Ensure that you gridview is not reloading when the postback occurs. Ensure that your code is something like this:

protected void Page_Load(object sender, EventArgs e)
{
    If(!IsPostBack)
    {
       GridView1.DataSource = dataTable;
       GridView1.DataBind();
    }
}

When the radio button event is fired the Page_Load event is fired again but the grid won't refresh and the Clicked method will fire.

Try change your code:

RadioButtonList list= (RadioButtonList )row.FindControl("Radio");

To:

RadioButtonList list= (RadioButtonList )row.FindControl("RadioButtonList1");

As there is no control in your gridview named 'Radio'. Hope this will solve your problem.
