Returns a full path from the current Item to the ChoiceActionBase.Items collection's first-level parent Item.
A string containing a chain of item captions from the current Item to the root parent Item, separated by the dot character.
Each ChoiceActionItem can have a collection of ChoiceActionItems, each of which can also have a collection of ChoiceActionItems, and so on. The entire Items collection of a ChoiceAction can contain two or more ChoiceActionItems with the same captions. You can uniquely identify an item via the GetItemPath method. For instance, if "Item121" is the current Item's caption, the GetItemPath method return value can be "Item1.Item12.Item121".
To access a ChoiceActionItem using its full path, use the SingleChoiceAction.FindItemByCaptionPath method.
