Well, how do you know the XML was changed ? Where is it ? If it's changed, then you can rebind to it. If it's a file on the hard drive, you can use a file watcher to get a report when the file is changed, and reload it.

can't we use .update() or .refresh() method to update rows ??

No. You have to reload the XML file entirely. XML is not a database, so it doesn't support retrieving just the "changed" rows.

Yes. Dave you are right we need to relod the xml file,
Do one thing open that xml file in notepad and make changes whatever you want and save it as same file name(Dont forget to put the extension .xml once again) in same drive after that system will aking for replacing the file click yes after run your application, it will work.

cheers..
