GridView嵌套RadioButtonList的绑定问题

--------------------编程问答-------------------- 我顶我顶我顶 --------------------编程问答-------------------- 参考下

  <asp:GridView ID="GridView1" runat="server">
    <asp:TemplateField HeaderText="性别">
                        <ItemTemplate>
                            <asp:Label ID="lblSex" runat="server" Text='<%# Eval("sex") %>'></asp:Label>

                            <asp:RadioButtonList ID="rblSex" runat="server">
                            </asp:RadioButtonList>

                            <asp:HiddenField ID="id" runat="server" Value='<%# Eval("id") %>' />

                    </asp:TemplateField>
    </asp:GridView>



   protected void gvUser_RowDataBound(object sender, GridViewRowEventArgs e)

        {

            //判断是否是数据项

            if (e.Row.RowType == DataControlRowType.DataRow)

            {

                //判断是否是编辑状态或交替行

                if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)

                {

                   

                    RadioButtonList rblSex = (RadioButtonList)e.Row.FindControl("rblSex");//找到RadioButtonList

                    string id =( (HiddenField)e.Row.FindControl("rblSex")).Value;//找到关联键

                    rblSex.DataSource = xxxManager.GetXXById(id);//绑定RadioButtonList

                    rblSex.DataBind();

     

                }

            }

        }

--------------------编程问答-------------------- 是一种方法，
但是能否不在_RowDataBound里循环调用，
有没有方案支持在绑定GridView时直接将objectB.propertyA绑定给radiobuttonlist的？

参考下

  <asp:GridView ID="GridView1" runat="server">
    <asp:TemplateField HeaderText="性别">
                        <ItemTemplate>
                            <asp:Label ID="lblSex" runat="serv……

--------------------编程问答-------------------- 找到了一个折中的方案：



List<Option> Options = DataBinder.Eval(e.Row.DataItem, "Options") as List<Option>;

RadioButtonList rbl = e.Row.FindControl("rblOption") as RadioButtonList;

rbl.DataSource=Options;

rbl.DataBind();

--------------------编程问答-------------------- 目的是不再循环里调用数据库接口。
