I have a weird issue, I'm building a Universal App and everything works when I'm debugging but when I run without debugging the emulator tries to open the application and then crashes.
Here is the code I know is failing:
private void MenuPage_Loaded(object sender, RoutedEventArgs e)
{
SetItemSource();
}
private async void SetItemSource()
{
MenuItems = await AppWinService.GetMenuEntriesAsync();
ItemSource = new ObservableCollection<AlphaKeyGroup<Menu>>
((AlphaKeyGroup<Menu>.CreateGroups(MenuItems,
CultureInfo.CurrentUICulture,
s => s.MenuName,
true)));
((CollectionViewSource)Resources["MenuGroups"]).Source = ItemSource;
}
Any suggestions? Thanks in advance.
Are you sure MenuItems
is coming back valid for all situations ? What happens on timeout?
Why not check for null just to be safe:
MenuItems = await AppWinService.GetMenuEntriesAsync();
if ((MenuItems != null) && (MenuItems.Any())
{
ItemSource = new ObservableCollection<AlphaKeyGroup<Menu>>(
(AlphaKeyGroup<Menu>.CreateGroups(MenuItems,
CultureInfo.CurrentUICulture,
s => s.MenuName,
true)));
((CollectionViewSource)Resources["MenuGroups"]).Source = ItemSource;
}
else
{
MessageBox.Show("Failure to get data");
}
