WPF MVVM: View information in the model?

If your application cares about the positioning of the UI elements it displays to the user, then I 'd say that the data defining this positioning is a very legitimate part of your Models.

If your application cares about the positioning of the UI elements it displays to the user, then I 'd say that the data defining this positioning is a very legitimate part of your Models. Don't confuse the ideal of decoupling the UI from your Models and ViewModels with real business requirements. For example, in an application like Visio you could say that the exact placement of objects in the page is a "view-only detail", and what matters is only the properties of the object and the connections between them.

However, from the user's perspective, the placement of objects in the workspace very much matters. In other words, it is part of your data model.

Great, thanks, that strengthens my point in saving this data in the model – PatrickS Mar 11 at 13:30.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
