File List Sorting based on sorting parameter

Problem Definition:
For a given file list with properties like FileName, Location, DateCreation, DeteModification, Type - sort it based on supplied argument - in other words implement functionality of applying sort mechanism (windows) based on headers clicked.

Output:
