See more: C# ListBox Data-Binding
Have been trying to find a bit of code that will update a listbox in a windows form application with no luck.

When form loads this code populates the list, which works just fine:
private void Form1_Load(object sender, EventArgs e)
      {
          lbItemsList.DataSource = shoppingBasket.OrderItems;
      }

The listbox "lbItemsList" is binded to a class list called "shoppingBasket". When I add new items to the list then try to run the same line again, nothing happens. How can I update the listbox?

I've already tried the .Refresh() and .Update() methods and none of them work.

try this code

lbItemsList.DataSource = null;
lbItemsList.DataSource = shoppingBasket.OrderItems;
lbItemsList.EndUpdate();
