Answer 1

It looks like you're rebinding the GridView each time you do a page load, so the user's selections will likely get overwritten anyway.

As requested.

Answer 2

How about the good old !IsPostBack for binding

protected void Page_Load()
{
    if (!IsPostBack)
    {
       // Binding code
    }
}

and using EnableViewState="true" on your GridView declaration so the data is not rebound on each page load.

Also, if you're having problems casting, you could try casting with row.Cells[1].Controls[1] as RadioButtonList instead of FindControl.
