Question

If i have a Binding which has a property path and the data source can i execute it in code, to find the value?

The path that i am trying to follow can be quite complicated, including collection lookup and multiple levels.

there is a hack :

create a content control
use BindingOperations.SetBinding()

then retrieve the content

is there a better way?

Answer 1

You can avoid using a ContentControl, and write your own very simple class that derives directly from DependencyObject, and provides a single DependencyProperty, which you can then target with the binding. Aside from that, no, there isn’t any better way – binding machinery in WPF is very much tied into the concept of dependency properties, and a binding cannot really be a “free-standing expression” that is just evaluated.
