ASP.Net：我如何禁用列表项？ [英] ASP.Net: How do I disable a ListItem?

问题描述

我遇到一个恼人的问题这可能真的很容易解决，如果你不是一个福利局像我这样...

I've come across an annoying problem that's probably really easy to solve if you're not a newb like myself...

我有一个的DropDownList 在ASP.Net，有一个列表项，要求被禁用...但我不是指启用=FALSE。而且我也不想禁用整个的的DropDownList 的，只是一个特定的列表项的。我正在谈论的是写在 HTML 为禁用=禁用，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>

任何人知道如何在ASP.Net做到这一点？

Anyone know how to do this in ASP.Net?

非常感谢。

推荐答案

您是否尝试过加入禁用= listitem元素的禁用？

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