Handles to the Objects in a Form

When programming in a form you can reference the individual objects, for
example the data sources or controls of the form, using the kernel classes used to
build them, or by overriding the methods on the object itself.
All methods in the form are related to an object. The object can be accessed from
the methods associated with it, by using the handle this. Note that this reference
is relative to where you are programming.
When referencing an object from a method that is not associated with that object,
you need to use the object handle. The following table lists the objects and how
to access them:

Object	Access from X++
FormRun	Element
FormDataSource	<name of data source>_DS
Active record in data source	<name of data source>
FormDataObject	FormDataSource.Object(<fieldId>)
FormDesign	FormRun.design()
Form……Control	Name assigned to control, when property AutoDeclaration is set to Yes. or element.control(Control::<name of control>)

Query	<name of data source>_Q or FormDataSource.Query()
QueryRun	<name of data source>_QR or FormDataSource.QueryRun()

The method control() on the element object can be used if the control is included
in an auto field group. In this situation you cannot use the auto declaration
feature.
