That is how my RadListView is defined. And these are my handlers:
/// <summary>
/// OnRefresh method
/// </summary>
private async void listView_RefreshRequestedAsync(object sender, Telerik.XamarinForms.DataControls.ListView.PullToRefreshRequestedEventArgs e)
{
await Task.Run(() => ReloadData());
listView.IsPullToRefreshActive = false;
listView.IsLoadOnDemandEnabled = App.ShouldInfiniteScroolBeEnabled(assetsViewModel.ListOfAssets.Count);
}
/// <summary>
/// Reloads the data back to the default, remaking the API call. This will fetch the newest data.
/// </summary>
private void ReloadData()
{
assetsViewModel.PageNumber = 1;
assetsViewModel.GetAssets();
listView.ItemsSource = assetsViewModel.ListOfAssets;
SearchCollection = listView.ItemsSource as ObservableCollection<AssetsListModel>;
}
