    Hello, I have C# Silverlight PRISM application with couple modules. I would like to ask you how to solve this situation: 

    1) Module Projects is loaded by default, when user select a project then event is fired in SelectedProject property.

            public ProjectItem SelectedProject
            {   get
                    return selectedProject;
                {   if (selectedProject != value)
                        selectedProject = value;
                        OnPropertyChanged(() => SelectedProject);

    2) user click a button "Show Tasks for Project" on a Ribbon and application is now loading a module Tasks using RegisterViewWithRegion, in constructor I'm subscribing event.

            public ProjectTasksViewModel(IEventAggregator eventAggregator)
                this.eventAggregator = eventAggregator;

    So when Tasks module is loaded none event is subscribed. Of course if I force publishing this event by selecting a project again this code will work perfectly.

    But I need to know how to do this automatically when Task module is loaded it knows what project-related tasks it should display.

    Hello Adam,

    As these questions are mostly related to the PRISM pattern, it would be better to post them in PRISM-related forums - for example in the CodePlex PRISM discussions board.

    All the best,
