Multiselect checkbox in xamarin forms cross platform

Question

Below is the code I'm using for checkbox in xamarin forms, but here I'm able to select only one item, I wanted to select multiple items from the checkbox. To the checkbox the data is binded from the database. Please help me

Checkforms.xaml.cs

public partial class Checkforms : ContentPage

{

private ObservableCollection<HelperModel> statusRecords;

string[] statusList;

public Checkforms()

{

InitializeComponent();

GetUserRoles();

}

public async void GetUserRoles()

{

HttpClient client = new HttpClient();

var response = await client.GetStringAsync("http://**********/api/Masters/getRoles");

var details = JsonConvert.DeserializeObject<List<HelperModel>>(response);

ListView1.ItemsSource = details;

}

private async void ListView1_ItemSelected(object sender, SelectedItemChangedEventArgs e)

{

if (e.SelectedItem == null) return;

var statusData = e.SelectedItem as HelperModel;

((ListView)sender).SelectedItem = null;

HttpClient client = new HttpClient();

var response = await client.GetStringAsync("http://********/api/Masters/getRoles");

var details = JsonConvert.DeserializeObject<List<HelperModel>>(response);

ListView1.ItemsSource = details;

var item = details.Where(x => x.name == statusData.name).FirstOrDefault();

if (item != null)

item.IsSelected = !item.IsSelected;

}

}

HelperModel.cs

public class HelperModel : INotifyPropertyChanged

{

public event PropertyChangedEventHandler PropertyChanged;

private bool isSelected = false;

public string name { get; set; }

public bool IsSelected

{

get { return isSelected; }

set

{

isSelected = value;

OnPropertyChanged("IsSelected");

}

}

//OnProperty changed method

protected void OnPropertyChanged([CallerMemberName] string propertyName = null)

{

PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));

}

}

Thanks in advance
