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);
