Viewstate versus performance

If I want to create a ListBox filled by a database query, it is not
recommended to enable the viewstate of the form,
because it does not make sense to reconstruct the whole and costs
performance.
But what if I want to react on the onChange event, I do have to set
autoRepost to true to get my selectedItem.
It seems I need the viewstate to retrieve my selection.

What is the best practice to do this:
- fill list by database query
- react on change event at the client site or with minimum overhead on
server
