Цитата:

Form Items are available from the Xrm.Page.ui.formSelector.getCurrentItem or the Xrm.Page.ui.formSelector.items collection. A form item represents a form that is available to a user because it is associated with a security role that the user is also associated to. Often there will be only one form. When more than one form is available, these methods can be used to change the form the user is viewing.
