# Paging in Xamarin.Forms Listview

The SfListView allows displaying paging using the [SfDataPager](http://help.syncfusion.com/cr/cref_files/xamarin/Syncfusion.SfDataGrid.XForms~Syncfusion.SfDataGrid.XForms.DataPager_namespace.html) control. It can be performed through loading data dynamically into ItemsSource of the SfListView using OnDemandLoading event for the current page by setting the [SfDataPager.UseOnDemandPaging](http://help.syncfusion.com/cr/cref_files/xamarin/Syncfusion.SfDataGrid.XForms~Syncfusion.SfDataGrid.XForms.DataPager.SfDataPager~UseOnDemandPaging.html) to `True`. By using the [SfDataPager.PageSize](http://help.syncfusion.com/cr/cref_files/xamarin/Syncfusion.SfDataGrid.XForms~Syncfusion.SfDataGrid.XForms.DataPager.SfDataPager~PageSize.html) property, you can define the number of list items to be displayed in each page.

```

    

        

    

    

        

            

        

    

    

        

            

                

                    

                

                

                    

                        

                                

                            

                            

                        

                    

                

            

            

        

    

```

```

public class SfListViewPagingBehavior : Behavior

{

    private Syncfusion.ListView.XForms.SfListView listView;

    private PagingViewModel PagingViewModel;

    private SfDataPager dataPager;

    protected override void OnAttachedTo(ContentPage bindable)

    {

        listView = bindable.FindByName("listView");

        dataPager = bindable.FindByName("dataPager");

        PagingViewModel = new PagingViewModel();

        listView.BindingContext = PagingViewModel;

        dataPager.Source = PagingViewModel.pagingProducts;

        dataPager.OnDemandLoading += DataPager_OnDemandLoading;

        base.OnAttachedTo(bindable);

    }

    private void DataPager_OnDemandLoading(object sender, OnDemandLoadingEventArgs e)

    {

        var source = PagingViewModel.pagingProducts.Skip(e.StartIndex).Take(e.PageSize);

        listView.ItemsSource = source.AsEnumerable();

    }

    protected override void OnDetachingFrom(ContentPage bindable)

    {

        listView = null;

        PagingViewModel = null;

        dataPager = null;

        base.OnDetachingFrom(bindable);

    }
