RadioButtonList在DataList或者GridView里什么取值

先在gridview中findcontrol()，找到这个RadioButtonList控件，然后强制转换成RadioButtonList。就跟一般的RadioButtonList一样的用了。

额你有没有绑定DataList的- -~~

View Code private List<Survey> SurveyData()
    {
        List<Survey> s = new List<Survey>();
        s.Add(new Survey("1.1", "title 1"));
        s.Add(new Survey("1.2", "title 1"));
        s.Add(new Survey("1.3", "title 1"));
        return s;
    }这里是放在类里还是放在~新建的aspx里?- -刚刚入门问的问题有点内阁个~但是还是希望你能教教

protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            {
                DataTable dt = new DataTable();
                dt.Columns.AddRange(new DataColumn[] {
                    new DataColumn("name",typeof(string)),
                    new DataColumn("age",typeof(string))
                });                DataRow dr = null;                dr = dt.NewRow();
                dr["name"] = "guwei";
                dr["age"] = "30";
                dt.Rows.Add(dr);                dr = dt.NewRow();
                dr["name"] = "google";
                dr["age"] = "28";
                dt.Rows.Add(dr);                this.DataList1.DataSource = dt;
                this.DataList1.DataBind();
            }
        }        protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
        {
            RadioButtonList radioButtonList = e.Item.FindControl("RadioButtonList1") as RadioButtonList;
        }        protected void Button1_Click(object sender, EventArgs e)
        {
            foreach (DataListItem item in DataList1.Items)
            {
                RadioButtonList radioButtonList = item.FindControl("RadioButtonList1") as RadioButtonList;
                string value = radioButtonList.SelectedValue;
            }        }<body>
    <form id="form1" runat="server">
    <div>
        <asp:DataList ID="DataList1" runat="server"
            onitemdatabound="DataList1_ItemDataBound">
            <ItemTemplate>
                <asp:RadioButtonList ID="RadioButtonList1" runat="server">
                    <asp:ListItem Text="1" Value="1" />
                    <asp:ListItem Text="2" Value="2" />
                    <asp:ListItem Text="3" Value="3" />
                </asp:RadioButtonList>
            </ItemTemplate>
        </asp:DataList>
    </div>
    <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
    </form>
</body>

RadioButtonList rbl=(RadioButtonList)你的数据控件名称.rows[行号].findcontrol("你的radiolist名称")这样就获取到某一行的单选按钮了。获取这里面的值也是很简单的跟普通的一样方式

页面应该看得懂吧，后台注释如下：
protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            {
                //初始化一个Datatable
                DataTable dt = new DataTable();
                dt.Columns.AddRange(new DataColumn[] {
                    new DataColumn("name",typeof(string)),
                    new DataColumn("age",typeof(string))
                });                DataRow dr = null;                dr = dt.NewRow();
                dr["name"] = "guwei";
                dr["age"] = "30";
                dt.Rows.Add(dr);                dr = dt.NewRow();
                dr["name"] = "google";
                dr["age"] = "28";
                dt.Rows.Add(dr);                //DataList绑定这个Datatable
                this.DataList1.DataSource = dt;
                this.DataList1.DataBind();
            }
        }        //这个而是DataList1控件的ItemDataBound事件
        protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
        {
            //这里可以在DataList1绑定后，获取每一个RadioButtonList
            RadioButtonList radioButtonList = e.Item.FindControl("RadioButtonList1") as RadioButtonList;
        }        //这里是一个按钮，随意点击遍历这个DataList1的Item，来获取所选的值
        protected void Button1_Click(object sender, EventArgs e)
        {
            foreach (DataListItem item in DataList1.Items)
            {
                RadioButtonList radioButtonList = item.FindControl("RadioButtonList1") as RadioButtonList;
                string value = radioButtonList.SelectedValue;
            }        }

我有个问题能给个建议么~~？我在做一个在线考试的东西 ~学生端的~~你说用RadioButton好还是RadioButtonList好

每一道题答案都有：ABCD四个选项，还是用RadioButton好用。当然RadioButton也一样用就是了。

以前都没接触过这种~~以前都是直接用DataList或者GridView做添加修改删除~~现在第一次接触这种- -所以不知道什么下手

每一道题答案都有：ABCD四个选项，还是用RadioButton好用。当然RadioButton也一样用就是了。恩~用RadioButton 我知道用循环快~但是不知道什么下手~所以每个RadioButton 都要写一段代码

调试易

RadioButtonList在DataList或者GridView里什么取值
