You're going to have to expand upon your question so I can have some more information.  When you say "parameterized view" do you mean a table-valued function, or a regular view where you supply a WHERE clause when querying it?  And by grouping, do you mean placing a GROUP BY clause on your query placing header rows for groups of data that is similar?

I want to create a simple web information page based on a view that I want to set a parameter for (one parameter for the entire view ) after wich I want to group the data on a web page that is all I want to do can you give me a steb by step on how can I do that ?
