Hi,

i have been getting "Thread was being aborted" Exception when a report is being exporting to PDF.

i am using the following code to export report into a PDF.

protected void btnPrint_Calculation(object sender, EventArgs e)
{
GeneratePrint();
}
public void GeneratePrint()
{
try
{
Document doc = new Document(new RectangleReadOnly(842, 595), 88f, 88f, 10f, 10f);
System.IO.MemoryStream MyStream = new System.IO.MemoryStream();
BaseColor Black = new BaseColor(00, 00, 00);
iTextSharp.text.Font MyFont = FontFactory.GetFont("vardana", 12, iTextSharp.text.Font.BOLD, Black);
PdfWriter Writer = PdfWriter.GetInstance(doc, MyStream);
doc.Open();
string HeaderTitle = "AIR ROTOR TECHNOLOGIES PVT LTD,";
string SubHeaderTitle = " 303,Center Facility Building 2,Sector 19,Vashi,";
string SubHeaderTitle1 = "chikmaglur";
PdfPTable HeaderTable = new PdfPTable(1);
PdfPCell HeaderCell = new PdfPCell(new Phrase(HeaderTitle, new Font(Font.FontFamily.HELVETICA, 15f, Font.BOLD, BaseColor.RED)));
PdfPCell SubHeaderCell = new PdfPCell(new Phrase(SubHeaderTitle, new Font(Font.FontFamily.HELVETICA, 14f, Font.BOLD, BaseColor.BLACK)));
PdfPCell SubHeaderCell1 = new PdfPCell(new Phrase(SubHeaderTitle1, new Font(Font.FontFamily.HELVETICA, 10f, Font.NORMAL, BaseColor.BLACK)));
HeaderCell.Border = 0;
HeaderTable.AddCell(HeaderCell);
HeaderTable.AddCell(SubHeaderCell);
HeaderTable.AddCell(SubHeaderCell1);
PdfPCell text = new PdfPCell(HeaderTable);
Response.Clear();
// Response.AddHeader("content-disposition", "attachment;filename=SaleRegisterReport.pdf");
Response.ContentType = "application/pdf";
Response.BinaryWrite(MyStream.ToArray());
Response.End();
doc.Close();
}
catch (Exception Ex)
{
Response.Write("While printing Caught an Error" + Ex.Message);
}
}

In place of Response.End() write the following code and try
Response.BuffferOutput = True;
Response.Flush();
Response.Close();
