Hello Everyone,
I hit a wall while trying to output a crystal report in PDF format. After the report is loaded, I want to use the refresh method of the ReportDocument object so that the report can show the most update data then export it in PDF. But what I had been experiencing is that whenever I used the Refresh method the code always throws an exception in the line where the report needs to be exported in PDF format. When I don't use the Refresh method, the code doesn't break in the line where it has to export the document in PDF. I would like to know what alternative there could be. Because the code does what it was intended, which is connect to a database, run a stored procedure and then output the Crystal in PDF. It is just that the data shown is not up to date.
Any help would be truly appreciated.
Here the code:
ArrayList ParameterArrayList = new ArrayList(); //Report parameter list. Needs to be declared even if no parameters is being passed to the report
CrystalReportBase objReportBase = new CrystalReportBase(); //this is custom class that loads a crystal report, connect to a datasource, pass parameters to a report, and return a a return ReportDocument object
ReportDocument objReportDocument = new ReportDocument(); //Report document
try
{
string filterExtension = "*.rpt";
string substringInFileName = "M1_2_PhoneAnswerPerformance";
/*The report with two parameters. */
ParameterArrayList.Add(0);
ParameterArrayList.Add("No"); //Parameter 1 with input 1.
//ParameterArrayList.Add(1);
//ParameterArrayList.Add("1"); //Parameter 2 with input 1.
//retrieve connection information from the web2 connection string
objReportBase.ServerName = serverConnectionInfo.DataSource;
objReportBase.UserID = serverConnectionInfo.UserID;
objReportBase.Password = serverConnectionInfo.Password;
List<ReportFile> reportFiles = Utilities.GetFilesFromDirectory(@crystalPhoneReportPerformancePath, filterExtension, substringInFileName).ToList();
foreach (ReportFile reportFile in reportFiles)
{
objReportDocument = objReportBase.GenerateReport(reportFile.FileName, ParameterArrayList, crystalPhoneReportPerformancePath);
objReportDocument.Refresh(); Using this line causes....
//Save output report
objReportDocument.ExportToDisk(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat, string.Format("{0}{1}{2}", @crystalPhoneReportOutputMemberServicesPath, Path.GetFileNameWithoutExtension(reportFile.FileName), ".pdf")); ...the code to break in this line
//Export this file in Excel format as well
if (reportFile.FileName.Contains("CLHS_M1_2_PhoneAnswerPerformanceGraphs_Combined"))
{
objReportDocument.ExportToDisk(CrystalDecisions.Shared.ExportFormatType.ExcelWorkbook, string.Format("{0}{1}{2}", @crystalPhoneReportOutputMemberServicesPath, Path.GetFileNameWithoutExtension(reportFile.FileName), ".xls"));
}
}
//release those resources
objReportDocument.Dispose();
objReportDocument.Close();
objReportDocument = null;
catch{
