Overview	Refer to Working with Key Elements.

Remarks

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

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