Well, surely you are doing some mistake. It's doable. Post important code-snippets here.

Further, use Debugger to see what's the flow and when do you loose your data.

You're adding items into the dropdown on the client, but when the postback happens, the server-side rebuilds the dropdown from the viewstate therefore the new items "vanish".

You need to either a) add the items into the dropdown on the server or b) record details of the new items when they're created on the client (in a hidden form variable probably) and when the postback occurs, use those details to add the new items on the server-side.
