The SfDataForm allows you to work with Prism framework. To achieve this, follow these steps: Step 1: Install the Prism Unity Forms NuGet package in your shared code project. Step 2: Inherit the App.xaml and App.xaml.cs files from PrismApplication instead of Application. XAML <prism:PrismApplication xmlns:prism="clr-namespace:Prism.Unity;assembly=Prism.Unity.Forms" xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="DataFormXamarin.App"> <Application.Resources> </Application.Resources> </prism:PrismApplication> C# public partial class App : PrismApplication
{
public App(IPlatformInitializer initializer = null) : base(initializer) { }
protected override async void OnInitialized()
{
InitializeComponent();
await NavigationService.NavigateAsync("DataFormPage");
}
protected override void RegisterTypes(IContainerRegistry containerRegistry)
{
}
}
Step 3: Add platform initializers to each cross-platform project. Create a new class that implements IPlatformInitializer and pass it to the LoadApplication method on each platform. Android public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
{
protected override void OnCreate(Bundle savedInstanceState)
{
TabLayoutResource = Resource.Layout.Tabbar;
ToolbarResource = Resource.Layout.Toolbar;
base.OnCreate(savedInstanceState);
global::Xamarin.Forms.Forms.Init(this, savedInstanceState);
LoadApplication(new App(new AndroidInitializer()));
}
}
public class AndroidInitializer : IPlatformInitializer
{
public void RegisterTypes(IContainerRegistry containerRegistry)
{
// Register any platform specific implementations
}
}
iOS public partial class AppDelegate : global::Xamarin.Forms.Platform.iOS.FormsApplicationDelegate
{
//
// This method is invoked when the application has loaded and is ready to run. In this
// Method you should instantiate the window, load the UI into it and then make the window
// Visible
//
// You have 17 seconds to return from this method, or iOS will terminate your application
//
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
global::Xamarin.Forms.Forms.Init();
SfDataFormRenderer.Init();
LoadApplication(new App(new iOSInitializer()));
return base.FinishedLaunching(app, options);
}
public class iOSInitializer : IPlatformInitializer
{
public void RegisterTypes(IContainerRegistry containerRegistry)
{
// Register any platform specific implementations
}
}
}
UWP public sealed partial class MainPage
{
public MainPage()
{
this.InitializeComponent();
LoadApplication(new DataFormXamarin.App(new UwpInitializer()));
}
}
public class UwpInitializer : IPlatformInitializer
{
public void RegisterTypes(IContainerRegistry containerRegistry)
{
// Register any platform specific implementations
}
}
Step 4: In App.xaml.cs file, register the View and respective ViewModel pages. protected override void RegisterTypes(IContainerRegistry containerRegistry)
{
containerRegistry.RegisterForNavigation<DataFormPage, DataFormViewModel>();
}
Step 5: Bind data to the DataForm’s DataObject property without mentioning the binding context. <dataForm:SfDataForm x:Name="dataForm"
LayoutOptions="TextInputLayout"
DataObject="{Binding ContactsInfo}"/>
