  Crystal Report Export and Print button not working inside UpdatePanel

  Nov 16, 2006 11:33 AM|LINK

  Hi

  Iuse UpdatePanel for my pages, clients requested to view pages without flickering.

  So, I put all component in update panel, but after that, export and printing for Crystal Reports stoped to work. If I put report viewer outside of updatepanel its working.

  Have anyone this problem? There's some solution for this?

  Thanks, Paul

  i donno much abt update panel.. but hope this information might be helpful for u..

  Viewstate should be enabled for the page where u r placing viewer..(Enableviewstate= true in page directive).. if its not enabled then print and download options will not work properly..

  How about using an IFrame?
  I had the same problem & solved it using an IFrame.
  It might not be the best solution, but it works.

  Hi,

   I had the same problem. I ended up disabling CrystalReportViewer's toolbars and I created my own button that displayed the report as PDF in new window. And if I remember correctly, the button would have to be outside the update panel and use some JavaScript.

  exactly....

  i also did this as klin6on said. when a button clicks a new window will pop up and displays the report in pdf format. if u want like this i'll give you the code....

  dim rpt as new reportdocument  

   rpt.ExportToDisk(ExportFormatType.PortableDocFormat, Server.MapPath("~/Export/Personnel.pdf"))
  Dim popupscript As String = "<script language='javascript'>" + "window.open('Export/Personnel.pdf');</script>"
  Page.ClientScript.RegisterStartupScript(Me.GetType(), "PopUpWindow", popupscript, False)

  Hi,
  
  I applied the idea of joseabie.
  It was a good idea, but there were some issues:
  Using the same file path for all reports might conflict with different reports.
  Even using different file names will be a problem because then the export directory will keep growing.
  How would you like to know with which files are not being used so you can remove them?
  Another issue is that the page reloads unnecessarily.

  This is how I solved the problem(C#):

  I created a page which contains my report which returns report files in an HttpResponse at the page load with the following code:

  PrintPDF.aspx.cs:

  ReportDocument rpt = CrystalReportSource1.ReportDocument;
  rpt.SetParameterValue("@paramater1", Request.Params["parameter1"]);
  rpt.SetParameterValue("@parameter2", Request.Params["parameter2"]);
  rpt.ExportToHttpResponse(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat, Response, true, "ReportName");

  Then instead of linking the popup script to the click method I used the following code in the load event of the button so I can keep it in the updatepanel:

  CrystalReport.aspx.cs:

  Button printButton = (Button)sender;
  string path = PrintPDF.aspx?parameter1=value1&parameter2=value2");
  string script = String.Format("window.open('{0}')", path);
  printButton.Attributes.Add("onclick", script);

  Please let me know if it is not clear.

  I think this is the easiest way (for me at least)

  You need two pages, myPage.aspx and OpenFile.aspx

   
  Code extract myPage.aspx

   

  private ReportDocument rd;
  
          private void CreateCrystalReport()
          {
              rd.SetParameterValue("MyField", "MyValue");
                          
              /*export to pdf*/
              ExportOptions expo = rd.ExportOptions;
              expo.ExportDestinationType = ExportDestinationType.DiskFile;
              expo.ExportFormatType = ExportFormatType.PortableDocFormat;
              expo.DestinationOptions = new DiskFileDestinationOptions();
  
              string fileName = "report";
              string filePath = @"~/tmpStorage/" + fileName;
              
              rd.ExportToDisk(ExportFormatType.PortableDocFormat, Server.MapPath(filePath + ".pdf"));
  
              Session["reportDocument"] = rd;
  
              string script = "<script language='javascript'> window.open('OpenFile.aspx?action=401&filepath=" + filePath + "&filename=" + fileName + "');</script>";
  
              ScriptManager.RegisterStartupScript(this, typeof(myPage), "PopupCP", script, false);
              
          }

   
   Code extract OpenFile.aspx

   

      public partial class OpenFile : System.Web.UI.Page
      {
          private ReportDocument rd;
          protected void Page_Load(object sender, EventArgs e)
          {
              this.Unload += new EventHandler(OpenFile_Unload);
  
              string action = string.Empty;
              if (Request["action"] != null)
                  action = Request["action"];
  
              if (action == "401")
                  CreatePdfResponseFor401();
          }
  
          void OpenFile_Unload(object sender, EventArgs e)
          {
              //remember to clean up
              if (rd != null)
              {
                  rd.Close();
                  rd.Dispose();
                  Session["reportDocument"] = null;
                  GC.Collect();
              }
          }
  
          private void CreatePdfResponseFor401()
          {
              string filePath = Request["filepath"];
              string fileName = Request["filename"];
  
              if (filePath == null)
                  throw new ArgumentNullException("error message");
  
              if (fileName == null)
                  throw new ArgumentNullException("error message");
  
              rd = Session["reportDocument"] as ReportDocument;
  
              if(rd == null)
              {
                  throw new ArgumentNullException("error message");
              }
  
              rd.ExportToHttpResponse(ExportFormatType.PortableDocFormat, Response, true, fileName);
          }
      }
