IntelliSense shows squiggly lines under my design time data Troubleshooting Requirementsĭesign time data requires a minimum version of Xamarin.Forms 3.6. Refer to James Montemagno's blog post on adding design-time data to see how to bind to a static ViewModel in XAML. If you don't want to add design time data to individual controls, you can set up a mock data store to bind to your page. The benefit here is that you can bind to the actual model that you plan to use. To use the class in XAML you will need to import the namespace in the root node: xmlns:models="clr-namespace:Monkeys.Models" For example, public properties of a Monkey data object can be constructed as design time data: namespace Monkeys.Models You can also create an array of data objects. You can change x:String to an existing data model in your project. This example will show a ListView of three TextCells in the XAML Previewer. The XAML Previewer displays what is in that array in your ListView at design time. To use design time data with them, you have to create a design time array to use as an ItemsSource. However, they're difficult to visualize without real data. ListViews are a popular way to display data in a mobile app. You can then show that image in the XAML Previewer at design time: In your iOS project, add the image to the Resources folder.

You can even add it to the control itself: You can use d: with any attribute for a Xamarin.Forms control, like colors, font sizes, and spacing. Instead, it shows "Name!" where the label will have real data at runtime. In this example, without d:Text, the XAML Previewer would show nothing for the label. Elements with d: aren't shown at runtime.įor example, you can add text to a label that usually has data bound to it. To get started, add the following lines of code to the header of your XAML page: xmlns:d=""Īfter adding the namespaces, you can put d: in front of any attribute or control to show it in the XAML Previewer.
