Class Set as DataContext in XAML without Code Behind

In dealing with a problem at work and I am probably as guilty as anyone of relying on code behind to do basic functions without soley using XAML. Why? Because that’s the way I have always done it. But it’s a new day and time to learn new ways to do things. So here we go….

This example shows a class set as datacontext – the code behind file is completely empty.

Have a great week….
