I created dataGridViewer connected to a database , when I change the records and reopen the application the changed are saved However , I let the user to add/delete columns during the runtime (by using sql command) ,even though those columns are saved and appear at datagridviewer 

The reported Viewer (which i designed using wizard) is not showing these columns
