Answer 1

try in this way

MainLongListSelector.ItemsSource = c.details.Where(elem=> elem.Property==5).ToList();// returns elements with Property=5

I am assuming that your details has a property with name Property but you can use your fields eg .Where(elem=> elem.Name=='Peeter' && elem.Age > 30) //takes elements with Age > 30 and Name=Peter
