Update your Button's click handler

<Button Click="Button_Click"  />

Access Button's tag in code

private void Button_Click(object sender, RoutedEventArgs e)
{
   var tag = (sender as Button).Tag;

   //do tag dependent work
}

Side Note: Button_click is called for any button clicked inside your data-binding but sender will be the specific instance of the clicked button that's why you can access all of its properties.
