Call view method from viewmodel

May 27, 2012 at 9:57 PM

Hallo,

I came to a point where normal binding won't work for me. I have a third party control which offers two methods restoreLayoutFromXML/saveLayoutToXML. There is no direct way from the control to use it it mvvm style.

I thought about some solutions, but I can't decide what is the best in thinking of mvvm:

1) The simplest way: Add one event to the VM, register a handler in the view and pass the delegate.

2) Use an IView interface

3) Attached behavior

 

What way would you go?

I would go for 1. It might seem dirty, but it is still clean (view model not referencing the view) and easy to understand for other developers that read the code.

Thanks, that was my favorite.
