If you want to dynamically change the contents of items source, use ObservableCollection instead, so you will have access to Add() method.

private ObservableCollection myStrings;

public MyClass()
{
    myStrings = new ObservableCollection();
    myControl.ItemsSource = myStrings;
}

private void AddNewItem(string item)
{
    myStrings.Add(item);
}
