hi.....,

          DataView myDataView = new DataView();
          myDataView = ds1.Tables[0].DefaultView;
          if (sortExp != string.Empty)
          {
              myDataView.Sort = string.Format("{0}{1}",sortExp,sortDir);

          }

.....................
          grd.DataSource = myDataView;

          DataTable dt3 = new DataTable();
          dt3 = myDataView.Table.Copy();
          ds.Tables.Add(dt3);

you may take bakup after sorting .......

like this

ds.WriteXml("c://Backup.xml"); /// where ds is DataSet ds=new
DataSet();

when you need again load it in DataSet.....
like this........

string myXMLfile = "C:\\BackUp.xml";
DataSet ds = new DataSet();
try
{
ds.ReadXml(myXMLfile);
dataGrid1.DataSource = ds;
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
