print my report straight to pdf

[rob mays]

Instead of having my web report open up in the report viewer. Can i have some C# code on how to export my report straight to open a PDF file on the clients browser? Please.

Hi Rob,

You can use the following code snippet to programmatically export the report into "PDF" format from a Web Site or Web Application project:

void ExportToPDF(string reportName, Telerik.Reporting.Report reportToExport)
    {
        string mimeType = string.Empty;
        string ext = string.Empty;
        Encoding encoding = Encoding.Default;

        byte[] reportBytes = Telerik.Reporting.Processing.ReportProcessor.Render(
            "PDF"
            , reportToExport
            , null
            , out mimeType
            , out ext
            , out encoding);


        string fileName = reportName + ".pdf";

        Response.Clear();
        Response.ContentType = mimeType;
        Response.Cache.SetCacheability(HttpCacheability.Private);
        Response.Expires = -1;
        Response.Buffer = false;

        Response.AddHeader("Content-Disposition",
                           string.Format("{0};FileName=\"{1}\"",
                                         "attachment",
                                         fileName));

        Response.OutputStream.Write(reportBytes, 0, reportBytes.Length);
        Response.End();
    }

For the Web Site you may need to manually specify the folder in which the "PDF" rendering extension is located using this code line: 

    Telerik.Reporting.Processing.ReportProcessor.ExtensionDir = HttpContext.Current.Server.MapPath("~/bin");

Also, make sure that Telerik.Reporting.ImageRendering.dll resides in the Bin folder of the application.

many thanks for the excellent reply. firtst class forum. just what i needed

[NightFlash]

where do I have to past that code, could be usefull for me aswell.

[rob mays]

can i have some more info please, dont fully understand what you waqnt to do.

[NightFlash]

I also want to export my report straight to a PDF file. Chavder gave you the code for that, but how do I have to use the code, where do I have to past it. And how do I have to link it? Because it's just a normal function, so you have to link it somewhere.

Thnx already,
Kevin

[rob mays]

what I did was in a new aspx page in the page load I create an instance of the report in the page load event, then in the page load event I call the ExportToPDF function passing it the name I give the report, then the actual report as the second parameter. If you are in the uk give me a number and i can help you more if needed.

[NightFlash]

ok, thanks mate! I'm going to try it over an hour! I live in Belgium so I think that would be a little bit too expensive :) I let you know something in 1,5hour!

[rob mays]

if you get stuck let me know and i will past you my c# code on how i did it

[NightFlash]

Ok! I think I find out how it works. But it's not like I want :( Because I work like this:

I have a page where you can select some options, this I forward in a querystring to another page where I request this querystring. On that page I request data from my database with those variables. And after that I bind it to the report. And with the script bellow you can't send variables :(

Any ideas mate?

[rob mays]

what is the name name of your report? first try to get it to display in the telerik reportviewer? r u able to do that?
here is my code in the page load event. there are no controls on this page what so ever.

ReportLib.Plumbworld.rptDeliveryNotices.PassDeliveryDate = Session["DeliveryDate"].ToString();

ReportLib.Plumbworld.rptDeliveryNotices rpt = new ReportLib.Plumbworld.rptDeliveryNotices();

ExportToPDF("Deliveries", rpt);

[NightFlash]

Nice writen script! But what is this (red, underline)

ReportLib.Plumbworld.rptDeliveryNotices.PassDeliveryDate = Session["DeliveryDate"].ToString();

I work like this, the code I show is on the page load of my reportviewer: 

//here I request my data
VerhuurGeschDA verhuurGeschDA = new VerhuurGeschDA();

VerhuurGeschData data = verhuurGeschDA.GetDataNietBetaald("Kevin", Request.Querystring["var1"].ToString());

//here I attach my data to my reportviewer
ReportViewer1.Report = (Telerik.Reporting.Report)new VerhuurRapport();

ReportViewer1.Report.DataSource = data;

Hello,

I try the code given by Chavdar on 14tyh June... and I get this message :

"sys.webforms.pagerequestmanagerparsererrorexception the message received from the server could not be parsed ... ...  ... "

I think it is due to the fact that the linkbutton event where I call the method is not making a regular PostBack because this linkbutton is linked to a RadAjaxManager Prometheus....

Do you have any idea to help me ?

Thank for your help,

[rob mays]

//here I request my data
VerhuurGeschDA verhuurGeschDA = new VerhuurGeschDA();

VerhuurGeschData data = verhuurGeschDA.GetDataNietBetaald("Kevin", Request.Querystring["var1"].ToString());

//here I attach my data to my reportviewer
VerhuurRapport myReport = new VerhuurRapport();

//the export to pdf dont need report viewer
ExportPDF("YourReport",myReport)

Hi Emmanuel,

You are right that the ajaxification of the LinkButton is causing the trouble. The browser's build-in XmlHttpRequest object doesn't interpret correctly the content type of the response and there is nothing we can do to fix this behavior. Given this you have the following choices: 

• To remove the LinkButton from the ajaxified controls list and allow it do regular postbacks
• To use Respose.Redirect in the Click event handler and redirect to a page that can serve the report:
    
  protected void LinkButton1_Click1(object sender, EventArgs e)
  {            
      Response.Redirect("ExportReport.aspx");
  }
   
  and in the Page_Load event of the ExportReport.aspx have something like this:
   
  protected void Page_Load(object sender, EventArgs e)
  {
      this.ExportToPDF("Report1", new Report1());
  }
   
• Use javascript code to manually make a new request to the report page.

For your convenience I have attached several sample pages which show the approached mentioned above. Let me know if you have any other questions.

Hi

i need to generate PDF in landscape format. any suggestion on this requirement will be a great help.

Thanks in advance

[Svetoslav]

Hi thulasiram,

All you need to do is to set the Report.PageSettings to the desired page orientation like this:

myReport.PageSettings.Landscape = True

where myReport is Telerik.Reporting.Report class instance.

All the best,
