Remarks
The value of the DataItemLinkReference property must be specified as the Name of a parent data item.
The default value is the name of the last preceding data item in the report with lower indentation. You can set DataItemLinkReference and DataItemLink properties for a data item that is not a child of another data item, however, this will not have any effect.
