有谁知道在asp.net listview中隐藏列的方法？

<ItemTemplate>
    <tr>
        <td style="display:none;">
            <%# Eval("Column1") %>
        </td>
        <td>
            <%# Eval("Column2") %>
        </td>
    </tr>
</ItemTemplate>

protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)
{
    if (e.Item.ItemType == ListViewItemType.DataItem)
    {
        TableCell cell = e.Item.FindControl("Column1") as TableCell;
        cell.Visible = false;
    }
}

<ItemTemplate>
    <tr>
        <td id="Column1" runat="server">
            <%# Eval("Column1") %>
        </td>
        <td>
            <%# Eval("Column2") %>
        </td>
    </tr>
   <script>
        document.getElementById('<%= Column1.ClientID %>').style.display = 'none';
    </script>
</ItemTemplate>
