MoveLastElement method

Builder Syntax	int __fastcall MoveLastElement(bool bTree);
Delphi Syntax	function MoveLastElement(bTree: Boolean): Integer;
Overview	Refer to Working with Data Sets.

Remarks

Updates the CurrentElement property with the last item in the Data Set. The result depends on whether the Data Set is evaluated as a tree or a list.

If the Data Set is evaluated as a tree structure, this method updates the CurrentElement property with the last item on the same level and with the same parent as the item specified in the CurrentElement property. Please note that the numbering of the items in this illustration is arbitrary and does not imply order.
