One of the cool things about UWP apps is the way in which they can interact with “big Windows” apps as well as other UWP apps. What do I mean by this? Well, the easy example is dragging and dropping things into your app from either another UWP, or from a regular win32 application, likes files, from Explorer.

It can be a pain to set everything up for your app to start accepting files via drag and drop, so I’ve rolled the basic behaviour into, well, a behaviour.

The Solution

You can use the IsDropping property to change up elements in your UI. In my case, I wanted to highlight the BorderBrush of the attached Grid to show the user they were ok to drop the files there.
