I am populating a ListBox by binding it to an ArrayList. The initial display is OK, but later changes to my ArrayList are not shown in my ListBox. How can I get the changes to show properly

In an ArrayList, the ’plumbing’ is not available to support two-way binding as with a dataset. So, you have to handle the synchronization yourself. One way to do this is to set the listBox1.DataSource to null and then reset it to your ArrayList. Another way is to use the CurrencyManager as shown in the code below.
