.aspx 文件：

<asp:Repeater ID="Repeater_sorular" runat="server">

   </HeaderTemplate>
   <ItemTemplate>
      <div class="div_soru">

和代码隐藏：

SpAnketDataContext db = new SpAnketDataContext();

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        BindRepeaterSorular();
    }
}

protected void ImageButton_kaydet_OnCommand(object source, CommandEventArgs e)
{

}

private void BindRepeaterSorular()
{
    int anket_id = 3;

    var sorular = from soru in db.TableSurveyQuestions
                  where soru.SurveyId == anket_id
                  select new
                  {
                      soru.TypeId,
                      soru.Subject,
                      soru.QuestionId,
                      soru.SurveyId,
                      soru.QueueNo,
                      SurveyTitle = soru.TableSurvey.Title,
                      TypeName = soru.TableSurveyQuestionType.TypeName,

                      Secenekler = from secenekler in soru.TableSurveyOptions
                                   select new
                                   {
                                       secenekler.OptionId,
                                       secenekler.OptionName,
                                       secenekler.QuestionId,
                                   }
                  };

    Repeater_sorular.DataSource = sorular;
    Repeater_sorular.DataBind();
}

我的问题是：

我无法绑定 datavaluefield 和 datatextfiled。如果我按照上面的定义写。我收到这个错误。

DataBinding: '<>f__AnonymousType1`8[[System.Nullable`1[[System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]], mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Nullable`1[[System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]], mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Nullable`1[[System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]], mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Collections.Generic.IEnumerable`1[[<>f__AnonymousT...' does not contain a property with the name 'OptionName'.

如何绑定值和文本。

Thanks.

该错误本身解释得很清楚：

does not contain a property with the name 'OptionName'

只需更改此（在两者中，您的声明RadioButtonList and CheckBoxList):

DataTextField='<%#Eval("OptionName")%>' DataValueField='<%#Eval("OptionId")%>'

To:

DataTextField="OptionName" DataValueField="OptionId"

就是这样，您不需要评估绑定，只需指定属性的名称即可。其余的代码看起来不错

Edited

根据请求，从RadioButtonList:

<asp:GridView runat="server" OnRowCommand="grdProducts_RowCommand" ID="grdProducts">
    <Columns>
        <asp:TemplateField ShowHeader="False">
            <ItemTemplate>
                <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="false" 
                    CommandName="myLink" CommandArgument='<%# DataBinder.Eval(Container, "RowIndex") %>' Text="Button"></asp:LinkButton>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:TemplateField>
            <ItemTemplate>
                <asp:RadioButtonList DataTextField="NestedValue" DataValueField="ID" runat="server" DataSource='<%# Eval("Nested") %>' ID="radios">
                </asp:RadioButtonList>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

<asp:Label runat="server" ID="lblMessage" />

背后代码：

    protected void grdProducts_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        switch (e.CommandName)
        {
            case "myLink":
                var row = this.grdProducts.Rows[int.Parse(e.CommandArgument.ToString())];
                var radios = row.FindControl("radios") as RadioButtonList;
                this.lblMessage.Text += "<br/>" + radios.UniqueID;
                this.lblMessage.Text += "<br/> dedede " + radios.SelectedValue;
                break;
        }
    }
