BindablePicker

Picker for Xamarin.Forms to ease programming MVVM paradigm by providing a bindable ItemsSource property amongs others

Usage

Unlike Xamarin.Forms.Picker the BindablePicker provides a property ItemsSource to bind a collection of objects to. If the collection is of type INotifyCollectionChanged (ObservableCollection implements this interface) then changes to the collection will be propogated to the Items property.

API

• ItemsSourceProperty (IList) Bind a list of objects that synchronize with the visual presentation
• DisplayMemberPath (string) The member of the object to display. Can be nested property expression
• DisplayMemberFunc (Func<object, string>) Func to create a custom string-representation of the objects
• SelectedItemProperty (object) The selected object (TwoWay-binding)

Issues

• Setting the SelectedIndex property before the ItemsSource property will set SelectedIndex to -1 since the Items property is empty cause coerceSelectedIndex returning -1
