A Grid View Update Event Args object is passed to the event-handling method, which enables you to determine the index of the current row and to indicate that the update operation should be canceled.

To cancel the update operation, set the collections, if necessary, before the values are passed to the data source.

If the values for the control come from user input, be sure to validate the values to reduce security vulnerabilities.

In this section, you will add a button that enables client data changes to be saved back to the database.
