mvvm-light

I 've recently started working with WPF using MVVM light and I have the following (simple scenario). MainWindow contains a listbox of elements. When one is selected and the button is clicked, I fire a command: ReservoirViewerCommand.Execute(null); On the viewmodel class I instantiate the command and send a message with the selected object: ReservoirViewerCommand = new RelayCommand(OpenReservoir); private void OpenReservoir() { Messenger.Default.Send(new LaunchShowReservoirMessage(){Reservoir=SelectedReservoir}); } where: class LaunchShowReservoirMessage:MessageBase { public Reservoir Reservoir

This helpful class seems to be gone from the latest MVVM Light build, any idea why or how to work around it? I'm using MvvmLightLibs.5.0.1.0, was definitely there on MvvmLightLibs.4.1.27.0. So this question is not related with one EventToCommand Missing For Windows Phone App Environment: VS2013, WP8.0 Eventually, I found the EventToCommand class on Galasoft.MvvmLight.Platform. I guess the assembly change makes sense being a multi-platform framework. xmlns:Command="clr-namespace:GalaSoft.MvvmLight.Command;assembly=GalaSoft.MvvmLight.Platform" <i:Interaction.Triggers> <i:EventTrigger EventName=

Is it possible to pass a whole row as a parameter for the Hyperlink of DataGridTemplateColumn? <my:DataGridTemplateColumn Header="Name"> <my:DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock> <Hyperlink Foreground="Black" TextDecorations="None"> <Run Text="{Binding Name}" /> </Hyperlink> </TextBlock> </DataTemplate> </my:DataGridTemplateColumn.CellTemplate> </my:DataGridTemplateColumn> Hard to tell what you are trying to achieve but a ComandParameter binding without a value should give you the row eg <Hyperlink Foreground="Black" TextDecorations="None" CommandParameter="{Binding}"

I have a Timer and three buttons to control it: Start, Stop, and Pause. Each button is bound to a RelayCommand. I have a TimerState property of type enum TimerState . (This is useful for setting various GUI elements.) Is there a way to somehow bind the RelayCommands' CanExecute functionality to the TimerState property? Currently, I have 3 methods that look like this: private bool CanStartTimer() { return (TimerState == TimerState.Stopped || TimerState == TimerState.Paused); } In the TimerState setter, I call StartTimerCmd.RaiseCanExecuteChanged(); Is there a better way bind the CanExecute

I am currently building a WP7 app using the MVVMLight framework. I would like to add a resource dictionary to my app.xaml, however when I do it fails. Here is a snipit from the app.xaml <Application.Resources> <!--Global View Model Locator--> <vm:ViewModelLocator x:Key="Locator" d:IsDataSource="True" /> <!--Merged Resource Dictionaries--> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="View/StyleResourceDictionary.xaml"/> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> Because I am using a ViewModelLocator that

XAML File <Grid> <Button x:Name="Button1" Content="Button 1" Command="{Binding Button1Command}"/> <Button x:Name="Button2" Content="Button 2"/> </Grid> ViewModel File public class MyViewModel : ViewModelBase { public ICommand Button1Command{get;private set;} public MyViewModel(){ Button1Command = new RelayCommand(() => button1_Click()); } private void button1_Click() { Console.WriteLine("Button 1 clicked"); // how can I change the background color of Button 2 here this.Dispatcher
