Dynamics CRM has an extension for developers that lets them interact with Dynamics CRM forms using a HUD (Heads-Up Display). The HUD displays information about all of the controls and even allows developers to change the visibility of those controls at run time.

Additionally, the HUD can show all of the information that is available for an entity in Dynamics CRM. It includes the entity name, the logical name, the record's Guid, the entity's attributes, and the entity's relationships.

The developer can use the Fetch With Return of Results query to get the entity records from the CRM database, and they can use it with the results displayed on the page.
