A RelayCommand is a type of command which implements the Interface ICOmmand. ICOmmand is an Interface which must be implemented by all the commnad event in WPF or silverlight

Relat command requires two basic information:

1.What code should run when the command is executed (the _execute action)

2.What code should run to determine if this command can be executed (the _canExecute predicate)

Hope you have got the idea.

Hi,
ICommand can be used as WPF command. You can pass methods as parameters to the RelayCommand constructor.
