Prism - composite view with single view model spanning on two regions

Question

I've search over SO but it seems I can't find anything no this.

I have a thing like this:

Where view A is a list of files, and view B navigates to a different folder (breadcrumb control). View B also features some functionality if view A has some items selected (like select all, delete) etc. So basically they are related and should be one view.

What I need is:

• either having one view span over two regions
• or having two views, but with one view model
• having navigation work, so if view A is navigated, view B is navigated too

I'm going to have more such situations over the whole app, so I'm looking for some common infrastructure for this to work. Is that possible in Prism?

Answer 1

There are a number of ways to accomplish what you want. Here is a PluralSight course showing you how to load dependent views in one region base on the what's being navigated to in another region using a custom region behavior.
