推荐答案

不知道，如果你还在寻找这个答案？

Not sure if you are still looking for an answer for this?

马克·雷德曼的回答是伟大的，如果你可以定义aspx页面选择列表，但是如果你的绑定下降下拉列表中动态显然，你不能。

Mark Redman's answer is great if you can define the select list in the aspx page, however if you bind the drop down list dynamically obviously you cannot.

我用下面实现的结果你是后（不知道全浏览器的支持，但在IE的新版本的工作）取得了成功。

I had success using the following to achieve the result you are after (not sure on full browser support but works in newer versions of IE)

foreach ( ListItem item in dropdownlist.Items )
{
    if ( [item should be disabled condition] )
    {
        item.Attributes.Add( "disabled", "disabled" );
    }
}

这会使您禁用的元素变灰。

This will render your disabled elements greyed out.
