Hi, attached is my main problem and I'll do my best to explain it as best I can. I am your standard Windows Forms developer and have been tasked with developing a new app using devexpress MVVM framework in Winforms. Bottom line is I'm hacking my way around it as I lack the knowledge of how to use it properly.
Now I'm looking for any resource which I simply cannot find that explains that framework top to bottom. I'm aware of the basics i.e Keep the UI dumb, put your logic in the ViewModel. Ideally what I'm looking for is an example of a parent view model that has a property that is a CollectionViewModelBase where the entities are bound to a grid control and the parent view model is responsible for maintaining that collection.
My problem is two fold - one is the problem attached and the second is it seems a near impossible task to learn this framework as the documentation is sorely lacking. Has anyone used this framework before and what helped them get up and running? Please no WPF - that's all I've ever found on this subject.
