if you are creating buttons dynamicly , you can use the Tag property for attach your data, or inherit the Button class as My_Button and set a Property wich you need like "userId"

in the other way try watch the Parent property of clicked button.

for example :

private void Button_Click(object sender, RoutedEventArgs e)
        {
          Button clickedButton = sender as Button;
          ListViewItem holderItem = clickedButton.Parent as ListViewItem;
          Console.WriteLine("You are clicked the buton in " + holderItem.Name);
        }

or inline solution:

private void Button_Click(object sender, RoutedEventArgs e)
            {
              Console.WriteLine("You are clicked the buton in " + ((sender as Button).Parent as ListViewItem).Name);
            }

DataContext is your friend. Each list item (and button inside that item if you haven't override button's DataContext) will have a data item which was used to generate the item in DataContext property.
