67 Views

Hi to all,

I have Asp.net 2.0-C# and Crystal report 11 SP2.

I wrote the cutom code for export to excel, it's working fine with 14 records, if it exceed more than 14 then it's hanged in this bolded code

strmRptDocument= new MemoryStream();

strmRptDocument = (MemoryStream)boReportDocument.ExportToStream(CrystalDecisions.Shared.ExportFormatType.Excel);

vwPage.Response.Clear();

vwPage.Response.Buffer = true;

vwPage.Response.ContentType = "application/vnd.ms-excel";

vwPage.Response.AddHeader("content-disposition", "attachment; filename=" + strExcelFileName);

vwPage.Response.BinaryWrite(strmRptDocument.ToArray());

HttpContext.Current.ApplicationInstance.CompleteRequest();

May i know what is the problem and how solve this.
