Here, we implemented a two-click event to navigate to another page.Īfter that, create another ContentPage named RegisterPage. This page contains three visual elements. The app pages are Main Page, Login Page, Sign Up Page, Home Page. Method, which is used to check if the user exists or not.įinally, go to the UI design of the application. The deleteUser method is used to delete the specific user. If the user id already exists, it will return 'already exists.' The updateUser method is used for updating the existing user data like a forgotten user password. The AddUser method will add the new user. The GetSpecificUser method passes an id parameter to return that specific user. The GetUser method will return all users from the database. The queries are written based on LINQ methods. The Interface return DB path is stored in this SQLiteConnection. In this class, we are creating a new private SQLiteConnection. The other fields are username, password, and phone number.Īfter that, create another Helper class named UserDB.cs. The class contains five fields, the first field is Primary key and AutoIncrement. For that, go to Solution Explorer > SQliteDemo(Shared) > Right click and select Add > class and give the class name and click Create. Now, go to 'create a model' from the shared project. In the class, we add metadata code above the namespace because this class is derived for Dependency Service. The platform-specific code is given below. For that, expand SqliteLoginDemo.Android project and create a class named ISQLiteDbInterface_Android.cs and also follow the same steps for iOS to create an interface named ISQLiteDbInterface_iOS.cs. Next, we are going to create a SQLite DB path in Android and iOS. One method is called ISQLiteConnection, which will return the database path connection from native applications. and double click to open the interface class and this interface code is given below. For that, go to Solution Explorer and right click to select Add > Class and followed by select Interface and give name as ISQLiteInterface. Now, add Interface named ISQLiteInterface in Shared Project. Right-click and select "Manage NuGet Packages for the Solution." In the popup window, click navigate to the " Browse" tab and click browse "SQLite.Net-PCL" and select the following NuGet packages and select your project, then install it. In the next window, enter your application and solution name and then click the Create button to create the project.Īfter the project creation, add the SQLite Nuget Package to your project.įor that, open the Solution Explorer and select your Solution. Then, select Xamarin.Forms App and click Create. You can create a new Xamarin.Forms application by going to File > New and choose C# language. This sample project is targeted only for Android and iOS. ![]() We perform CRUD operations with SQLite DB in Xamarin.Forms and can easily store and retrieve objects from the local database. This article demonstrates how to register, login, and update the user data in SQLite.
