       dt.Rows[ctr]["selected"]=r.SelectedIndex;

        



		Session["ctr"] = ctr;

Solution 1

Their can be multiple issues with your code.

Few which I can see are as below.

1) Delcare object of RadioButtonList as below.

C#

RadioButtonList r = new RadioButtonList();

2) Use below syntax while adding Items.

C#

r.Items.Add(dt.Rows[ctr]["choice1"].ToString());

Also debug your code and check your dt is not null and has Rows in it.
