Hi Sreenivas,

First of all, I think it's better to post such questions to a list where all 
people interested in Mono can help you not only me. I cc'ed this to the Mono 
main List (mono-list@ximian.com). Give them a chance to help you next time,

Checking our status-page for Windows Forms at 
http://www.go-mono.org/class-status-System.Windows.Forms.html , I saw that 
DataGrid is at most  62% implemented. Also the whole System.Windows.Forms 
implementation is unstable just now so I would recommend not to use it  
before it matures.

GTK# isn't needed to run System.Windows.Forms apps, but many other packages 
are (like Cairo). But again Mono's implementation of System.Windows.Forms 
isn't completed yet.

For the general question the answer is: IF (BIG if, indeed) the third party 
controls are 100% Managed Code, and don't use System.Windows.Forms in an 
undocumented/non-portable way they possibly can run with Mono in Linux, but 
check if the license permits it (to run them outside of Windows & .NET).

Specifically for VSFlexGrid Pro you are out-of-luck as it is just an ActiveX 
control not a .NET Control. Mono won't support old-technology controls like 
that, because it costs too much in development (think we would have to 
duplicate lots of terrible COM/ActiveX support/interop code) and adds lots 
of potential bugs well-known in the COM world, as memory-leaks caused by 
circular references or unpaired calls into the reference-counting mechanism. 
You may have a better chance with Janus GridEX for .NET or Xceed Grid for 

Good developments,
