Add multiple radiobuttons and radiobuttons groups dynamically

I have a Datalist containing many items, including "blockID" and a "blockName".

I want to populate radiobuttonlists which their value/text will be the "blockName" property, and I need them to be grouped by the "blockID" property. i.e. the user can choose only one "blockName" from each "blockID".

I need to create dynamically group of radiobuttons according to the "blockID".

I am using c# Is that possible? Thanks for any help!
