Programmatically raise a command

Question

I have a button:

<Button x:Name="MyButton" Command="SomeCommand"/> 

Is there a way to execute the command from source? Calling the click on the button does not help:

MyButton.RaiseEvent(new RoutedEventArgs(Button.ClickEvent)); 

I mean - this does raise the event, but it does not raise the command. Is there something similar to this RaiseEvent but just for Command? If there is not - how can I instantiate ExecutedRoutedEventArgs? Is it possible?

Lastly - please do not tell me how to avoid calling the command.

Answer 1

Not sure if you mean:

if(MyButton.Command != null){     MyButton.Command.Execute(null); } 

with c#6 and later (as proposed by eirik) there is the short form:

Mybutton.Command?.Execute(null); 

Update
As proposed by @Benjol, providing the button's CommandParameter-property value can be required in some situations and the addition of it instead of null may be considered to be used as the default pattern:

Mybutton.Command?.Execute(MyButton.CommandParameter); 

Answer 2

Or if you don't have access to the UI element you can call the static command directly. For example I have a system wide key hook in App.xaml and wanted to call my play/pause/stop etc media events:

CustomCommands.PlaybackPlayPause.Execute(null, null); 

passing 2nd parameter as null will call all attached elements.
