I am wiring up a binding in code (NOT in XAML).
Is there any way of determining whether the binding path is valid? The obvious candidate is IsDataBound property, but this is always true even if the path is wrong.
Currently I am fudging it by supplying a fallback value and testing for that, but is there a better way?
If you don’t mind upgrading your project to Silverlight 5, check out the Silverlight 5 RC. With SL5 debugging databinding has become a breeze since it enables you to set breakpoints inside your XAML code where the binding happens.
