  • How to remove all views in region in CompositeWPF/Silverlight

    - by Dan
    Hi. I want remove all views from my region in Composite. I'm using Silverlight 4.0. And unfortunately, this code crashes with OutOfRangeException inside Composite. List<object> views = new List<object>(_regionManager.Regions["NavigationRegion"].Views); foreach (object view in views) { _regionManager.Regions["NavigationRegion"].Remove(view); } This is my callstack: [External Code] Microsoft.Practices.Composite.Presentation!Microsoft.Practices.Composite.Presentation.Regions.ViewsCollection.OnCollectionChanged(System.Collections.Specialized.NotifyCollectionChangedEventArgs e = {System.Collections.Specialized.NotifyCollectionChangedEventArgs}) Line 102 + 0x24 bytes C# Microsoft.Practices.Composite.Presentation!Microsoft.Practices.Composite.Presentation.Regions.ViewsCollection.RemoveAndNotify(System.Collections.IList items = Count = 1) Line 45 + 0x2b bytes C# Microsoft.Practices.Composite.Presentation!Microsoft.Practices.Composite.Presentation.Regions.ViewsCollection.UnderlyingCollection_CollectionChanged(object sender = Count = 0, System.Collections.Specialized.NotifyCollectionChangedEventArgs e = {System.Collections.Specialized.NotifyCollectionChangedEventArgs}) Line 153 + 0xb bytes C# [External Code] Microsoft.Practices.Composite.Presentation!Microsoft.Practices.Composite.Presentation.Regions.Region.Remove(object view = {Kite.MyApp.SlUI.NavigationRegion.NavigationRegionView}) Line 230 + 0x1b bytes C# MyApp.SlUI!Kite.MyApp.SlUI.Components.ViewController.linksRegion_LanguageChanged(object sender = {Kite.MyApp.SlUI.Controls.LinksUserControl}, Kite.MyApp.SlUI.Common.EventArgs<string> e = {Kite.MyApp.SlUI.Common.EventArgs<string>}) Line 77 + 0x2d bytes C# MyApp.SlUI!Kite.MyApp.SlUI.Controls.LinksUserControl.OnLanguageChanged(string newLanguage = "en-GB") Line 37 + 0x32 bytes C# MyApp.SlUI!Kite.MyApp.SlUI.Controls.LinksUserControl.ComboBox_SelectionChanged(object sender = {System.Windows.Controls.ComboBox}, System.Windows.Controls.SelectionChangedEventArgs e = {System.Windows.Controls.SelectionChangedEventArgs}) Line 31 + 0xb bytes C# [External Code] What did I wrong?

  • wpf usercontrol within usercontrol with the help of region manager

    - by Miral
    Sorry for weird title, actually i can only explain my question but cannot put in a few words in the title. I am developing WPF Composite application with PRISM approach. I have got a common WPF usercontrol which is gonna be used by all other usercontrol, i.e. usecontrol within a usercontrol. The common usercontrol has got a button "ProcessMultiple" which I want it to behave differently from all usercontrol. I am using RegionManager to add this views. I have got PresentationModel for all the usercontrol IRegion historyUpdaterRegion = _regionManager.Regions["HistoryUpdaterRegion"]; IRegionManager historyUpdaterRegionManager = historyUpdaterRegion.Add(_unityContainer.Resolve<IHistoryDocumentUpdaterPresentationModel>().View, null, true); historyUpdaterRegionManager.RegisterViewWithRegion("ProcessMultiple", () => _unityContainer.Resolve<IProcessMultiplePresentationModel>().View); IRegion refundArrivalRegion = _regionManager.Regions["RefundArrivalRegion"]; IRegionManager refundArrivalRegionManager = refundArrivalRegion.Add(_unityContainer.Resolve<IRefundArrivalProcessorPresentationModel>().View, null, true); refundArrivalRegionManager.RegisterViewWithRegion("ProcessMultiple", () => _unityContainer.Resolve<IProcessMultiplePresentationModel>().View);

  • WPF with MVVM and Prismv2 - Event Bubbling?

    - by depictureboy
    What is the best way to get an event from a child or grandchild module up to the parent Shell? For instance, if I have a view in a module that is actually 2 levels away from the Shell, and I have a Window behavior. Is the eventaggregator really the best way to do this? it seems like overkill. I just want my MainShell to watch for a change in the IsDialogOpen Property on the ViewModels in all my child modules. I feel like I am missing the trees for the forest...

  • WPF DataGrid - Can't Use Mouse To Scroll Because Of Drag Drop

    - by OrPaz
    Hello, I am using a datagrid that is allowing to drag its rows. My problem is that when i try to scroll down on my grid using the mouse on the side scroller, i get the 'no enterance' sign that means that "drag and drop is not allowed here, dude...". How can i modify my drag and drop function to recognize that this is not a drag and drop action, but a scroll mouse action? private new void MouseMove(object sender, MouseEventArgs e) { if (e.LeftButton == MouseButtonState.Pressed) { Point currentPosition = e.GetPosition(GridUC); Object selectedItem = GridUC.SelectedItem; if (selectedItem == null) return; DragDropContainerObject ddObject = new DragDropContainerObject(typeof(Actor), selectedItem); DataGridRow container = (DataGridRow)GridUC.ItemContainerGenerator.ContainerFromItem(selectedItem); if (container != null) { DragDropEffects finalDropEffect = DragDrop.DoDragDrop(container, ddObject, DragDropEffects.Link); } } }

  • Composite events in locally scoped regions with Prism (CAL)

    - by Shaddix
    I'm starting to train Prism (CAL) with a small application and faced some problems. I'm creating multiple instances of my MainView, which itself contains some regions, and display them in the Shell. I'm using locally scoped regions to easily handle view injections within my MainView. Currently I'm searching for a way of communication between the views (viewModels) inside the MainView. Composite events could do it, but when I publish those events, they are handled in all instances of my MainView, which I really don't want. Is there a way of raising "locally scoped" composite events like with locally scoped regions? Or may be there's a better way of communicating between views in my case?

  • How do I load a module catalog from a database in Prism?

    - by Robert S.
    I'm using Prism in my WPF application and up to now, I've been loading the modules via var moduleCatalog = new ConfigurationModuleCatalog();. I'd like to get the module catalog from a database. The Prism documentation indicates that this is possible, but it doesn't go into any details. Has anyone done this and can provide some guidance?

  • WPF Composite - Expose EF model to all modules

    - by Tony
    Hi All, I have an application that uses WPF Composite, and I have an issue. I've got a big database that is attached to the application and I need it exposed to different modules as part of the application. What is the best way to expose my Entity Framework model to all my different modules and views inside them? Do I have one EF model or a separate one for each module and then only the tables that each module needs. The only problem being that some tables have a relationship and will have different views and those views will be in different modules. Any ideas how to resolve this?

  • StockTrader RI > Controllers, Presenters, WTF?

    - by SandRock
    I am currently learning how to make advanced usage of WPF via the Prism (Composite WPF) project. I watch many videos and examples and the demo application StockTraderRI makes me ask this question: What is the exact role of each of the following part? SomethingService: Ok, this is something to manage data SomethingView: Ok, this is what's displayed SomethingPresentationModel: Ok, this contains data and commands for the view to bind to (equivalent to a ViewModel). SomethingPresenter: I don't really understand it's usage SomethingController: Don't understand too I saw that a Presenter and a Controller are not necessary but I would like to understand why they are here. Can someone tell me their role and when to use them?

  • Differences between WPF Custom Control Library and plain Class Library?

    - by David Veeneman
    I posted a question a few months ago about sharing resource dictionaries across assemblies. It turns out you can do that using the Component Resource Key markup extension. At the time, I could only get it working with a WPF Custom Control project, not with a plain Class Library project. Now I need to use an existing plain Class Library project to host a shared resource dictionary. That means I need to retrofit the Class Library project to support the Component Resource Key markup extension. I have added a Themes folder and a Generic.xaml resource dictionary document to the Class Library project, as well as references to PresentationCore, PresentationFramework, and WindowsBase. Unfortunately, that doesn't seem to do the trick. So, here is my question: Other than the above, what does a WPF Custom Control Library project have that a plain Class Library project doesn't? Or, to put it another way, what else could I add to my class library project to get this feature working? Thanks.

    Anyone look at extending/integrating EventBroker in the EventAggregator in CAB/CAG ? Essentially looking at binding events based on string topics for binding publishers/subscribers in addition to the known event types defined in a common library !

  • WPF XAML Namespace import

    - by Andrey Khataev
    I've found that in order to use PRISM's classes in XAML you need to import namespace in that way: xmlns:cal="http://www.codeplex.com/CompositeWPF" this way is new to me, so I wanted to know, how hyperlink could be alias of usual notation of namespace import? so the intellisence knows in which assembly it should search this component? Thanks!

  • Ria Services vs WCF Dataservices

    - by NPehrsson
    My Team are evaluation to a bigger Business portal. (Invoicing, Bookkeeping, Salaries.....) We are all used to work with DDD, O/R mappers with NHibernate as our first choice. We have chosen to work with CompositeWPF to keep modularity between all modules and part system in the business portal. Now we have evaluated Ria Services and are kind of disappointed how it works in a Data Oriented way, Data Oriented can be good in a service oriented scenario, but we feel that we can with an Object Oriented approach to, and we feel that we can get an application with less complexity with the OO approach than the DO approach. For example it doesn't allow Value Objects, Many-to-many relations, everything needs to have keys and so on. We haven't looked at WCF Data Services yet so our question is WCF Data Services our answere? Does it integrate good with Silverlight 4? Can we work with it in a OO manor?
