Direct PDF generation, without showing the report view

[Nebojsa Zecevic]

Hi,

I have implemented ejReportViewer into my app using RDLC on the server side, and data for RDLC is prepared on client side. And everything is working fine, report is generated and data is bind.

Now I came to requirement where i have to save PDF from ejReportViewer to DB, or some other server. Is it possible to use server side to directly generate PDF without client side ejReportViewer control?

What I have in mind is that on server side i have function where i send JSON data that should represent data source for RDLC, then function will parse report and export PDF. So on client side i get PDF (not report). So i can save this PDF somewhere else.

I saw that there is an ReportHelper, and ReportHelper.ProcessReport that are responsible for report parsing. Is there an option to export PDF with this class?

Kind Regards,

Nebojsa Zecevic

Hi Nebojsa,

Thanks for contacting Syncfusion Support.

We have option to export reports using our ReportWriter without rendering report in EJ ReportViewer control as shown in the below example,

HTML,

<form action="/api/ReportApi/ExportAction" method="post">

<input type="hidden" name="exporttype" value="PDF"/>

<input type="submit" value="Export"/>
</form>

WebAPI

public HttpResponseMessage ExportAction()

{

HttpResponseMessage _response = new HttpResponseMessage();

string writerFormat = HttpContext.Current.Request.Form["exporttype"];

string fileName = null;

WriterFormat format;

HttpContext httpContext = System.Web.HttpContext.Current;

ReportWriter reportWriter = new ReportWriter(httpContext.Server.MapPath("~/ReportTemplate/drilldown.rdlc"));

reportWriter.ReportProcessingMode = Syncfusion.EJ.ReportWriter.ProcessingMode.Local;

ReportDataSourceCollection dataSources = new ReportDataSourceCollection();

dataSources.Add(new ReportDataSource { Name = "Customers", Value = Customers.GetData() });

reportWriter.DataSources = dataSources;

fileName = "drilldown.pdf";

format = WriterFormat.PDF;

reportWriter.Save(fileName, format, httpContext.Response);

_response.StatusCode = System.Net.HttpStatusCode.OK;

return _response;

}

}

We have prepared a sample based on your request and it can be downloaded from the below location,

Hello,

i would like to know if I can do the same but passing some datasources from the client side, as in the "Control Creation" example from javascript where you pass the Datasource as a Json array.

Can I add an input and get it in the server side?

Thank you.

Hi Jaume, 

i would like to know if I can do the same but passing some datasources from the client side, as in the "Control Creation" example from javascript where you pass the Datasource as a Json array.

We have an API to pass the JSON data at client side in our ReportViewer control as shown in the below code example.    JS:       <script type="text/javascript">              $(function () {                  $("#container").ejReportViewer(                      {                          reportServiceUrl: "/api/ReportApi",                                                 processingMode: ej.ReportViewer.ProcessingMode.Local,                                                 reportPath: "~/Report/Sample.rdlc",                          dataSources: [{                              value: [                                  {                                      AddressID: 1,                                      City: "Tokyo",                                      StateProvinceID: 101                                  },                                   {                                       AddressID: 2,                                       City: "NewYork",                                       StateProvinceID: 102                                   },                                    {                                        AddressID: 3,                                        City: "Mumbai",                                        StateProvinceID: 103                                    },                                     {                                         AddressID: 4,                                         City: "Paris",                                         StateProvinceID: 104                                     },                                      {                                          AddressID: 5,                                          City: "Munich",                                          StateProvinceID: 105                                      },                              ],                              name: "DataSet2"                          }]                      });              });      </script>  We have prepared the sample using DataSource value from client side and it can be downloaded from the below location,    Sample: http://www.syncfusion.com/downloads/support/directtrac/general/ze/Reportsample-1139699116.zip     Pleases refer to the below UG documentation for more detail,  http://help.syncfusion.com/js/reportviewer/report-datasources     You can obtain the JavaScript ReportViewer samples from the below build installed location,  %userprofile%\AppData\Local\Syncfusion\EssentialStudio\version\JavaScript\reportsamples    Note: ReportWriter is a server side component and we could not initialize the ReportWriter control on client side.

Can I add an input and get it in the server side?

We can also pass the DataSource in server side (WebAPI) as shown in the below code example,      WebAPI:  public void OnReportLoaded(ReportViewerOptions reportOption)          {              reportOption.ReportModel.DataSources.Clear();              reportOption.ReportModel.DataSources.Add(new ReportDataSource { Name = "DataSet2", Value = Dataset.GetData() });          }          We have prepared a sample using DataSource value from server side and it can be downloaded from the below location,    Sample: http://www.syncfusion.com/downloads/support/directtrac/general/ze/ReportDemo-925832500.zip
