in most cases which gives me more control over the page and still allows other modules to load on the same page.

Thanks. There are zillions of posts about control keys on this forum, and not one of them shows how to create one. Do I specify it in the markup somewhere?
