mvvm-light

Trying to figure out how to use EventToCommand to set a datagrid double click handler for rows. The command lives in the viewmodel for each row. Just that much out of my experience, since I haven't used interactions yet. Thanks. I would have used mvvmlight tag, but I don't have high enough rep yet to make new tags. This would be the solution if the Command lives on the "GridVieModel" and not on the "RowViewModel". <Window... ...xmlns:dg="clr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit" xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity" xmlns

How i can implement state handling (running / resume / Terminate states ) using mvvm light. The major issue i a facing is with Navigation. I am totally uncontrolled with the navigation stack. How i can effectively manage this with MVVM Light. You might be interested in the open source Okra App Framework that is freely available on CodePlex and NuGet (disclaimer: I am the lead developer on this project). This has been designed from the ground up for Windows 8 applications, in particular those that use the MVVM pattern (and you can still use the MVVM Light base classes to define your view-models

In a WPF application, you can put your global static resources in app.xaml .. like <Application.Resources> <!--Global View Model Locator--> <vm:ViewModelLocator x:Key="Locator" d:IsDataSource="True" /> </Application.Resources> That was from MVVM Light ;). Now, if your project is a wpf class library, what is a proper way to initialize such global static resources? You can create a ResourceDictionary with your resources and merge the dictionaries using your code as below. <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:vm="clr-namespace:WPFProject

When I add the MVVM Light package via NuGet I get errors referencing the lines in the App.xaml file added during the install. These errors only appear in Windows Phone 8 projects. The exact same lines in a Windows Phone 7 project do not raise any errors. The MVVM Light added lines are: <ResourceDictionary> <vm:ViewModelLocator x:Key="Locator" d:IsDataSource="True" /> <ResourceDictionary.MergedDictionaries></ResourceDictionary.MergedDictionaries> </ResourceDictionary> These lines are positioned just before the ending </Application.Resources> tag. The errors reported in the Error List pane are:

Currently i'm developing an WPF application with the MVVM-light framework. On this moment i'm setting my settings as shown in the next example code in my viewmodel: private string _property public string Property { get { return _property; } set { if (_property != value) { _property = value; Settings.Default.Property = value; RaisePropertyChanged("Property"); } } } I save my settings on application exit: protected override void OnExit(ExitEventArgs e) { Settings.Default.Save(); } Everything works as intended, but ... Question: Is this a correct approach or is there a better way of handling

I find out that the EventToCommand for the Loaded-event is not working as expected if the Window.SizeToContent attribute is set to WidthAndHeight . The Loaded-event seems to be fired correctly, but the EventToCommand.Command property is bound AFTER the Loaded event is fired. If SizeToContent is Manual the Command will be bound BEFORE Loaded is fired and it works as expected. Does anyone also have problems with this behavior and/or an explanation for this? My workaround for now is to bind to the DataContext of the window: <i:Interaction.Triggers> <i:EventTrigger EventName="Loaded" > <command

I'm curently teaching myself the MVVM pattern. I've hit my first snag with the concept of messaging. I know messaging is contained in the mvvm-light toolkit. But I cannot find an example of usage anywhere (no sample projects are provided in the download). If anyone can direct me to some information as to how to use messaging in that toolkit, that would be ace. Thanks I found the following article on the subject. The subject line seems a little unrelated but that link is for part 2 of the article and if you read and scroll down a bit you will find info on the RelayCommand, Messenger,
