<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:local="clr-namespace:ListViewXamarin"
             xmlns:syncfusion="clr-namespace:Syncfusion.ListView.XForms;assembly=Syncfusion.SfListView.XForms"
             x:Class="ListViewXamarin.MainPage" Title="ListViewPage">

    <ContentPage.BindingContext>
        <local:ContactsViewModel/>
    </ContentPage.BindingContext>

    <ContentPage.Content>
        <syncfusion:SfListView x:Name="listView" ItemSize="60" TapCommand="{Binding ShowPopup}" ItemsSource="{Binding contactsinfo}" SelectedItem="{Binding SelectedItem, Mode=TwoWay}">
            <syncfusion:SfListView.ItemTemplate >
                <DataTemplate>
                    <Grid x:Name="grid">
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="70" />
                            <ColumnDefinition Width="*" />
                        </Grid.ColumnDefinitions>
                        <Image Source="{Binding ContactImage}" VerticalOptions="Center" HorizontalOptions="Center" HeightRequest="50" WidthRequest="50"/>
                        <Grid Grid.Column="1" RowSpacing="1" Padding="10,0,0,0" VerticalOptions="Center">
                            <Label LineBreakMode="NoWrap" TextColor="#474747" Text="{Binding ContactName}"/>
                            <Label Grid.Row="1" Grid.Column="0" TextColor="#474747" LineBreakMode="NoWrap" Text="{Binding ContactNumber}"/>
                        </Grid>
                    </Grid>
                </DataTemplate>
            </syncfusion:SfListView.ItemTemplate>
        </syncfusion:SfListView>
    </ContentPage.Content>
</ContentPage>

public class ContactsViewModel : INotifyPropertyChanged
{
    public Command<object> ShowPopup { get; set; }
    public ContactsViewModel()
    {
        ShowPopup = new Command<object>(ShowPopupPage);
    }
 
    private async void ShowPopupPage(object sender)
    {
        //Setting binding context for the popup page to show the tapped item.
        var popupPage = new ListViewPage();
        popupPage.BindingContext = this;
        await PopupNavigation.Instance.PushAsync(popupPage);
    }
}
