Question

I’m trying to learn MVVM and as a new person without a tutor, sometimes it gets sooo confusing. right now I have this problem:

** in one window, I have used 3 different views from different modelviews.
** each view is for selecting one item from a branch and we will traverse the tree.
** in first View, I choose my book
** the 2nd view will show pages of that book
** the last view I want it to show exercises of that page.

so far I was able to bind the 1st view to the Books. now, how should I bind the second view’s source to the 1st one’s slectedItem ?

Answer 1

OK I want to thank anyone who read this and tried to help, Specially yo guys “Blindmeis, Jen H”

thank you.

I know this scenario had to be so general, I just couldnt find it.

so I found 2 approaches to it that both can be good solutions.

1. Use Microsoft Prism. (Its a pattern to make modular programs in WPF with ease)
   MSDN LINK
   Another LINK

2. Use Master Detail Pattern
   Here it is clear

So I got mine solved. Hope it would be useful for you too.
