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.


Best wishes,

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

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.

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?

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,

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.

 
Regards,

Chavdar

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,
Svetoslav
