Who can help me fix this problem.
This is my code for using SfDataGrid with UseOnDemandPaging.
using Syncfusion.SfDataGrid.XForms;
using Syncfusion.SfDataGrid.XForms.DataPager;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Xamarin.Forms;
namespace HelloSyncfusion
{
public partial class MainPage : ContentPage
{
SfDataGrid sfGrid = new SfDataGrid();
SfDataPager sfDataPager = new SfDataPager();
StackLayout parent = null;
VE_VESSEL_INFO_Repository resposity = new VE_VESSEL_INFO_Repository();
public MainPage()
{
InitializeComponent();
//sfGrid.ItemsSource = new OrderInfoRepository().OrderInfoCollection; //Setting ItemsSource to SfDataGrid
sfGrid.ColumnSizer = ColumnSizer.Star;
Grid myGrid = new Grid();
myGrid.HorizontalOptions = LayoutOptions.FillAndExpand;
myGrid.RowDefinitions = new RowDefinitionCollection
{
new RowDefinition { Height = 50 },
new RowDefinition {},
};
sfDataPager.OnDemandLoading += SfDataPager_OnDemandLoadingAsync;
sfDataPager.UseOnDemandPaging = true;
sfDataPager.PageSize = 5;
sfGrid.ItemsSource = sfDataPager.PagedSource;
myGrid.Children.Add(sfDataPager, 0, 0);
myGrid.Children.Add(sfGrid, 0, 1);
this.Content = myGrid;
}
private async void SfDataPager_OnDemandLoadingAsync(object sender, OnDemandLoadingEventArgs args)
{
//throw new NotImplementedException();
var vesseles = await resposity.GetCollection(); //List<object> --> Debug: OK, list count = 12
sfDataPager.LoadDynamicItems(args.StartIndex,vesseles.Skip(args.StartIndex).Take(args.PageSize));
sfDataPager.PagedSource.Refresh();
}
}
}
