This will create a Parameter object in the ObjectDataSource's SelectParameters collection that does not have a value specified. To set this value programmatically, we need to create an event handler for the ObjectDataSource's Selecting event.

To accomplish this, go to the Design view and double-click the ObjectDataSource. Alternatively, select the ObjectDataSource, go to the Properties window, and click the lightning bolt icon.

Next, either double-click in the textbox next to the Selecting event or type in the name of the event handler you want to use.
