I am new to ASP.NET but I believe a way to implement a tab control with ASP.NET would be to have a master page with all the tabs, and then have all the pages that are going to be on the tabs linked to the master page. When you select a tab, have it load the appropriate page. This is how I am doing it currently on the web page I am building.
Another way that I think you could do it is with HTML frames.
As I said I am new to ASP.NET so these are just my ideas on how it could be done. I would be interested to see what a more experienced ASP.NET developer would say.
