Asp.net 隐藏ListView表头以防代码隐藏

我想隐藏一列基于角色的ListView，不让代码隐藏。以下是标记和代码：

    <asp:ListView ID="lvTimeSheet" runat="server">
    <LayoutTemplate>
        <table id="TimeSheet">
            <thead>
                <tr>
                    <th id="thDelete" runat="server" Visible='<%# IsAdmin() %>'>
                         Select
                    </th>
                </tr>
            </thead>
            <tbody>
                <tr id="itemPlaceholder" runat="server" />
            </tbody>
        </table>
    </LayoutTemplate>
    <ItemTemplate>
        <tr>
            <td>
                <asp:CheckBox ID="cbMarkAsComplete" runat="server" onclick="selectMe(this)" Text=" &nbsp; Delete" />
            </td>
    </ItemTemplate>
</asp:ListView>

但该列id=“thDelete”始终可见。如何根据某些条件对代码隐藏列？感谢您的输入。

属性为runat=“server”的标记不允许包含在内。试试这个：

    <asp:ListView ID="lvTimeSheet" runat="server">
    <LayoutTemplate>
        <table id="TimeSheet">
            <thead>
<% If IsAdmin() Then %>

                <tr>
                    <th id="thDelete" runat="server">
                         Select
                    </th>
                </tr>
<% End If %>

            </thead>
            <tbody>
                <tr id="itemPlaceholder" runat="server" />
            </tbody>
        </table>
    </LayoutTemplate>
    <ItemTemplate>
        <tr>
            <td>
                <asp:CheckBox ID="cbMarkAsComplete" runat="server" onclick="selectMe(this)" Text=" &nbsp; Delete" />
            </td>
    </ItemTemplate>
</asp:ListView>

挑选

请尝试以下操作：

<LayoutTemplate>
    <table id="TimeSheet">
        <thead>
            <tr>
                <th id="thDelete" runat="server" Visible='<%# If( IsAdmin().tostring()="True", "true", "false") %>'>
                     Select
                </th>
            </tr>
        </thead>
        <tbody>
            <tr id="itemPlaceholder" runat="server" />
        </tbody>
    </table>
</LayoutTemplate>`

您确定IsAdmin函数返回的值为false吗？是的，即使我将函数更改为仅返回false，它仍然可见。

<LayoutTemplate>
    <table id="TimeSheet">
        <thead>
            <tr>
                <th id="thDelete" runat="server" Visible='<%# If( IsAdmin().tostring()="True", "true", "false") %>'>
                     Select
                </th>
            </tr>
        </thead>
        <tbody>
            <tr id="itemPlaceholder" runat="server" />
        </tbody>
    </table>
</LayoutTemplate>`
