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情况应该发生变化。为了实现该功能，需要在写好了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：

 

                                        
     
                                              <%# Eval("gdxw")%>
                                         
                                     
                                    
                                        
                                             
                                           
                                         
                                     
                                    
                                        
                                            
                                              
                                         
                                     
                                    
                                        
                                             
                                              
                                         
                                     
                                    
                                        
                                            
                                              
                                         
                                     
    

加入声明代码如下：//给每个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：

#region 授予选择发生改变

    //同意授予发生变化     protected void check_TySy(object sender, EventArgs e)

    {
