The following example demonstrates how to use the RowUpdating event to update the values in the data source object when the data source is set programmatically.
The RowUpdating event is raised when a row's Update button is clicked, but before the GridView control updates the row. This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.
A GridViewUpdateEventArgs 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. You can also manipulate the Keys , OldValues , and NewValues collections, if necessary, before the values are passed to the data source.
A common way to use these collections is to HTML-encode the values supplied by the user before they are stored in the data source. This helps to prevent script injection attacks. The grid highlights the modified cells in green and deleted rows in gray. This grid also displays the "Recover" button for deleted rows. To hide the deleted rows, set the SettingsEditing.
HighlightDeletedRows property to false. If a grid contains modified data, it displays a confirmation message before a grid performs a postback or a callback. The KeepChangesOnCallbacks property specifies whether the grid supports callbacks and allows you to use the 'Preview changes' button to preview and modify inserted, deleted and edited rows before you click 'Update'.
