Stop ASP.NET web control from HTML encoding output > Specifically, list items in a bulleted list

问题

I have an ASP.NET bulleted list control that is html encoding the list items.

<strong>First Name</strong> is required and must consist of letters only.

Is not resulting in "First Name" being output in bold text.

How do I stop the bulleted list control from html encoding its list item output?

The line in the web form is: <asp:BulletedList ID="bltUserDetailsErrors" runat="server"></asp:BulletedList>

Then there's an intermediate list of error messages:

userDetailsMessageList.Add(
                "<strong>First Name</strong>is required, must contain only letters, " +
                "and be no more than 50 letters.");

Which are then added to the bulleted list:

bltUserDetailsErrors.Items.Clear();
            foreach (string message in userDetailsMessageList)
            {
                bltUserDetailsErrors.Items.Add(new ListItem(message));
            }

Yes, it's definitely html encoding the output.

<li>&lt;strong&gt;First Name&lt;/strong&gt;is required, must contain only letters, and be no more than 50 letters.</li>

How do you get the bulleted list to render the <strong></strong> tags so that the text is bolded in the browser.
