Property Value

The number of rows affected by the update operation.

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

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

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

  • Verify that a record was updated when a data source control that supports conflict detection (optimistic concurrency checking), 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 updated.

The following example demonstrates how to use the AffectedRows property to verify that a record was updated.

No code example is currently available or this language may not be supported.
