How to use INotifyChanged

Question

I have a listbox in my xaml.I am adding items to this listbox using List<Object> i.e,partList.

 

public void setList() 

{

   for (int i = 0; i < partList.Count; i++)

   {

      var partListItem = partList[i].getLine().getItem();

      PartListPhoneControl userPhoneControl= new PartListPhoneControl();

 

      if (partListItem.getDescription() != null)

          userPhoneControl.partDescription.Text = partListItem.getDescription();

    }

} 

 

Now if I am doing any changes in this list I want it to refresh the list box.How can I use INotifyChanged in this case?
