Then you can use d: on any property on the cell, or you can use ` to bind to the string that you have specified: This is really great when we want to work on our cells, but don't have the data yet. This means that you can easily specify a design time ItemsSource on your ListView, CollectionView, CarouselView, etc. One really cool thing about using design time data is that you can also specify an Array of data. One of my favorite things to do is to see my ActivityIndicator in the previewer by setting d:IsRunning='True': I love to set the BackgroundColor all the time, but now, I can use design time data to see it only in the previewer. What is really great is that you can actually set ANY property! This is very nifty when you are trying to figure out spacing and sizing. To get design time data showing up we can simply add d: to a new Text property and assign the value. The previewer will automatically pick up any property that you set, however if you are using data binding then it will not be able to display anything. That's it, you are ready to go! Simple Properties You can of course change this, but d: is a nice and simple.

These three lines of code setup the ability to start using design time data with the magical d character. If you create a new project or page this will already be included and may even have some design time data already in there. The Xamarin.Forms leveraged the basic building blocks of design time data from WPF/UWP and added a few name spaces that you can import into your XAML to start using it.

That is where design time data comes in, allowing you to preview your data without having to run your app. Also, sometimes you don't have your ViewModel setup yet and you just want to start building a screen. Xamarin.Forms XAML Hot Reload is the future ( available today in VS 16.3 and VSM 8.3) for rapid iteration and productivity with XAML, I still sometimes find myself working on new screens or wanting to get a mockup of my UI without having to run my app. There is some really great docs that you should read through, but I will repeat the core info here. It is a really neat feature that I have been using on my live streams and in my apps. Recently in Xamarin.Forms 4.0 the team introduced an official pattern to specify design time properties, controls, or just about anything else. One of my favorite features of building applications with XAML is the ability to use design time data to preview it inside the IDE.
