add option

#1

I need to add/remove the items from the dropdownlists/listboxes. I tried the
following code:
document.getElementById("ListBox1").add(new Option("5","5"));
The code adds the new item for a moment (I can see it in the listbox and can
retrieve it by the code) but then the new items disappears from the listbox.

How can I fix it?

Thanks.

they will stay until you postback. you will need to recreate on the postback
render.

You are right. I already figured this out. I run this code by a button that
caused the postback.

Thank you.
