Conditional formatting in Excel


We are currently using the Infragistics4.WebUI.Documents.Excel.v17.1.dll version. What we would like to accomplish is to copy the conditional formating rules of the cells of a row to the cells of another row.

The initial template can have only a few rows predefined (due to download size limitations). But the export can contain up to thousand records.

Until now we managed to copy all formatting and styles of a cell, apart from the conditional formatting rules. 

All the posts I found on this topic are old, so I am wondering if this feature is implement in this version already? And how can we accomplish the desired task?

Thank you.
