I plan on writing a WPF app following the MVVM pattern for the first time but something is not quite clear to me. Let's say that the view has a "Save" button and when that is hit I need to save the current state of my data (the model). This will be done by sending a SOAP message to a SOAP service. Where in my MVVM setup do these SOAP ...
i took a look at some questions here at stack overflow like this & mix10 building your own mvvm framework i wonder if as a beginner its better to start from scratch (but i heard from the vid, its not recommended) or use a framework also which is more suited as a beginner framework to learn? i find that after reading quite a few article...

First, I apologize for my low level English writing. I use Entity Framework and data-binding in WPF MVVM project. I would like to know what is the best way to do data binding to added calculated property of EntityObject which is generated with Entity Framework.

I have a silverlight datagrid to which I am binding an observable collection from the viewmodel. There is a detail view page which will display different properties of the object in the collection when user selects a row of the datagrid. My requirement is when user updates any properties in the detail view; the data should be updated in ...
I'm currently trying to create a small application using the MVVM pattern. However I don't really know how to correctly wrap up aggregated Model classes in my ViewModel. From what little I know about MVVM, you're not supposed to expose Models in your ViewModel as properties or else you could directly bind to the Model from your View. So ...
I've worked with PRISM on one major project before so I'm pretty familiar with the concepts involved but I'm about to embark on a self managed project and was wondering if anyone has any pearls of wisdom about how to go about implementing an appropriate architecture for a straight forward LOB/Forms over data app. I'll want to leverage as...

Something that continues to confuse me about MVVM - if I use the view-first approach to constructing my objects (this appears to be the most common approach, at least after much reading and searching), how do I get contextual information into the viewmodel? I've seen many answers to similar questions say "use the DI container to inject ...
Hi! I have a typical MVVM scenario: I have an ItemsControl bound to an ObservableCollection of StepsViewModels. I define a DataTemplate so that StepViewModels are rendered as StepViews. The same happens in the StepView: I have an ItemsControl to an ObservableCollection of ParameterViewModels with a DataTemplate to render them as Paramete...
A few weeks ago, I came across this article in MSDN magazine which talks about MVVM in general. One of the things that stood out to me was the DynamicViewModel class. It addresses the code-duplication problem common to applications using the MVVM pattern. So I wonder, has anyone else tried using it? What do you think of it? See, as...
I have a Page within a WPF navigation-style application that displays search results. The page contains several data-bound controls. The page itself works fine; it performs the search and returns results. The data-bound CheckBox controls work properly. But if I click a result link and then click the back button to return to the results ...
Hello, I have an wpf mvvm application. I try to write checkbox list control. I can bind the checkbox list elements. Added to this issue, I want to get sum of the selected checkbox list elements values. I added DependencyProperty and bind it to view model property. But, they dont fire each other.

Hi. I am gathering data in a separate Task and I want to data bind the result to a GUI component using an ObservableCollection<>. So my code goes something like this: private ObservableCollection<MyItem> _items; public ObservableCollection<MyItem> Items { get { return _items; } set { if (_items.Equals(value)) { retur...
I have the Xaml which should basically bind a set of ContextualButtons for a selected tab's viewmodel to the ItemsSource property of the ToolBar. For some reason, this binding is not actually occuring unless I use Snoop to inspect the element manually...It seems that the act of snooping the element is somehow requerying the binding some...
Hi, suppose the following classes: public class Model { public ObservableCollection<A> Items { get; set; } } public class A { ObservableCollection<B> Data { get; set; } //... some more properties } public class B { //..properties } The model is bound to a RibbonMenu and should also be used in a context menu. The co...
I wanted to do a quick user control for my app, but to keep things in a MVVM style I thought I'd set the DataContext of the XAML to the code behind in my UserControl. i.e. DataContext="{Binding RelativeSource={RelativeSource Self}}" This allows me to bind the XAML to properties in my code behind. Everything went well until I came to...
