在对话框中获取嵌套中继器中的值

我在从嵌套中继器内的文本框中获取新值时遇到问题。如果我将静态值输入到Text属性中，如下所示：我可以获取该值，但不能获取新值。在对话框中获取嵌套中继器中的值

<ItemTemplate> 
    <tr> 
     <td width="160"> 
      <%# Eval("index")%> 
     </td> 
     <td> 
      <%# Eval("Sex") %> 
     </td> 
     <td align="right"> 
      <button id="EditPuppy" class="open-dialog" runat="server"> 
       Rediger hvalp</button> 
      <juice:Button TargetControlID="EditPuppy" runat="server" /> 
     </td> 
     <td align="right" width="30"> 
      <asp:ImageButton runat="server" ID="DeletePuppy" CommandArgument='<%# Eval("dogid").ToString() %>' 
       OnClientClick='return confirm("Er du sikker på at du gerne vil slette denne hvalp?")' 
       OnCommand="DeletePuppy_Command" SkinID="DefaultDeleteButton" /> 
     </td> 
    </tr> 
    <div id="_Default" runat="server" class="basic-dialog" title="Basic dialog" runat="server"> 
     <asp:TextBox runat="server" ID="TextBoxPuppyName" Text="HEJ" /><!-- The textbox i am trying to get the value from --> 
     <asp:Button UseSubmitBehavior="false" runat="server" ID="ButtonPuppyName" CommandArgument="<%# ((RepeaterItem)Container.Parent.Parent).ItemIndex %> <-- Getting parent repaterid" 
      CommandName="<%# Container.ItemIndex %> <-- Getting current repeater index -->" 
      OnCommand="ButtonPuppyName_Command" Text="Opdater" /> 
    </div> 
    <juice:Dialog TargetControlID="_Default" AutoOpen="false" runat="server" /> 
</ItemTemplate>

代码隐藏：

protected void ButtonPuppyName_Command(object sender, CommandEventArgs e) { 
    int parentRepeaterItemIndex = Convert.ToInt32(e.CommandArgument); 
    int childRepeaterItemIndex = Convert.ToInt32(e.CommandName); 
    Repeater childReapter = (Repeater)RepeaterShowKuldUserList.Items[parentRepeaterItemIndex].FindControl("RepeaterShowKuldPuppyList"); 
    TextBox name = (TextBox)childReapter.Items[childRepeaterItemIndex].FindControl("TextBoxPuppyName"); 
    HttpContext.Current.Response.Write(name.Text); 
}

感谢您的帮助！记住进入中继器的工作，因为我可以得到“静态”值

我觉得你的问题是，你在呼唤repeater.DataBind（在页面加载？）尝试添加！的IsPostBack，然后绑定您的数据...

另一种选择是，视图状态=假..它应该是“真”

希望帮助，冉
