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>
Anyone know how to do this in ASP.NET?

Use the . disabled class in Bootstrap to disable a list item in a list group in Bootstrap.
Learning jQuery In this post, I will show you how you can disable specific items of the DropDown/ComboBox/Select element using jQuery. To disable any item, just need to add attribute "disabled" with value "disabled" to the list item.
The drop-down is used to create a list of items that need to select an element. We use <select> and <option> elements to create a drop-down list and use disabled attribute in <select> element to disable the drop-down list element.
If you are creating dropdown in code behind and want to disable it in code behind only, then you should use "Enabled" property and set it to false.
You could try setting the attribute from code behind, that way you can programmatically decide what value to be set.
So in your example you would do something like this:
var listItem = DropDownList.Items.FindByText("Your Item Text");
listItem.Attributes["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>
