try
{
      sqlConnection1.Open();
      sqlDataAdapter1.Fill(dsCustomers1);
}
catch (Exception ex)
{
      if(Request.IsLocal)
      { Session["CurrentError"] = ex.Message; }
      else
      { Session["CurrentError"] = "Error processing page."; }
      Server.Transfer("ApplicationError.aspx");
}
finally 
{
      this.sqlConnection1.Close();
}
