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