WinRT Event Helpers

Contains attached properties to allow certain events to be bound to a command, allowing a more MVVM pattern rather than having to subscribe to the event and create code behind.

Whilst this can be done with behaviours, the syntax is overly verbose and uses strings to find the event name; using extension methods allows a more type-safe way of subscribing to the events and a simplified syntax.

At the moment just the SearchBox is targeted, however, the framework can easily be expanded to allow events on other controls to be handled.

Example

<SearchBox events:SearchBoxQuerySubmitted.Command="{Binding QuerySubmitted}"
           events:SearchBoxSuggestionsRequested.Command="{Binding SuggestionsRequested}"
           events:SearchBoxSuggestionsRequested.Source="{Binding Suggestions}"
           QueryText="{Binding QueryText, Mode=TwoWay}" />

Extending

Additional events can easily be extended, see the SearchBoxQueryChanged class for a simple example that can be used as a template.
