I transferred an Access 2010 table into a SQL Express DB and connected to it via Lightswitch. However, I cannot toggle Is Required, Allow Empty String, or Maximum Length validation properties for any column. Each one is disabled. How do I enable these properties?

The
Requiredcheckbox is controlled on the server-side with theAllow Nullsproperty. If the column allows null values, Lightswitch will say it’s not required, and vice-versa.
