Question

i have a array of objects, for example people and info about them. how could i determine who was selected in the listbox where only their first and last name is shown? Is it even possible somehow to link a item in the listbox with a item in the array? Obviously i can’t rely on SelectedIndex because when the names in the listbox get filtered it just doesn’t work anymore.

In my application i have a listbox where are the names of persons and when i click on one person in the listbox i want to see their detais (address/contacs/misc). And the problem is when two persons share the same name.

You could use the ListBox.SelectedItem like this… If you wanted you could create a new property to concatenate the FirstName and Surname and use it as your DisplayMember

public class Person
{
    public string FirstName { get; set; }
    public string Surname { get; set; }
}

var people = new[]
{
    new Person{FirstName = "Peter", Surname = "Pan"}, 
    new Person{FirstName = "Simon", Surname = "Cowell"}
};

var listbox = new ListBox
{
  DisplayMember = "FirstName",
  ValueMember = "FirstName",

  DataSource = people
};

var person = listbox.SelectedItem as Person;
