Hi Ramco, The issue is due to the following code, the output is more than a single record. Can you please try the first / firstordefault

context.TicketAnalysis.Single(rec => rec.TicketID == Convert.ToInt32(hdfTicketId.Value));

Please let me know if still issue persists.
:)

Hi Jignesh

On below code i am getting same error

if (FileUpload1.HasFile)
                {
                    String fileName = FileUpload1.FileName.Substring(0, FileUpload1.FileName.LastIndexOf("."));

                    strname = fileName + "_" + name + FileUpload1.FileName.Substring(FileUpload1.FileName.LastIndexOf("."), 4);

                    strname = strname.Replace(':', '_').Replace('-', '_').Replace('\\', '_').Replace('/', '_').Replace(' ', '_').Replace('+', '_').Replace('&', '_').Replace('@', '_').Replace('#', '_');

                    FileUpload1.SaveAs(Server.MapPath(FolderPath) + strname);

                    String ext = System.IO.Path.GetExtension(FileUpload1.FileName);
                    TicketAnalysi objUpload = context.TicketAnalysis.Single(rec => rec.TicketID == Convert.ToInt32(hdfTicketId.Value));
                    {
                        objUpload.Attachment1 = strname;
                        context.TicketAnalysis.InsertOnSubmit(objUpload);
                        context.SubmitChanges();
                    };
                }

Thanks

Hello Ramco,

Inside foreach loop you need to change if() condition as below,
```
if(postedFile.HasFile)
{
......
......
......
}
```
