    copied!<p>I find J King answer quite good, but I will like to shed some more light and options never the less.</p> <p>In the comment you asked about what happens if it's not the same view?<br> Here's an implementation I have: </p> <pre><code>&lt;ListBox x:Name="YourListView" ItemsSource="{Binding SomeCollection}" SelectedItem="{Binding SelectedItemObject, UpdateSourceTrigger=PropertyChanged}" ToolTip="Double click to edit" &gt; &lt;ListBox.ContextMenu&gt; &lt;ContextMenu&gt; &lt;MenuItem Header ="Edit me" Command="{Binding Edit_Command}" CommandParameter="{Binding SelectedItemObject}" /&gt; &lt;MenuItem Header ="Delete me" Command="{Binding Delete_Command}" CommandParameter="{Binding SelectedItemObject}" /&gt; &lt;/ContextMenu&gt; &lt;/ListBox.ContextMenu&gt; &lt;i:Interaction.Triggers&gt; &lt;i:EventTrigger EventName="MouseDoubleClick"&gt; &lt;Command:EventToCommand Command="{Binding Edit_Command}" CommandParameter="{Binding ElementName=YourListView, Path=SelectedItem}" /&gt; &lt;/i:EventTrigger&gt; &lt;/i:Interaction.Triggers&gt; &lt;/ListBox&gt; </code></pre> <p>Notice that either double clicking on an object in that list, or right clicking and selecting one of the two options (namely <code>edit</code> and <code>delete</code>), will Call a command with a paramater.</p> <p>Now, when you use the <code>ContextMenu</code> since you right clicked and object, it's selected, and you can just send it.</p> <p>In the case of the double click, I'm using the name of the listbox to get the item.</p> <p>From here what I'll do in the viewmodel is something like:</p> <pre><code>private void Execute_Edit(object param) { var your_object = (cast_to_your_type)param; Messenger.Default.Send(new SwitchView(new SomeViewModel(_dataService,your_object))); } </code></pre> <p>The ICommand will call <code>Execute_Edit</code>, which in turn will send a message using the Messenger.</p> <p>This is how I defined <code>SwitchView</code>:</p> <pre><code>/// &lt;summary&gt; /// Used as message, to switch the view to a different one. /// &lt;/summary&gt; public class SwitchView { public SwitchView(MyViewModelBase viewmodel) { ViewModel = viewmodel; } public MyViewModelBase ViewModel { get; set; } } </code></pre> <p>My MainWindow is registered to listen to those messages,and we know what to change to (obviously, to the view model given : <code>SomeViewModel</code>). The <code>SwitchView</code> on the main class will change the ViewModel property to the property the message passed.</p> <p>Here's what I have in my main view:</p> <pre><code>&lt;Border &gt; &lt;ContentControl Content="{Binding Current_VM}" /&gt; &lt;/Border&gt; </code></pre> <p>So, whatever the <code>Current_VM</code> property is set to, will show you that view.</p> <p>Hope that helped :)</p>
