I\'ve got a ComboBox in WPF that I\'ve mucked around with quite a lot (it has a custom template and a custom item template). I\'ve got it to the point now where it is workin
As far as I know there's no way to force standard ComboBox to behave this way by just changing a setting. So you'll have to implement your own combo box derivative for that or search for ready made 3rd party control (I believe there are plenty of them).
