Commands and DelegateCommand

Last updated 7 months ago

WPF and Universal Applications have a really handy way to handle the concept of a command: the ICommand interface (http://msdn.microsoft.com/library/system.windows.input.icommand.aspx).

Radical has its own implementation that allows to easily hook command logic using delegates. The Radical DelegateCommand adds a set of features on top of the default .Net ICommand.

Creating a command in Radical is as easy as:

ICommand command = DelegateCommand.Create()
.OnCanExecute( state =>
{
//command validation logic.
return true;
} )
.OnExecute( state =>
{
//command execution logic.
} );

The command entry point is the DelegateCommand class, in the above sample used in a fluent interface manner.
