How to load pages on demand using async and await in .NET MAUI DataGrid (SfDataGrid) ?

In this article, we will demonstrate how to load pages on demand using async and await in the .NET MAUI DataGrid.

xaml

<ContentPage.BindingContext>
    <local:OrderInfoViewModel x:Name="vm" />
</ContentPage.BindingContext>

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="70" />
        <RowDefinition Height="*" />
        <RowDefinition Height="70" />
    </Grid.RowDefinitions>

    <syncfusionControls:SfDataPager x:Name="dataPager"
                                    PageSize="20"
                                    PageCount="10"
                                    NumericButtonCount="10"
                                    UseOnDemandPaging="True"
                                    Grid.Row="2"
                                    OnDemandLoading="dataPager_OnDemandLoading" />

    <syncfusion:SfDataGrid x:Name="dataGrid"
                            HorizontalOptions="Fill"
                            ColumnWidthMode="Fill"
                            Grid.Row="1"
                            ItemsSource="{Binding PagedSource, Source={x:Reference dataPager}, Mode=TwoWay}" />
</Grid>

C#
The code below illustrates how to load pages on demand using async and await in the DataGrid.

private async void dataPager_OnDemandLoading(object? sender, OnDemandLoadingEventArgs e)
{
    var sourse = await vm.orderData.GetOrdersAsync(); 
    dataPager.LoadDynamicItems(e.StartIndex, sourse.Skip(e.StartIndex).Take(e.PageSize));
    (dataPager.PagedSource as PagedCollectionView).ResetCache();
}

Please remember to change the path according to your device’s location when setting the connection string.
