asp.net c# survey application retrieve values from application & insert new data to SQL and write SQL query

I am developing a small survey application that uses a multiview form with 4 checkboxlists, 2 radiobuttons, 1 dropdowns and multiple free text entry fields. I need to retrieve all of the values from all of these controls and enter them into SQL database. I have written code to insert multiple items into the database per individual control but would like to get them in all one instance instead of opening & closing each time iteration over a different type of control has stopped.
