Hi
Using ListView Behaviors, How do I get values/object of selected item or selected row?

Below is what i tried and I get a property that says "SelectedItem" but i cant access it. What am I missing?

What I have tried:

<ListView.Behaviors>
               <behaviors:EventHandlerBehavior EventName="ItemSelected">
                   <behaviors:InvokeCommandAction Command="{Binding OnItemSelected}"  />
               </behaviors:EventHandlerBehavior>
           </ListView.Behaviors>

//constructor
 public BurialsViewModel()
        {
     _onItemSelected = new Command(OnSelectedItem);
         }

//viewmodel

ICommand _onItemSelected;
      public ICommand OnItemSelected
      {
          get { return _onItemSelected; }
      }
      void OnSelectedItem(object sender)
        {
           //I need values from sender
        }

Hard to tell from the limited code snippets. It appears that you have not bound the ItemsSource of the ListView control to the collection in your ViewModel. Also, there should be a SelectedItem property that you can bind to without doing it the way that you are. [update:] Here is how to databind: ListView Data Sources - Xamarin[^]

Xamarin[^] has a tonne of resources[^] that you can learn from. Here is a link that offers more than what you need but will cover what you want: Multi-select ListView - Xamarin[^]. Also check out their forums...[^]
