Xamarin iOS - Text Changed event not showing results - ios

Question

Xamarin iOS is testing me lately. I have a form which has as Entry value for searching. This entry control has a text changed event. All works great , event executes and values passed as expected however the results dont appear on screen.
If i rotate the device, in this case and ipad, the results show. Everything in Android works as expected. Frustrating
CancellationTokenSource _cts;
private void Search_TextChanged(object sender, TextChangedEventArgs e)
{
try
{
_cts?.Cancel(); // cancel previous search
}
catch { } // in case previous search completed
ShowResults((Entry)sender);
}
private async void ShowResults(Entry entry)
{
using (_cts = new CancellationTokenSource())
{
try
{
await Task.Delay(TimeSpan.FromSeconds(1), _cts.Token); // buffer
using (UserDialogs.Instance.Loading("Loading. . ."))
{
ObservableCollection<TMDB_Movie> itemSourceCollection = new ObservableCollection<TMDB_Movie>();
MovieSearchVM context = (MovieSearchVM)BindingContext;
try
{
if (!IsPublicCollection)
{
var results = PrivateCollection.Where(x => x.Title.Contains(entry.Text));
foreach (TMDB_Movie movie in results)
{
movie.PublicCollection = true;
movie.Type = "Digital";
itemSourceCollection.Add(movie);
}
}
else
{
if (PhysicalDevice.HasInternetConnection())
{
TMDB_Request request = new TMDB_Request();
TMDB_Movies movies = await request.ByMovieName(entry.Text, CustomSettings.GetSettings().Language);
int i = 0;
foreach (var movie in movies.Results)
{
if (i < 10)
{
FanartTv tv = new FanartTv();
movie.Movieposter = await tv.GetSingleMoviePoster(movie.Id);
if (movie.Release_date != null)
{
char[] Separator = new char[] { '-' };
string[] year = movie.Release_date.Split(Separator, StringSplitOptions.None);
movie.Release_year = year[0];
}
movie.PublicCollection = true;
itemSourceCollection.Add(movie);
i++;
}
else
{
break;
}
}
}
}
context.MovieCollection = itemSourceCollection;
}
catch { }
}
}
catch { }
}
}
View Model
private ObservableCollection<TMDB_Movie> _MovieCollection = new ObservableCollection<TMDB_Movie>();
public ObservableCollection<TMDB_Movie> MovieCollection
{
get { return _MovieCollection; }
set
{
_MovieCollection = value;
RaisePropertyChanged("MovieCollection");
}
}
XAML
<Grid Style="{StaticResource StyleBaseGrid}" Grid.Row="2" HorizontalOptions="FillAndExpand" >
<SfListView:SfListView x:Name="GridMovieCollection"
ItemsSource="{Binding MovieCollection}"
ItemTemplate="{StaticResource StandardPosterTemplate}"
Margin="-5,0,0,0"
ItemSize="125"
ItemSpacing="0,0,0,0"
AutoFitMode="None"
SelectionBackgroundColor="Transparent"
ItemHolding="GridMovieCollection_ItemHolding"
ItemTapped="GridMovieCollection_ItemTapped" >
</SfListView:SfListView>
</Grid>
I have no clue why rotation solves this but i guess it updates the controls width and height properties and refreshes the screen.
Any ideas how i can force refresh the screen or if there is anything wrong with my code?
