combo box sort resort

I have a combo box that is being filled from a stored procedure. I need to add additional items to the box that aren't part of the stored procedure results. I'm adding them this way:

cboModel.Items.Add("89-0353")

This adds 89-0353 to the top of the list in the combo box.

The question I have is can the combo box be resorted so that the items are in ascending order?

The combobox has a sorted property try setting it to True and see if it'll do all the work for ya.
