With both the Leave and the Validated events, your TextBox should not remain in focus. I've only done a little with this (just to see how it works), so I haven't actually updated the AutoCompleteStringCollection, but it still should not cause the TextBox to not lose focus.

Could you post the code you have in the Leave and/or Validated events?
