hi There is another method called merge. eg: DataSet ds2 = new DataSet(); ds2.Merge(ds1.Tables[0].Rowstrue);//ds1 is filled //and retrieved from database. // Second parameter is preserve changes. But with this function dataset's orignial structure may get overriden use true for second parameter and make sure table structure of rows passed matches that of original.
