title: WPF what happens when a one way bound property is manually modified
body: <p>I'm just curious. For example, if the width of a custom user control is bound to the actual width of some other usercontrol, but then the width in the usercontrol is manually changed during some event. Will the property just go out of sync? Will the binding not work correctly? or will the property just be out of sync until the next time the source property changes?</p>
