copied!<p>Ideally you do not want to use view logic in your viewmodel. Your viewmodel should not know anything about the view. It would be a better idea for your viewmodel to set a property letting the view know it's time to navigate. Here's an example:</p> <p><strong>ViewModel</strong>:</p> <pre><code>using System.ComponentModel; namespace ViewModels { public class MyViewModel : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; private void NotifyPropertyChanged(string propertyName) { if (PropertyChanged == null) return; PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } private bool _DoneDoingStuff; public bool DoneDoingStuff { get { return _DoneDoingStuff; } set { if (_DoneDoingStuff != value) { _DoneDoingStuff = value; NotifyPropertyChanged("DoneDoingStuff"); } } } } } </code></pre> <p><strong>View</strong>:</p> <pre><code><navigation:Page x:Class="Views.MyView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity" xmlns:ei="http://schemas.microsoft.com/expression/2010/interactions" xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation" xmlns:vm="clr-namespace:ViewModels"> <navigation:Page.Resources> <vm:MyViewModel x:Key="MyViewModelInstance" /> </navigation:Page.Resources> <Grid x:Name="LayoutRoot" DataContext="{Binding Source={StaticResource MyViewModelInstance}}"> <i:Interaction.Triggers> <ei:DataTrigger Binding="{Binding DoneDoingStuff}" Value="True"> <ei:HyperlinkAction NavigateUri="AnotherPage.xaml" /> </ei:DataTrigger> </i:Interaction.Triggers> </Grid> </navigation:Page> </code></pre> <ul> <li><p>Use a <code>DataTrigger</code> with <code>Binding</code> property set to the <code>DoneDoingStuff</code> property from your viewmodel, and the <code>Value</code> property set to "True". The <code>DataTrigger</code> will trigger when <code>DoneDoingStuff</code> from your viewmodel is set to true.</p></li> <li><p>Now you need a trigger action to navigate. Use <code>HyperlinkAction</code> with the <code>NavigateUri</code> property set to the page you're navigating to.</p></li> <li><p>Be sure to have <strong>System.Windows.Interactivity</strong>, <strong>System.Windows.Controls.Navigation</strong>, and <strong>Microsoft.Expression.Interactions</strong> assemblies in your references.</p></li> </ul> <p>At first, this might seem to be too much, but your view logic is now where it needs to be.</p>
