我从嵌套中继器内的文本框中获取新值时遇到问题。如果我像这样在 Text 属性中键入静态值：我可以获取该值，但不能获取新值。

<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);
}

谢谢你的帮助！。记住进入中继器工作，因为我可以获得“静态”值

我认为您的问题是您正在调用repeater.DataBind（在页面加载中？）尝试添加 !IsPostBack 然后绑定您的数据...

另一个选项是 viewState=false.. 它应该是“true”

希望有帮助，冉
