The viewmodel contains code associated with that ICommand property that is executed when the button is clicked. To use the command interface, you define a data binding that targets the Command property of the Button where the source is a property in the viewmodel of type ICommand. To allow a data binding between a Button and a viewmodel, the Button defines two properties: Data bindings are defined between these commands and the Button. The viewmodel can contain commands, which are methods that are executed in reaction to a specific activity in the view such as a Button click. The commanding interface provides an alternative approach to implementing commands that is much better suited to the MVVM architecture. These commands are generally signaled by button clicks or finger taps, and traditionally they are processed in the code-behind file in a handler for the Clicked event of the Button or the Tapped event of a TapGestureRecognizer.

'At times witty, at times gritty, Dave Lewis has produced a fascinating collection on human connection. "The Voice", is for real here and poetry is back where it belongs, right there at the heart of the matter.' - John Evans Sadly, therefore, not likely to be very popular with the Arts Council aficionados, but speaking and reaching out to all those that really count. This book of verse is polemical, confessional, a slap in the face wake-up call, and a much needed challenge to all "those up there" who should have, and could have made it better. Very apt in our Twitter-twatter, X-Box-Factor age when apathy, indifference, and resignation is the norm and the - increasingly - lost generation slumber party away their lives wearing Onesies.
