Property Value

The number of rows affected by the delete operation.

Use the AffectedRows property to determine the number of records affected by the delete operation. This property is commonly used to verify that the correct number of records was deleted in the following situations:

  • Verify that only a single record was deleted. Sometimes an improperly written delete statement can delete multiple records.

  • Verify that a record was deleted when an error occurs during the delete operation that does not raise an exception.

  • Verify that a record was deleted when a data source control that supports optimistic concurrency (such as the SqlDataSource and ObjectDataSource controls) has its ConflictDetection property set to the ConflictOptions.CompareAllValues enumeration value. Under this setting, a record that has been modified by another user concurrently might not be deleted.

The following example demonstrates how to use the AffectedRows property to verify that a record was deleted during the delete operation.
