Is this a web app or a winforms? Basically your problem is you are making a new datatable everytime. putting a single row in it and binding it to the gridview. You need to store that datatable somewhere and get rid of the
DataTable dtb = new DataTable();
line. How you store or hold that datatable depends on if this is a web app or winforms.
