ReactiveUI commands : How to use canexecute with static conditions

Question

How can I do this equivalently with ReactiveUI commands? And there especially deal with the IObservable equivalent CanExecute?

private readonly bool enableEdit = ctor-param;

this.AddIdCommand = new DelegateCommand(AddIdExecute, ()=>enableEdit);

Answer 1

If it is that static in value, do it like so:

this.AddIdCommand = ReactiveCommand.Create(AddIdExecute, Observable.Return(enableEdit));
