What I really need is to actually move the item out of listbox1 when I put it in listbox2 and do the reverse. Now I am lost how to get the darn thing to let me actually move the items from listbox1 to listbox2 and back. I tried initially to use ListBox2.Items.Remove(item) which of course didn't work because the data in listbox1 is bound to a database and now I have been spinning my wheels for a couple days looking for the best way to make this work. Any assistance someone could provide would be a HUGE help.
Thanks
