Wpf binding not updating ui
The third and last Text Box uses the Property Changed value, which means that the source value will be updated each time the bound property changes, which it does in this case as soon as the text changes.Try running the example on your own machine and see how the three textboxes act completely different: The first value doesn't update before you click the button, the second value isn't updated until you leave the Text Box, while the third value updates automatically on each keystroke, text change etc.Registering for notification events requires extra bookkeeping code that obfuscates business logic.Update Controls is an open source library that replaces event-based data binding with automatic discovery and updating. WPF data binding requires that a bindable class implement the INotify Property Changed interface.I had a property changed event in my view model as well because I didn't realize this base view model class had one in there.

I also thought I should attach my Raise Property method and event, just in case it is of importance to my problem: Here is the event: Hi Stephen, Could you please try setting Selected Value instead of Selected Item? However, we will research further why Selected Item is not set correctly. All the best, Yana the Telerik team We finally got it figured out.
