3. Commands One of the great advantages to commanding is encapsulation Silverlight 4 now came up with the support of Command Binding. Using Command binding you can easily develop your Silverlight MVVM
4. Commands are supported by only two element classes: Hyperlink and ButtonBase (although several button-like controls derive from ButtonBase). Commands work through two properties that have been added to the Hyperlink and ButtonBaseclass: Command and Command Parameter. The Command is the action that will be triggered when the button click takes place The CommandParameter is a single object that will be passed to the command, with additional information. Need to implement ICommand Interface
5. ICommand Interface ICommand interface features the following three members: Execute(object parameter) - Called whenever the command is activated. The parameter is optional. CanExecute(object parameter) - This method is called to determine whether the command can execute at the current time. The main feature of this is the command source can disable itself if its command cannot be executed. event CanExecuteChanged - The command should raise this event whenever it's ability to be executed has changed.
