Needing webcontrol ideas

Question

I have a form within a CRM with very minumal space to do much so I want to use a mini website (minus the web server) that just loads dynamic data with in code.

I could write all the HTML within the methods but that its very messy.  I could create page templates and the open and manipulate them within C# and then load them into the webcontrol.  I don't know really the best way to tackle this.

Any advise would be great!

Thanks,  Corey
