Microsoft Dynamics 365 Blog

In this blog you will find attached a very simple usage of .NET interoperability with Dynamics NAV 2009 R2 with the objective of basic file management (move, copy, open, delete) WITHOUT using the FILE virtual table and is intended just to familiarize with this brand new feature proposed with NAV 2009 R2 release.

File management is made at client side (RoleTailored client side).

If you want to know more about .NET interoperability for NAV 2009 R2, please refer to MSDN link:

Extending Microsoft Dynamics NAV Using Microsoft .NET Framework Interoperability

.NET interoperability (variables) are generally based on the System.IO namespace:





My ingredients:

  • Microsoft Dynamics NAV 2009 R2
  • Windows 7 Enterprise

What you will find in the TXT file:

  • 2 Tables
    • T.50100 Client Files Management Buffer
    • T.50300 Client Files Management Setup
  • 1 Page
    • P.50200 Client Files Management


What to do to let it work (initial setup):

1. Populate the Client Files Management Setup table 50300 with the appropriate values :

  • User ID -> windows login (without domain)
  • Default From Path -> Initial path where to take the file from (NOTE: do not add the backslash at the end, the application will do this for you)
  • Default To Path -> Path where to copy/move files to (NOTE: do not add the backslash at the end, the application will do this for you)


2. Once you have completed setup as per point 1, now you are really ready to manage files using the RTC and simply run Page 50200 Client Files Management.

Action buttons Legend:

 Move Back – Move Forward

These are enabled since the beginning and permit the user to browse up and down the Directories hierarchy.


Once you have selected your source file (From File), these buttons will be shown. They permit the user to Open (a simple HYPERLINK) or delete the file selected. If the To file is selected (the “Done” option in the To File is selected) these actions refer to the To File. (Obviously you can change this how you wish, since you have the code under your fingers).


COPY File – MOVE File

These are the clue actions. They are enabled once the user has selected both the source file (From File) and the destination file (To File) and checked the 2 “Done” Options for “Manage File” and “Into File” groups (as reported in the first screenshot).
