Could you specify the version of the controls you are using. I tested the first scenario, and the ListBox automatically scrolls to the transferred item, as per your request. So the problem might be the related to your particular version.
About the second question, to set the scroll back to the top, you could try the following function, which is attached to the OnClientLoad
event of the listbox:
The function binds to the click event of the "TransferAllToTheRight"
button and scrolls the second listbox back to the top. The same can be done for the button that transfers all items to the left.
All the best,
