How the Update Customers sample works

The application consists of two classes. The CustomerUpdate user interface class manages the display of data and the selection or editing of customer data. The WebServiceManager class uses web service methods to retrieve data and to save the comment information. The WebServiceManager class also shows how to place the summary list data returned by a web method into a dataset. The user interface's drop-down list controls use the datasets as the source of the data they display.

The application uses basic error handling techniques to detect exceptions and displays all error information in message boxes.
