Changing/Updating Itemsource at Runtime about xfx.controls

[ChaseFlorell]

This is addressed in #23 if I'm reading this correctly. If you want to fully update the items source, you just set it in your code behind. If I missed something, please re-open this ticket. But I need to know more details to help.

@ChaseFlorell Thank you for helping me. I have tried and changed the complete datasource at runtime, but still suggestions are not being shown. below is the code.

Xaml
<xfx:XfxComboBox x:Name="cmbText" Text="{Binding SelectedName}"
ItemsSource="{Binding SuggestionItemSource}"
SortingAlgorithm="{Binding SortingAlgorithm}" WidthRequest="300" Threshold="9" />

ViewModel

When the text of combo box reaches 6 characters, I am recreating my suggestionItemSource. Below method is called properly and StringSuggestionItemSource is populating with new data properly.

 public void MyViewModel_PropertyChanged(object sender, PropertyChangedEventArgs e)
        {
            if (e.PropertyName == "SelectedName")
           {
                if (this.SelectedName.Length==6 )
                {
                    this.StringSuggestionItemSource.Clear();
                    StringSuggestionItemSource = new ObservableCollection<string>( 
buildPatientSearchItemSource(SuggestionItemSource));
              
            }

        }
    }

But still new suggestion are being shown :(.

StringSuggestionItemSource -> I am raising OnPropertyChanged event also when this property is updated.

Algorithm
public Func<string, ICollection, ICollection> SortingAlgorithm { get; } =
(text, values) => values
.Where(x => x.ToLower().Contains(text.ToLower())).Select(x=>x)
.OrderBy(x => x)
.ToList();
