如何禁用ListItem？ [英] How do I disable a ListItem?

问题描述

我在ASP.NET中有一个 DropDownList ，其中有一个 ListItem 需要禁用...但我不是说 Enable = False 。而且我也不想禁用整个 DropDownList ，只禁用一个特定的 ListItem 。我说的是用 HTML 写为 disabled = disabled ，就像这样：

I've got a DropDownList in ASP.NET that has a ListItem that requires being disabled... but I DON'T mean Enable="False". And I also don't want to disable the entire DropDownList, just one specific ListItem. What I'm talking about is written in HTML as disabled="disabled", like so:

<option disabled="disabled" value="-1">Disabled Option</option>

有人知道如何在ASP.NET中执行此操作吗？

Anyone know how to do this in ASP.NET?

推荐答案

您是否尝试过在ListItem元素上添加 disabled = disabled ？

Have you tried adding disabled="disabled" on the ListItem element?

<asp:DropDownList runat="server" ID="id">
    <asp:ListItem Text="Test" Value="value" disabled="disabled" />
</asp:DropDownList>
