Starting in 2019, the Reporting control is no longer included in Essential Studio®. If you're experiencing issues with the Syncfusion� Reporting Platform, Report Viewer, Report Designer, or Report Writer, we recommend migrating to Bold Reports, our dedicated reporting platform.

Bold Reports offers a comprehensive suite of tools and features for all your reporting needs, and we will help you make a smooth transition from the discontinued control. Our support team at https://support.boldreports.com/ is here to assist you with any questions or difficulties you may encounter during the migration process.

We thank you for choosing Syncfusion� and appreciate your understanding.

Initial zoom factor and Report Parameters

Hi
For a report viewer page in my ASP.net MVC5 app, I want to set initial zoom levels to 200% and "Whole Page"
It does not seem to be working
I tried this

 @(Html.EJ().ReportViewer("reportsample").ProcessingMode(Syncfusion.JavaScript.ReportViewerEnums.ProcessingMode.Remote).ReportServiceUrl(VirtualPathUtility.ToAbsolute("~/api/reportviewer")).ReportPath("~/App_Data/STA_IrradianceVsGeneration.rdl").RenderingComplete("myRepLoaded").ZoomFactor("200%").IsResponsive(true).ToolbarSettings(tb => tb.Items(Syncfusion.JavaScript.ReportViewerEnums.ToolbarItems.All & ~Syncfusion.JavaScript.ReportViewerEnums.ToolbarItems.PageNavigation)))

but the report is rendered at 100% only

Secondly
I cannot extract some report parameters during ReportRenderingComplete Event handling
  var reportviewerObj = $("#reportsample").data("ejReportViewer");
        reportviewerObj.fitToPageWidth(); // To fit the report page width.
        reportviewerObj.fitToPageHeight();
        var data = (reportviewerObj.getParameters()); // To get the parameters.
        
       var obj = JSON.parse(JSON.stringify(data));

While obj[0].Name, obj[0].Prompt,obj[0].DataType  are readable, obj[0].Value and obj[0].Label are 'Undefined', while, I can see them in Json String returned to the browser.
Pls note that the parameter holder is a combobox (date selector in  yyyy-MM-dd format). The date list comes from a query/


Please advise
Regards
Ajay

Hi Enrochem, 
 
Thanks for contacting Syncfusion support.

(VirtualPathUtility.ToAbsolute("~/api/reportviewer")).ReportPath 
("~/App_Data/STA_IrradianceVsGeneration.rdl") 
.RenderingComplete("myRepLoaded").ZoomFactor("200%") 
.IsResponsive(true).ToolbarSettings(tb => tb.Items(Syncfusion.JavaScript.ReportViewerEnums.ToolbarItems.All & ~Syncfusion.JavaScript.ReportViewerEnums.ToolbarItems.PageNavigation))) 
but the report is rendered at 100% only 
 
We were able to reproduce the mentioned problem at our end and logged this as an bug report. We will consider to include this bug in our Essential studio volume 1 SP 1 2018 release.

We can get the default parameter value specified in the report when using the “renderingComplete” event in ReportViewer directly as shown in below code example,  
 
            function onreportcomplete(args) {               
                var reportviewerObj = $("#container").data("ejReportViewer"); 
                reportviewerObj.fitToPageWidth(); // To fit the report page width. 
                reportviewerObj.fitToPageHeight(); 
 
                if (args.reportParameters == 'undefined') { 
 
                    var data = args.reportParameters; // To get the parameters. 
                    var obj = JSON.parse(JSON.stringify(data)); 
                    var label = obj[0].Label; //label 
                    var value = obj[0].Value; //value 
                } 
            } 

We have prepared a sample and it can be downloaded from below location, 
 
Please refer to the below UG document for more detail,
