How to locate the source of a binding error?

Question

How can I figure out what line of xaml contains the troublesome binding When my debug output is full of lines like the following:

System.Windows.Data Error: 5

Answer 1

You can add this to every control that binds

  PresentationTraceSources.TraceLevel="High" 

And run the program in debug, the detailed binding information will appear in your Output window. It may help a bit. You can also create a pass though converter to catch an error (catches the problem some times but not always). There are no good tools for debugging XAML in general that I am aware of.
