Finally, we define the method, which will be called on the event of the page. This allows us to bind the attribute of the control to the property of the page. We use the constructor to initialize the collection and set the DataContext property of the page to the instance of the page. Private async void Page_Loaded(object sender, RoutedEventArgs e)Īwait DatabaseConnector.LoadRecordsAsync(Items) Var descriptionOrdinal = reader.GetOrdinal("Description") Var nameOrdinal = reader.GetOrdinal("Name")

We set the value of the attribute of the to, which is the name of the container class we have just created. We bound the attribute to property, which we will define later in the file.

In the code, we added a new control with the name.

Replace the content of the file with the following XAML code: In the double-click on the file to open it.

Next, we are going to add a ListView control to the main page and define how the content of each item should be shown. Next, in the, double-click on the file to open it and replace the content of the file with the following code: namespace ListViewSQLiteĪs you can see, the class has two string properties and mimicking the structure of the database’s table.
