Single Radio Button check at a time in aspx

Hello Experts,

I need to create a form with radiobuttons for various fields. How can I select Single Radio Button check at a time in aspx coding and for the checked radio button I need to write a query as I have different conditions and generate a report based on that conditions. LIKE that I need to write a query for selected radio button and get fields displayed in a gridview based on that conditions.
