Get selected items from listview object sender xamarin

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?

 

 

//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 }
