Hi All, I am a beginner to MVVM. The main window uses a stock DataGrid from the WPF Toolkit. It has one View Model and relies only on DataContext_Changed event handler in the .xaml.cs file. The main window's DataContext is the View Model. I am attempting to bind the ItemsSource property of a DataGridComboBoxColumn to a CLR property, "...
Is there a way to set focus from one control to another using WPF triggers? Like the following example <Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Grid> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> <RowDefini...
I am getting my knickers in a twist recently about View Models (VM). Just like this guy I have come to the conclusion that the collections I need to expose on my VM typically contain a different type to the collections exposed on my business objects. Hence there must be a bi-directional mapping or transformation between these two types...

What I have is a Shell with 2 ContentControls, "MenuRegion" and "ContentRegion". The way I want it to work is that a user will click on an item in the "MenuRegion" and then the approriate view will be displa...

Hello, Someone in Silverlight posted that MVVM currently lacks standardization so that everyone has own favor.. That's why Me and a few guys from WPF Disciples are actively discussing about MVVM that everyone agreed. I totally understand that we have implemented the pattern in different ways and we mixed the several patterns or creat...
I have a requirement in which a menu should be implemented as a treeview on the left side of a window. I know how to populate the treeview with the (menu)data (the mvvm way). But: how do i hook up each object in the treeview to an ICommand (in the Viewmodel)?? so that e.g. double clicking an object results in opening a window?? Thank...
Hey guys Just wondering if there are any good projects out there that use View Models. I am trying to get my implementation nailed down for how we are going to use VM's and there seems to be a few cross roads that I am coming up to and am wanting to see how other people handle these. Big bonus if the project uses ASP.net MVC 2.0. Che...
Hey guys I'm just wondering where people are creating their SelectList - in the action or the view. I have seen examples of both and the one that makes the most sense to me is doing it in the action and have the view model have a property of type SelectList. On the other hand, I have seen examples where people have the view model h...

I've got decent experience with C# however when it comes to an enterprise level app with all this new stuff, I'm a bit lost. My...
Hi! If one is implementing a WPF application using the MVVM design pattern, is there any situation in which to use value converters? It seems to me that value converters do exactly the same what the view model does too, that is preparing data for the view. So, are there some good uses for value converters? Best Regards Oliver Hanappi ...

I've been using MVVM pattern for a while now, but I still run into problems in real-life situations. Here's another one: I use commanding and bubble up the event to be handled in the ViewModel. So far, so good. But the project for which I'm using MVVM is actually a class library. Once I run the command code, I need to be able to send...
