The DetailsViewUpdatedEventArgs type exposes the following members.

Public methodDetailsViewUpdatedEventArgsInitializes a new instance of the DetailsViewUpdatedEventArgs class.

Public propertyAffectedRowsGets the number of rows affected by the update operation.
Public propertyExceptionGets the exception (if any) that was raised during the update operation.
Public propertyExceptionHandledGets or sets a value indicating whether an exception that was raised during the update operation was handled in the event handler.
Public propertyKeepInEditModeGets or sets a value indicating whether the DetailsView control should remain in edit mode after an update operation.
Public propertyKeysGets a dictionary that contains the key field name/value pairs for the updated record.
Public propertyNewValuesGets a dictionary that contains the new field name/value pairs for the updated record.
Public propertyOldValuesGets a dictionary that contains the original field name/value pairs for the updated record.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

The DetailsView control raises the ItemUpdated event when an Update button (a button with its CommandName property set to "Update") within the control is clicked, but after the DetailsView control updates the record. This allows you to provide an event handler that performs a custom routine, such as checking the results of an update operation, whenever this event occurs.

A DetailsViewUpdatedEventArgs object is passed to the event handler, which allows you to determine the number of records affected and any exceptions that might have occurred. To determine the number of records affected by the update operation, use the AffectedRows property. Use the Exception property to determine whether any exceptions occurred. You can also indicate whether the exception was handled in the event handler by setting the ExceptionHandled property. If you need to access the key field values for the updated record, use the Keys property. The original and updated non-key field values can be accessed using the OldValues and NewValues properties, respectively.

By default, the DetailsView control returns to the mode specified by the DefaultMode property after an update operation. To keep the DetailsView control in edit mode, set the KeepInEditMode property to true.

The following code example demonstrates how to use the DetailsViewUpdatedEventArgs object passed to the event handler for the ItemUpdated event to determine whether an exception occurred during an update operation.
