    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            RadioButton rdb = (RadioButton)e.Row.Cells[0].FindControl("RadioButton1");
            rdb.Attributes.Add("onclick", "setRadio(this)");
        }
    }

    protected void RadioButton1_CheckedChanged(object sender, EventArgs e)
    {
        //我不知道你所说的选中是什么意思，如果仅仅是GridView的SelectedIndex改变，以下代码就够了
        RadioButton rdb = sender as RadioButton;

        int index = (rdb.NamingContainer as GridViewRow).RowIndex;

        this.GridView1.SelectedIndex = index;
        InitGrid();
    }

gridview中radiobutton的使用就是上边这些代码，
