Description

Refreshes the parameter values of the detail dataset and re-executes it.

SQL datasets establish master/detail relationships by supplying parameter values from the master dataset. ActiveChanged updates these parameter values on the detail dataset to reflect the current values of the master dataset and then refreshes the dataset so that it is populated with the new detail set.
