无法从 ListView 的 ItemTemplate 填充更新参数

我正在使用 ListView，并希望在客户端实现 ListView 项目从只读模式到编辑模式的切换。其中一些讨论在：客户端内联表单编辑

我正在尝试通过以下方法来做到这一点：

<asp:ListView ID="ListViewContactNumber" runat="server">
    <LayoutTemplate>
        <table cellpadding="0" cellspacing="0">
            <asp:PlaceHolder ID="itemPlaceholder" runat="server"></asp:PlaceHolder>
        </table>
    </LayoutTemplate>
    <ItemTemplate>
        <div class="readonly">
            <asp:Label ID="LabelType" runat="server" 
                Text='<%# Server.HtmlEncode(Eval("Name").ToString()) %>'></asp:Label>
            <a href="#" onclick="switchState(this,"edit");return false;">Edit</a>
        </div>
        <div class="edit">
            <asp:TextBox ID="TextBoxName" runat="server"
                Text='<%# Eval("Name") %>'
                MaxLength="256"
                Columns="10"></asp:TextBox>
            <asp:LinkButton ID="LinkButtonSave" runat="server"
                Text="Save"
                OnClick="LinkButtonSave_Click"></asp:LinkButton>
            <a href="#" onclick="switchState(this,"readonly");return false;">Cancel</a>
        </div>
    </ItemTemplate>
</asp:ListView>

switchState 是一个 Javascript 函数，它只是隐藏/显示带有 readonly 和 edit< 的 DIV /em> 类名。在 LinkButtonSave_Click 中，我从 TexBoxName 获取值，但它始终包含绑定的原始值，而不是在文本框中输入的编辑值。

ASP.NET 不回发文本框值是因为它位于 ItemTemplate 中，还是其他原因导致了此问题？
我可以使用中继器来完成此任务吗？

I am using a ListView and would like to implement the switch from read only mode to edit mode for a ListView item on the client side. Some of this is discussed at: Inline form editing on client side

I am trying to do this by something like:

<asp:ListView ID="ListViewContactNumber" runat="server">
    <LayoutTemplate>
        <table cellpadding="0" cellspacing="0">
            <asp:PlaceHolder ID="itemPlaceholder" runat="server"></asp:PlaceHolder>
        </table>
    </LayoutTemplate>
    <ItemTemplate>
        <div class="readonly">
            <asp:Label ID="LabelType" runat="server" 
                Text='<%# Server.HtmlEncode(Eval("Name").ToString()) %>'></asp:Label>
            <a href="#" onclick="switchState(this,"edit");return false;">Edit</a>
        </div>
        <div class="edit">
            <asp:TextBox ID="TextBoxName" runat="server"
                Text='<%# Eval("Name") %>'
                MaxLength="256"
                Columns="10"></asp:TextBox>
            <asp:LinkButton ID="LinkButtonSave" runat="server"
                Text="Save"
                OnClick="LinkButtonSave_Click"></asp:LinkButton>
            <a href="#" onclick="switchState(this,"readonly");return false;">Cancel</a>
        </div>
    </ItemTemplate>
</asp:ListView>

switchState is a Javascript function that simply hides/shows the DIVs with the readonly and edit classnames. In LinkButtonSave_Click I get the value from TexBoxName but it always contains the bound original value and not the edited value that was entered in the texbox.

Does ASP.NET not postback the textbox value because it is in the ItemTemplate or is it something else that's causing this problem?
Could I use a Repeater instead to accomplish this?
