            dt.Columns.AddRange(new DataColumn[3] { new DataColumn("Id"), new DataColumn("Name"), new DataColumn("Country") });
            dt.Rows.Add(1, "John Hammond", "United States");
            dt.Rows.Add(2, "Mudassar Khan", "India");

    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Attributes["onclick"] = Page.ClientScript.GetPostBackClientHyperlink(GridView1, "Select$" + e.Row.RowIndex);
            e.Row.Attributes["style"] = "cursor:pointer";
        }
    }


    protected void OnSelectedIndexChanged(object sender, EventArgs e)
    {
        this.RadioButtonList1.Items.Clear();
        int index = GridView1.SelectedRow.RowIndex;
        for (int i = 0; i < GridView1.SelectedRow.Cells.Count; i++)
        {
            this.RadioButtonList1.Items.Add(new ListItem(GridView1.SelectedRow.Cells[i].Text, GridView1.SelectedRow.Cells[i].Text));
        }        
    }

using System.Data;

If you get the error of invalid postback then add

EnableEventValidation="false"

in your page directive.
