Hi all , I need your advice deciding on a new project architecture I'm going to implement. Can I use MEF and Prism side by side? Is it too complex to accomplish this? Can make the same stuff Prism does with MEF? Right now, two features Prism gives, but are not in MEF are Regions and the Event Aggregator. Can I do everything else wi...
I've got a Windows Forms control that I'm attempting to wrap as a WPF control using the WindowsFormsHost class; I would like to bind the legacy control to a view-model. Specifically, the control exposes a grid property, GridVisible, that I would like to bind a view-model to. I'm using a private, static backing field and a static, read-on...
I'm building a menu using Prism (using a trtelerik tree view with hierarchy data templates but hopefully the details don't matter) and I'm trying to set up a Click.Command on each menu items bindings that will all call the same delegate command which is defined in the view model. The menu is built up out of items which I don't really wan...

Here is the key piece of code: <navigation:Frame x:Name="FrameMain" Source="/Pages/StartPage.xaml"/> I am trying to ...
Hello, as the title already claims, I am searching for a WindowManager in PRISM. I know the RegionManager, and I found a LayoutManager which looks like a very promising project. Already tried it, and liked it. Now I added a post in the forum on the bottom of the page, basically I need something similar only for windows (not only layout...
In my Bootstrapper.cs in GetModuleCatalog, I need to specify the Module types using the typeof(ModuleType). In the example below I'm trying to load the Contact module on demand, but in order to get it into my module catalog, I need to have a reference to it in the project that holds my Bootstrapper. When I add a reference to Contact, the...
Hi, The scenario: I have a PRISM application developed in Silverlight (4), and I'm using a ASP.NET server side application to host several web-services (which, in turn, accesses WCF-services, but that's not really important here). The Silverlight application must be able to call the web services cross-domain (meaning that the web servic...

I am using Prism for a new application that I am creating. There are several lookup lists that will be used in several places in the application. Therefore it makes sense to define it once and use that everywhere I need that functionality. My current solution is to use typed data templates to render the controls inside a content control....
Hi, I'm new working with Prism with WPF, and I have a question which I can't find answer. Why it is impossible to add a window in a Region ? I can understand there's a good reason, so I will need another solution to my problem. It is quite simple, I got a LoginView (Window) which I want to appear first. For the previous reason, in my ...

I have an application which I am developing using WPF\Prism\MVVM. All is going well and I have some pleasing MVVM implementations. However, in some of my views I would like to be able to bind application settings e.g. when a user reloads an application, the checkbox for auto-scrolling a grid should be checked in the state it was last tim...
What would be the best way to implement NLog in my Prism / CAL WPF application. This might be an amateur question, I am a bit new to the whole Prism framework :) I thought about putting the reference to the NLog dll in the Infrastructure module and make a wrapper singleton class e.g. MyLogger. My thinking was to be able to have the refe...
Is this thread-safe? The EventAggregator in Prism is a very simple class with only one method. I was surprised when I noticed that there was no lock around the null check and creation of a new type to add to the private _events collection. If two threads called GetEvent simultaneously for the same type (before it exists in _events) it l...
