Commands for Controls Without a Command Property
Problem
Current controls may not always provide a Command property to bind to an ICommand in XAML. This can make it difficult to invoke commands in response to user interactions such as when a TextBox/PasswordBox enter key is pressed, a ListViewBase's ItemClick is fired, NavigationView.ItemInvoked, or an ItemsRepeater item is tapped.
Solution
The CommandExtensions class in the Uno Toolkit provides Command/CommandParameter attached properties for common scenarios.
PasswordBox Enter Key
<PasswordBox x:Name="LoginPassword"
utu:InputExtensions.ReturnType="Done"
utu:CommandExtensions.Command="{Binding Login}"
Tip
Usage on TextBox/PasswordBox will also cause the keyboard dismiss on enter. Similar to the InputExtensions.AutoDismiss behavior, which is explained in the InputExtensions documentation.
ItemsRepeater Item Tapped
<muxc:ItemsRepeater ItemsSource="{Binding Data}"
utu:CommandExtensions.Command="{Binding Parent.CategorySearch}">
