给gridview动态生成radiobutton添加OnCheckedChanged事件

在写研究生系统审核功能的时候，有一个页面的gridview动态生成四列radiobutton，在gridview控件外有四个radiobutton分别控制这四列的全选中。那么当外面的某个全选按钮选中后，改变gridview里面的radiobutton选择，对应的全选按钮选中状况应该发生变化。为了实现该功能，须要在写好了radiobutton的OnCheckedChanged监听函数并添加到aspx页面后，再在gridview的RowDataBound事件中加入声明。

aspx页面部分代码：

 

<asp:TemplateField HeaderText="学位类别" SortExpression="gdxw">
                                    <ItemTemplate>
                                        <%# Eval("gdxw")%></ItemTemplate>
                                    <ItemStyle HorizontalAlign="Center" />
                                </asp:TemplateField>

加入声明代码以下：//给每一个RadioButton1绑定setRadio事件
        try
        {
            ((RadioButton)e.Row.FindControl("TySy")).Attributes.Add("OnCheckedChanged", "chenk_TySy");
            ((RadioButton)e.Row.FindControl("BtySy")).Attributes.Add("OnCheckedChanged", "chenk_BtySy");
            ((RadioButton)e.Row.FindControl("TyTcsy")).Attributes.Add("OnCheckedChanged", "chenk_TyTcsy");
            ((RadioButton)e.Row.FindControl("Qq")).Attributes.Add("OnCheckedChanged", "chenk_Qq");
        }
        catch (Exception)
        { }

OnCheckedChanged函数：
