DetailsViewUpdateEventArgs Class

Note: This class is new in the .NET Framework version 2.0.

Provides data for the ItemUpdating event.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public ref class DetailsViewUpdateEventArgs : public CancelEventArgs
public class DetailsViewUpdateEventArgs extends CancelEventArgs
public class DetailsViewUpdateEventArgs extends CancelEventArgs

The DetailsView control raises the ItemUpdating event when an Update button (a button with its CommandName property set to "Update") within the control is clicked, but before the DetailsView control updates the record. This allows you to provide an event handler that performs a custom routine, such as HTML-encoding the values of a record before updating it in the data source, whenever this event occurs.

A DetailsViewUpdateEventArgs object is passed to the event handler, which allows you to determine the value of an optional command argument sent to the DetailsView control and to indicate whether the update operation should be canceled. To determine the value of the command argument, use the CommandArgument property. To cancel the update operation, set the Cancel property to true. You can also read or modify the new values entered by the user by using the Keys and NewValues properties. The Keys property contains the key fields, while the NewValues property contains the non-key fields. If you need to access the original non-key field values, use the OldValues property.

For more information about handling events, see Consuming Events.

For a list of initial property values for an instance of the DetailsViewUpdateEventArgs class, see the DetailsViewUpdateEventArgs constructor.

The following code example demonstrates how to use the DetailsViewUpdateEventArgs object passed to the event handler for the ItemUpdating event to validate the values entered by the user.
