The GridView is just a View on the datas which you DataSource holds. So if you change some value in the GridView the underlying DataSource automaticly changes the value. I recommend you to build a class which represents one data set. Then you create a List<MyClass>
and use this as DataSource. So your BusinessObjects change automaticly if someone edit a value in the Grid.
To your question:
If you want to show the data in a new Table just create a new Grid and populate the List<MyClass>
again. If you want to show the saved data only clone you List<MyClass>
on SaveButton Click and populate it.
I hope i understand you. If you need further help i post an short example.
