Wpf binding not updating
To use the value converter, reference the namespace of the assembly that contains the converter and add an instance of it to the resources of your window.Now add the converter to your problematic data binding.The general idea is that your code which handles application logic, business rules, etc.gets placed into View Model classes, and all visual widgets/controls get placed into XAML views.If you examine the view model in the debugger, the Text Box Text is “Hello, world! Every other edit is ignored and causes its changes to revert, as expected.and therefore appends a message in the dispatcher's event queue.When it breaks, it can be frustrating to figure out what went wrong.In this post, I will give you some tips on how you can debug your data bindings in WPF.
I’d like to share a really awesome bit of code that I’ve been using in my XAML applications for a while now…This way, we can unit test our View Models thoroughly, and (sometimes) allow UX designers to dictate the XAML layout directly. As we dig a little more deeply into the mechanisms of data binding, we learn that part of the “magic” is achieved by way of the INotify Property Changed interface (which includes only one thing – an event named Property Changed).
