  <pre><code>      System.Data.DataTable dt = null;
  
              string excelFile = Server.MapPath("./performances.xls");
              DataSet ds = new DataSet();
              // Connection String. 
              String connString = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + excelFile + ";Extended Properties=Excel 8.0;";
              // Create connection. 
              oledbConn = new OleDbConnection(connString);
              // Opens connection with the database. 
              oledbConn.Open();
              // Get the data table containing the schema guid, and also sheet names. 
              dt = oledbConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
              if (dt == null)
              {
                  return;
              }
              String[] excelSheets = new String[dt.Rows.Count];
              int i = 0;
              // Add the sheet name to the string array. 
              // And respective data will be put into dataset table 
              foreach (DataRow row in dt.Rows)
              {
                  excelSheets[i] = row["TABLE_NAME"].ToString();
                  OleDbCommand cmd = new OleDbCommand("SELECT * FROM [" + excelSheets[i] + "]", oledbConn);
                  OleDbDataAdapter oleda = new OleDbDataAdapter();
                  oleda.SelectCommand = cmd;
                  oleda.Fill(ds, "TABLE");
                  i++;
              }
              // Bind the data to the GridView 
              grdMygrd .DataSource = ds.Tables[0].DefaultView;
              grdMygrd.DataBind();
              Session["Table"] = ds.Tables[0];
