wpf WPF Behaviors
Introduction
WPF behaviors allow a developer to alter the way WPF controls acts in response to system and user events. Behaviors inherit from the
Behavior class of the System.Windows.Interactity namespace. This namespace is a part of the overarching Expression Blend SDK, but a lighter version, suitable for behavior libraries, is available as a [nuget package][1]. [1]: https://www.nuget.org/packages/System.Windows.Interactivity.WPF/
