As far as I understood your question, you need to carry some information from the one ASP.NET page to another one.

There are several options to do it:

1. You can use your Session object and persist some information there:

   Session["somestring"] = somedata;

2. You can pass some parameters, like GroupID etc. to the new page either by GET (termed "query strings" in ASP.NET) or POST, here is an example how to do it: http://msdn.microsoft.com/en-us/library/6c3yckfw.aspx

3. You can register your own routes for ASP.NET application and then dynamically generate the page link to pass your data in a RESTful way. Here is some info about it: http://msdn.microsoft.com/en-us/library/cc668201.aspx
