save control state and display it after postback

[Uri]

Hi,
i built a control which contains two listbox controls and two buttons which
uses to transfer elements from one listbox to the other and back.
i used the buttons click events to transfer the selected item from one list
to the other
but when returning from the sever the lists items are gone.
how do i save the items through postback ?

How do you create those listboxes? Do you add them in the
CreateChildControls method?

yes i use the CreateChildControls method to
add all the elements in the control

They should save automatically if EnableViewState is true... you may be
overrwriting them when you do the transfer. When/where are you transferring
the items? Also, could you post the code you use to do the transfer?
