The Visual Studio Team Explorer work item datasheet view is quite limited in functionality. The TFS Work Item Explorer tool allows developers to define their own custom drilldown tree of WIQL queries in an XML file (“template”), leveraging global values (e.g. server name, project name, etc.), field values (of parent queries of any generation) and user choices (a.k.a. parameters). Each TFS project can be associated with its own template via the application configuration file stored under the user's profile. Out of the “box”, TFS Work Item Explorer includes a Scrum for Team System template, which mimics the behavior of the now deprecated Scrum Explorer tool.
