Question

I have a MainWindowView(Window) with a Canvas in which I add my Views(UserControls).

The Canvas in the MainWindow is a Custom Canvas derived from Canvas so that Views inside this can be moved here and there, and can bringtofront or sendback.

I add Views to MainWindowView’s Canvas by Binding a Command to a Button. So when I click a Button, a View gets added in the Canvas.

But, my problem is, I want to add another View to the same Canvas of MainViewModel from the ViewModel of my Views which are already in the Canvas of MainViewModel.

Since the ObservableCollection, which I used to bind Canvas, is in MainViewModel, I can add View from the MainViewModel only.

When I try to use the MainViewModel from other ViewModel, I have to create a new object of it, which makes the old View in the Canvas being replaced by the new one.

Is there a solution for this. If not what’s the use of using MVVM framework.
Please help…
