C#

 for (i = 0; i < gvSurvey.Rows.Count; i++)
            {
                RadioButton rdbtn1 = (RadioButton)gvSurvey.Rows[i].Cells[3].FindControl("rdbtn1");
                RadioButton rdbtn2 = (RadioButton)gvSurvey.Rows[i].Cells[4].FindControl("rdbtn2");
                RadioButton rdbtn3 = (RadioButton)gvSurvey.Rows[i].Cells[5].FindControl("rdbtn3");
                RadioButton rdbtn4 = (RadioButton)gvSurvey.Rows[i].Cells[6].FindControl("rdbtn4");


          //      RadioButton rdbtn1=(RadioButton) gvSurvey.Rows[i].ClientID  

                qtn_no = dtSurvey.Rows[i]["QTN_NO"].ToString();
                sqtn_no = dtSurvey.Rows[i]["SQTN_NO"].ToString();

                if (rdbtn1.Checked)
                {
                    rdbtn1.Text = "1";
                    lblMsg.Text = nominationsBiz.SaveSuggestion(ticketNo.ToString(), qtn_no, sqtn_no, rdbtn1.Text);
                }

Please Go through the following code you will find the Solutions

 //  It will be on your submit button click 
    protected void getPinCode()
    {
        foreach (GridViewRow grdRows in gvSurvey.Rows)
        {
            RadioButton rbt1 = (RadioButton)grdRows.FindControl("rdbtn1");
            RadioButton rbt2 = (RadioButton)grdRows.FindControl("rdbtn2");
            RadioButton rbt3 = (RadioButton)grdRows.FindControl("rdbtn3");
            RadioButton rbt4 = (RadioButton)grdRows.FindControl("rdbtn4");

            string Value = RadioValue(rbt1);
           //Similarly you can do for all radio button 
            if(!string.IsNullOrEmpty(Value))
            {

                lblMsg.Text = nominationsBiz.SaveSuggestion(ticketNo.ToString(), qtn_no, sqtn_no, Value);
            }

        }
    }


    protected string RadioValue(RadioButton Rbtlst)
    {
        string Value = "";

        if (Rbtlst.Checked == true)
        {
            Value = Rbtlst.Text;
        }
        return Value;
    }
