I export my data to pdf using the following c# code in asp.net:

private void Export(object sender, System.EventArgs e)
{

string strConnection = ConfigurationSettings.AppSettings["ConnectName"];

SqlDataAdapter da;
SqlParameter workParam;
da = new SqlDataAdapter("stpASTfandFByLoc", strConnection);
da.SelectCommand.CommandType = CommandType.StoredProcedure;

workParam = new SqlParameter("@pANALF1", System.Data.SqlDbType.Char);
workParam.Direction = ParameterDirection.Input;
workParam.Value =DropDownList1.SelectedItem.Value.ToString();
da.SelectCommand.Parameters.Add(workParam);



rptFandFByLoc crReportDocument = new rptFandFByLoc();
crReportDocument.SetDataSource(this.dstFandFByLoc1);

ParameterValues myparameterValues = new ParameterValues();
ParameterDiscreteValue myparamDiscreteValue = new ParameterDiscreteValue();
myparamDiscreteValue.Value = TextBox1.Text;
myparameterValues.Add(myparamDiscreteValue);


string ExportPath;
ExportPath = Request.PhysicalApplicationPath;
crDiskFileDestinationOptions = new DiskFileDestinationOptions();
crExportOptions = crReportDocument.ExportOptions;
Session["filename"] = Session.SessionID.ToString() + ".pdf";

crDiskFileDestinationOptions.DiskFileName = ExportPath + Session["filename"].ToString();

crExportOptions.DestinationOptions = crDiskFileDestinationOptions;
crExportOptions.ExportDestinationType = ExportDestinationType.DiskFile;
crExportOptions.ExportFormatType = ExportFormatType.PortableDocFormat;

crReportDocument.Export();

}
