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:

 

<asp:TemplateField HeaderText="学位类别" SortExpression="gdxw">
                                    <ItemTemplate>
                                        <%# Eval("gdxw")%></ItemTemplate>
                                    <ItemStyle HorizontalAlign="Center" />
                                </asp:TemplateField>
                                <asp:TemplateField HeaderText="同意" SortExpression="xwkyqxf">
                                    <ItemTemplate>
                                        <asp:RadioButton ID="TySy" runat="server" GroupName="bjyj" AutoPostBack="True" OnCheckedChanged="check_TySy" />
                                     </ItemTemplate>
                                    <ItemStyle HorizontalAlign="Center" />
                                </asp:TemplateField>
                                <asp:TemplateField HeaderText="不同意" SortExpression="zdkxxf">
                                    <ItemTemplate>
                                       <asp:RadioButton ID="BtySy" runat="server" GroupName="bjyj" AutoPostBack="True" OnCheckedChanged="check_BtySy"/>
                                        </ItemTemplate>
                                    <ItemStyle HorizontalAlign="Center" />
                                </asp:TemplateField>
                                <asp:TemplateField HeaderText="同意推迟" SortExpression="kkzyxkxf">
                                    <ItemTemplate>
                                        <asp:RadioButton ID="TyTcsy" runat="server" GroupName="bjyj" AutoPostBack="True" OnCheckedChanged="chenk_TyTcsy" />
                                        </ItemTemplate>
                                    <ItemStyle HorizontalAlign="Center" />
                                </asp:TemplateField>
                                <asp:TemplateField HeaderText="弃权" SortExpression="xwkyqcj">
                                    <ItemTemplate>
                                       <asp:RadioButton ID="Qq" runat="server" GroupName="bjyj" AutoPostBack="True" OnCheckedChanged="chenk_Qq" />
                                        </ItemTemplate>
                                    <ItemStyle HorizontalAlign="Center" />
                                </asp:TemplateField>

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)
    {
