Wpf binding not updating
For views, you get the get a WPF notification that a viewmodel is about to go unused by a view.
Blend-style behaviors also have their own set of lifetime problems.
I have attempted to send a "Full Name" notify when I send 'Selected Person' notify, but it doesn't make it work either.
Then there are some problems (like this and this) where WPF leaks for you too.
Finally, there are things (this, this, this, this, this, and this) that simply perform worse than you likely expect.
Can anybody tell me why the Combo Box isn't updating when I change the First Name text?
in your View Model order to notify the View that the property has changed. Example, I have a Model within that model an object Program. In another class (in the View Model code for my program's Main Window) I was also instantiating the View Model(s), i.e.: They both inherited from a superclass and I was switching back and forth between instances showing different Views in a section of the Main Window - as per my intention.
