Thanks for your reply but the link you have given has some codes missing so I'm not able to implement.
The sample code has screen in it, whose object is it.
U can use subLayout() through which you can set the fields and also the Flow field manager.
If you have icon,label,Editfield then use HorizontalFieldManager.
Make a new instance of HorizontalFieldManager for every row.
It is working.
Try it out.
Thnks for the suggestion.
