title: How to get combobox text after user enters a value
body: <p>I have a wpf combobox bound to a CollectionView.  It is set so the user can edit the entry in the combobox selectionbox.  When the user types a value NOT in the list, I want to grab that value to use elsewhere but I cannot figure out how to get the text entered by the user.  Online help suggested using the Text property but there is no such property.  I'm using VS2013, Framework 4.5 and VB.</p>
