Load documentview in module on demand when using Prism4

Docking/MDI for WPF Forum

I am trying to integrate the docking and MDI component into MS Prism v4 pattern.

I have tried the prism-integration sample. It works well. But I have tow questions beyound the sample.

1. I don't want the documentviews which are defined in a module to be injected into the shell during initializing. Instead of that, I would like to use a menuitem in main shell to load these documentviews and then show them in dockworkspace. How to make it happen?

2. I have no idea how to show the documentviews again after I click "X" to close them.

Can I get some advice?

Thank you.

1. To prevent the DocumentWindows from opening automatically, you'd need to use a custom DocumentWindowInitializer. Something like this should work:
public class MyDocumentWindowInitializer : DocumentWindowInitializer {

    public override void Open(DockingWindow dockingWindow, object item) {
        // TODO: Call base.Open if you want to open the window, otherwise do not call it
        base.Open(dockingWindow, item);

Then you'd use that as your initializer, instead of the default DocumentWindowInitializer. To open a specific view, you'd need to "activate" it in the DockSiteRegion. Assuming you have an instance of the RegionManager, you can get the region and activate a view like so:
// Get the DockSite region
var region = regionManager.Regions[RegionNames.MainRegion];

// Activate the view, which will open the document
2. This is the same as above, you simply activate the view.

Also, keep in mind that the full source is available for the Docking.Interop.Prism assembly, so you can see what's going on there. The code is available at http://actipro.codeplex.com.
