Hello, I'm fairly new to the Silverlight and the MVVM / Prism pattern so this may be a stupid question. I have a View which has custom controls within it. These custom controls are actually Views too and have ViewModels to drive them. Currently to add these 'child' Views to the View I'm using (see Fig.1) and then in the ViewModel I ha...
In my application, I instantiate a new instance of my view in its associated viewmodel's constructor. I also have some events to subscribe to with an event aggregator. public class FooViewModel { private FooView TheView { get; set; } private IEventAggregator Aggregator { get; set; } public FooViewModel() { Aggre...
Hi I am creating sort of a "Navigation panel" (which is actually an ItemControl) for SL and using Regions to allow each module to add his link to the panel. Problem is that modules loading is inconsistent and thus order of links in the panel can change according to modules loading order. Restricting the modules order is out of the que...

I want to show a wait cursor during a time-consuming process in a Prism app I am writing. I have wired it up using a WaitCursorRequestEvent<bool> composite event. 'True' means show the wait cursor, 'false' means go back to default. The Shell subscribes to the event and processes it using the following event handler: /// <summary> /// ...
There are a lot of questions on S.O. about JavaFX vs. Silverlight vs. AIR, and now Prism is going to be released. These are four different technologies with a similar goal. I thought we could gather the main points -pros and cons- to consider one or the other in a community wiki question. Try to keep the flaming level at its lowest pos...

Hello guys, I'm in some sort of confusion: at one hand Microsoft architects and surrounding web community promote MVVM pattern for building WPF apps, but from the other hand in Prism patterns and practices they uses absolutely other design patterns - MVP, Presentation Model and Supervising Controller! And not a single example of use pure...

NB: I can't use the standard dialog as I'm not saving files to the file system so need to write something similar from scratch. So here are the main controls I have for my dialo...
