MVVM PropertyChanged is not Component related!

What? I use many components!

ok - lets assume you have a Button on the Form and the button is labeled "Save". How do you want to handle this button?


<div style="text-align: justify;">1.) You can use this button like a web designer and after the button is pressed you can show up some hints : "Password missing", "Email missing" or whatever. So the user can press and directly see what is missing.
