You can then show that image in the XAML Previewer at design time: In your iOS project, add the image to the Resources folder. In your Android project, add the image you want to show in the XAML Previewer to the Resources > Drawable folder. You can set a design time Source for images that are bound to the page or loaded in dynamically. Use this method to put a placeholder in for a custom control not supported by the XAML Previewer. In this example, the button only appears at design time. 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.
