To implement what you plan you should keep the list that loads the listboxes in the object Session , then operating in memory you can move the items from one list to another

[ASP.NET] - Passing values between two GridView

In the article I implement this that I comment, only that instead of ListBox I use GridView, but the technique that you have to achieve is the same.

Retrieve the Session lists
Locate the selected value (you can help with linq)
Add to the selection list
Remove from the source list
Assign the DataSource to see the change reflected
