Gridview中实现RadioButton单选效果

<asp:TemplateField ItemStyle-Width="22px">

                       </asp:TemplateField>

               RadioButton rb = (RadioButton)e.Row.FindControl("radButtonControl");
               if (rb != null)
                   rb.Attributes.Add("onclick", "onRadiobuttonClick(‘" + this.gvWorkPlanList.ClientID + "‘,‘" + rb.ClientID + "‘)");
