If I understand you right, you have found a work-around for you case.

If the discovery date is null I wish to denote that the planet was discovered before recorded human history.

Introduction Step 1: Replicating the Example from "Tutorial 17: Examining the Events Associated with Inserting, Updating, and Deleting" Step 2: Converting the Bound Fields into Template Fields Step 3: Adding the Validation Controls to the Grid View's Edit Item Templates Step 4: Summarizing Data-Entry Problems Step 5: Adding the Validation Controls to the Details View's Insert Item Template Step 6: Partitioning the Validation Controls into Validation Groups Conclusion The Grid View and Details View controls in the examples we've explored over the past three tutorials have all been composed of Bound Fields and Check Box Fields (the field types automatically added by Microsoft Visual Studio when binding a Grid View or Details View to a data source control through the smart tag).
