How to render ListView using RealmObject in Xamarin.Forms (SfListView)

Platform: Xamarin.Forms |
Control: SfListView

You can render Xamarin.Forms SfListView using the Realm object. Please follow the steps below to use the Realm object.

Step 1: Install the Realm Nuget package to the shared code project.

Step 2:  Create a model class by inheriting RealmObject.

namespace ListViewXamarin
    public class BookInfo : Realms.RealmObject
        public BookInfo()
        public string BookName { get; set; }
        public string BookDescription { get; set; }
        public string BookAuthor { get; set; }

Step 3: Obtain the realm object in the model class repository using the GetInstance method. Populate items and add them to the Realm object.

namespace ListViewXamarin
    public class BookInfoRepository
        Realms.Realm realm;
        public BookInfoRepository()
            realm = Realms.Realm.GetInstance();
        internal IEnumerable<BookInfo> GetBookInfo()
            realm.Write(() =>
                for (int i = 0; i < BookNames.Count(); i++)
                    var book = new BookInfo()
                        BookName = BookNames[i],
                        BookDescription = BookDescriptions[i],
                        BookAuthor = BookAuthers[i],
            return realm.All<BookInfo>().AsRealmCollection();

Step 4: Create a ViewModel collection as IEnumerable and set the realm collection to the ViewModel collection.

namespace ListViewXamarin
    public class ViewModel
        private IEnumerable<BookInfo> bookInfo;
        public ViewModel()
        public IEnumerable<BookInfo> BookInfo
            get { return bookInfo; }
            set { this.bookInfo = value; }
        private void GenerateSource()
            BookInfoRepository bookInfoRepository = new BookInfoRepository();
            bookInfo = bookInfoRepository.GetBookInfo();

Step 5: Bind ViewModel collection to SfListView.ItemsSource and bind the model properties to the ItemTemplate.

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
        <local:ViewModel />
    <sync:SfListView x:Name="listView" AutoFitMode="Height" ItemsSource="{Binding BookInfo}" SelectionBackgroundColor="#d3d3d3">
                <Grid Padding="0,12,8,0">
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="1"/>
                    <StackLayout Orientation="Vertical" Padding="5,-5,0,0" VerticalOptions="Start" Grid.Row="0">
                        <Label Text="{Binding BookName}" FontAttributes="Bold" FontSize="16" TextColor="#000000" />
                        <Label Text="{Binding BookAuthor}" Grid.Row="1" FontSize="14"  Opacity=" 0.67" TextColor="#000000" />
                        <Label Text="{Binding BookDescription}" Opacity=" 0.54" TextColor="#000000" FontSize="13"/>
                    <BoxView Grid.Row="1" HeightRequest="1" Opacity="0.75" BackgroundColor="#CECECE" />
