You can get the ListView first  and then get the Selected ListViewItem  I have an example for ListBox  but ListView should be similar   private void listBox MouseDoubleClick object sender  MouseButtonEventArgs e                ListBox box   sender as ListBox          if  box    null                return                    MyInfo info   box SelectedItem as MyInfo          if  info    null              return             your code here                      e Handled   true

Was having a similar issue with a ListBox wanting to open a window  Different View  with the SelectedItem as the context  in my case  so I can edit it    The three options I ve found are  1  Code Behind 2  Using Attached Behaviors 3  Using Blend s i Interaction and EventToCommand using MVVM-Light   I went with the 3rd option  and it looks something along these lines    lt ListBox x Name  You Need This Name    ItemsSource   Binding Your Collection Name Here   SelectedItem   Binding Your Property Name Here  UpdateSourceTrigger PropertyChanged       rest of your needed stuff here      gt   lt i Interaction Triggers gt   lt i EventTrigger EventName  MouseDoubleClick  gt       lt Command EventToCommand Command   Binding Your Command Name Here            CommandParameter   Binding ElementName You Need This Name Path SelectedItem         gt       lt  i EventTrigger gt   lt  i Interaction Triggers gt    That s about it     when you double click on the item you want  your method on the ViewModel will be called with the SelectedItem as parameter  and you can do whatever you want there

I found this on Microsoft Dev Center  It works correctly and ignores double-clicking in wrong places  As you see  the point is that an item gets selected before double-click event is triggered   private void listView1 DoubleClick object sender  EventArgs e           user clicked an item of listview control     if  listView1 SelectedItems Count    1                  do what you need to do here                       http   social msdn microsoft com forums en-US winforms thread 588b1053-8a8f-44ab-8b44-2e42062fb663

It s annoying  but the best way to do it is something like    lt DataTemplate Name  MyCoolDataTemplate  gt       lt Grid Loaded  HookLVIClicked  Tag   Binding RelativeSource  RelativeSource FindAncestor  AncestorType  x Type ListViewItem     gt           lt  -- your code here -- gt       lt  Grid gt   lt  DataTemplate gt    Then in the code   public void HookLVIClicked object sender  RoutedEventArgs e        var fe    FrameworkElement sender      var lvi    ListViewItem fe Tag      lvi MouseDoubleClick    MyMouseDoubleClickHandler

I don t yet have a large enough reputation score to add a comment where it would be most helpful  but this is in relation to those asking about a  Net 4 5 solution   You can use the mouse X and Y co-ordinates and the ListView method GetItemAt to find the item which has been clicked on   private void ListView MouseDoubleClick object sender  MouseButtonEventArgs e        ListViewItem item   myListView GetItemAt e X  e Y         Do something here
