Accounts Dictionary

Create an application that lists accounts from a Dictionary object. Create an Account class that contains an ID, name, and balance. Display the accounts in a ListBox, as shown in Figure 8-42. If the user enters new values, she can click on the Add button to add a new account to the dictionary. If she clicks the Replace button, she can replace a dictionary item. Use exception handlers to catch errors caused by invalid input values, or an attempt to add a duplicate Account ID to the dictionary. Note: Remember to save the Dictionary in Session state to avoid losing your changes when the page is posted back to the server.
