I found it. I should have been retrieving the SerialNumber, then assigning the business object reference to the BindingContext property.

>I cannot get databinding to work for my WPF textbox controls. Here is a partial listing of the XAML for the form based on mmBusinessWindow. As you can see, I have set the Datacontext on the outter Stack Panel control and set the Binding Path for the Text Property on each textbox control.
