Creating a PDF from a RDLC Report in the Background

Question

I am running a month-end process and want to have it automatically create some of the reports that need to be created at that time  I am using rdlc reports  Is there a way to automatically create a PDF from a RDLC report in the background

This is easy to do  you can render the report as a PDF  and save the resulting byte array as a PDF file on disk  To do this in the background  that s more a question of how your app is written  You can just spin up a new thread  or use a BackgroundWorker  if this is a WinForms app   etc  There  of course  may be multithreading issues to be aware of   Warning   warnings  string   streamids  string mimeType  string encoding  string filenameExtension   byte   bytes   reportViewer LocalReport Render       PDF   null  out mimeType  out encoding  out filenameExtension      out streamids  out warnings    using  FileStream fs   new FileStream  output pdf   FileMode Create         fs Write bytes  0  bytes Length

You don t need to have a reportViewer control anywhere - you can create the LocalReport on the fly   var lr   new LocalReport       ReportPath   Path Combine Path GetDirectoryName Assembly GetExecutingAssembly   Location       C      Reports    PathOfMyReport rdlc        EnableExternalImages   true     lr DataSources Add new ReportDataSource  NameOfMyDataSet   model     string mimeType  encoding  extension   Warning   warnings  string   streams  var renderedBytes   lr Render                PDF              lt DeviceInfo gt  lt OutputFormat gt PDF lt  OutputFormat gt  lt HumanReadablePDF gt False lt  HumanReadablePDF gt  lt  DeviceInfo gt            out mimeType          out encoding          out extension          out streams          out warnings         var saveAs   string Format   0  pdf   Path Combine tempPath   myfilename      var idx   0  while  File Exists saveAs         idx        saveAs   string Format   0   1  pdf   Path Combine tempPath   myfilename    idx      using  var stream   new FileStream saveAs  FileMode Create  FileAccess Write         stream Write renderedBytes  0  renderedBytes Length       stream Close       lr Dispose      You can also add parameters   lr SetParameter     handle subreports   lr SubreportProcessing  YourHandler   or pretty much anything you can think of

You can use following code which generate pdf file in background as like on button click and then would popup in brwoser with SaveAs and cancel option   Warning   warnings          string   streamIds          string mimeType   string Empty          string encoding   string Empty  enter code here          string extension   string Empty          DataSet dsGrpSum  dsActPlan  dsProfitDetails              dsProfitSum  dsSumHeader  dsDetailsHeader  dsBudCom   null       enter code here    This is optional if you have parameter then you can add parameters as much as you want ReportParameter   param   new ReportParameter 5               param 0    new ReportParameter  Report Parameter 0    1st Para   true               param 1    new ReportParameter  Report Parameter 1    2nd Para   true               param 2    new ReportParameter  Report Parameter 2    3rd Para   true               param 3    new ReportParameter  Report Parameter 3    4th Para   true               param 4    new ReportParameter  Report Parameter 4    5th Para                 DataSet  dsData   Fill this dataset with your data               ReportDataSource rdsAct   new ReportDataSource  RptActDataSet usp GroupAccntDetails   dsActPlan Tables 0                ReportViewer viewer   new ReportViewer                viewer LocalReport Refresh                viewer LocalReport ReportPath    Reports AcctPlan rdlc     This is your rdlc name              viewer LocalReport SetParameters param               viewer LocalReport DataSources Add rdsAct      Add  datasource here                      byte   bytes   viewer LocalReport Render  PDF   null  out mimeType  out encoding  out extension  out streamIds  out warnings                  byte   bytes   viewer LocalReport Render  Excel   null  out mimeType  out encoding  out extension  out streamIds  out warnings                  Now that you have all the bytes representing the PDF report  buffer it and send it to the client                           System Web HttpContext Current Response Cache SetCacheability HttpCacheability NoCache               Response Buffer   true              Response Clear                Response ContentType   mimeType              Response AddHeader  content-disposition    attachment  filename  filename          extension               Response OutputStream Write bytes  0  bytes Length      create the file               Response Flush       send it to the client to download               Response End

The below code work fine with me of sure thanks for the above comments  You can add report viewer and change the visible false and use the below code on submit button   protected void Button1 Click object sender  EventArgs e        Warning   warnings      string   streamIds      string mimeType   string Empty      string encoding   string Empty      string extension   string Empty      string HIJRA TODAY    01 10 1435       ReportParameter   param   new ReportParameter 3       param 0    new ReportParameter  CUSTOMER NUM   CUSTOMER NUMTBX Text       param 1    new ReportParameter  REF CD   REF CDTB Text       param 2    new ReportParameter  HIJRA TODAY   HIJRA TODAY        byte   bytes   ReportViewer1 LocalReport Render           PDF            null           out mimeType           out encoding           out extension           out streamIds           out warnings        Response Buffer   true      Response Clear        Response ContentType   mimeType      Response AddHeader           content-disposition             attachment  filename  filename          extension       Response OutputStream Write bytes  0  bytes Length      create the file       Response Flush       send it to the client to download       Response End
