不确定您是否仍在寻找答案？

Mark Redman的答案是非常好的，如果您可以在aspx页面中定义选择列表，但是如果您明确地绑定下拉列表，您将无法。

我已经成功使用以下功能来实现您以后的结果（不确定是否支持完整的浏览器，但适用于较新版本的IE）

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

这将使您的残疾元素变灰。 p>

I have a dropdownlist which has several options for generating reports. Based on the type of account the user has certain options which should be visible but not selectable (as an incentive for them to upgrade).

I was wondering if anyone knew of a way to accomplish this.

The permissions are already in place i just need assistance with making certain items unselectable.

any help would be much appreciated.

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

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.

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" );
    }
}

This will render your disabled elements greyed out.
