Gets or sets the name of a class that the ObjectDataSource control uses for a parameter in a data operation. The ObjectDataSource control uses the specified class instead of the Parameter objects that are in the various parameters collections.
Instead of specifying several parameters that are passed to the Select, Update, Insert, and Delete methods, you can create one object that aggregates several items. This one object is passed to the methods, instead of several parameters. For more information see ObjectDataSource.DataObjectTypeName.
