An ObjectListCommand object can be declared as a <command> element within the declaration of an ObjectList.

An ObjectListCommand object can be also constructed, and added programmatically to an ObjectList, by adding it to the control's Commands member collection.

The following example shows how to create an ObjectListCommand object. This example is part of a larger, more complete example for the ObjectList overview.
