MVVM Light RelayCommand Parameters
I believe this will work:
_projmenuItem_Edit = new RelayCommand<object>((txt)=>ProjEditNode(txt));
-- EDIT --
You'll need to define your RelayCommand with the type as well:
e.g.
public RelayCommand<string> myCommand { get; private set; }
myCommand = new RelayCommand<string>((s) => Test(s));
private void Test(string s)
{
throw new NotImplementedException();
}
I don't think that RelayCommand()
has a constructor that is not empty. you're trying to pass the wrong kind of method to it.
If you want the RelayCommand to support Command Parameters, you should use RelayCommand<T>
where T can be any type of parameter. In your situation it would be RelayCommand<String>
which would accept a method with void(string) signature. (and therefor would also be strongly typed and won't use the ugly object)
