Guidance from another question

After adapting to your case:

<asp:Label id="lblstarUKRollNo" style="display: block;" runat="server" Text="*" CssClass="star"/>

Then, you could make it invisible on the client side on Javascript with:

document.getElementById('lblstarUKRollNo').style.display = 'none';

In addition to what @mshsyayem above has said you have to set the display to none. and you can do it in the code-behind by using the attributes. See below.

lblstarUKRollNo.Attributes.Add("style", "display:none");

Try using jQuery - $('.someElement').attr('disabled', '');

If you set Visible property to false on a server-control it wont be rendered on the client side at all. So javascript wont be able to find it. Remove Visible property; just use css style "display:none"; later use javascript to change it as "display:block"
