Deleting controls on a webpage

[Dylan Parry]

Hi,

I'm writing a site, and I've have several HTML controls, such as UL
elements, that are dynamically populated via the application I'm writing
in C#.

Sometimes there aren't any list items that need to be added to the UL
element, so it's rendered as

<ul id=foo"></ul>

on the page, with no other content inside it. Obviously this isn't so
good, so I was wondering if I could delete the UL element from within my
C# code so that if it's going to be empty I just remove it from the page?

Can this be done? If so, how would I go about it?

Ah, it appears that the "Visible" property, when set to false, will do
just what I wanted. I presumed that it would simply set some CSS or
something on that element and would merely hide it rather than remove it.

Hi,
Yes, you can check when you populate the controls ( databinding?) and
if the collection has 0 elements set the Visible property to false;

Also, there is a group for ASP.NET where you can get more especific
answers.
