[Solved] Saving report to disk

I'm trying to follow the info on this page: https://docs.telerik.com/reporting/programmatic-exporting-report. However it doesn't show what the TypeName should be. I've tried many variations from other examples but I always get this error when the RenderReport line tries to execute:

Exception Details: System.ArgumentNullException: Value cannot be null.
Parameter name: type

var PDFSource = new TypeReportSource();

PDFSource.TypeName = "rptVAC";

var ReportProcessor = new ReportProcessor();

PDFSource.Parameters.Add(new Telerik.Reporting.Parameter("VACId", vacId));

var result = ReportProcessor.RenderReport("PDF", PDFSource, null);

[Solved] Report Designer VS 2017 doesn't show JSON datasource

Hi everyone,

I have updated the telerik reporting version from R1 2019(13.0.19.123) to R2 2019 (13.1.19.618) version. I use Visual Studio 2017 but can't see into Report Designer for VS2017 the JSON datasource or CSV Datasource. I mean are these features only appear in Standalone Report Designer or they has been included into Visual Studio Report Desginer?

See image #1 and #2 attached in order to see what is the popup I see in VS Report Designer when I try to connect with a Service.

Thanks,

David G.

Report 'Report1.trdp' cannot be resolved.

My View

<style>

#reportViewer1 {

position: relative;

width: 1300px;

height: 900px;

}

</style>

@(Html.TelerikReporting().ReportViewer()

.Id("reportViewer1")

.ServiceUrl(Url.Content("/api/reports/"))

.TemplateUrl("/Resources/Templates/telerikReportViewerTemplate.html")

.ReportSource(new UriReportSource() { Uri = "Report1.trdp" })

.ViewMode(ViewMode.Interactive)

.ScaleMode(ScaleMode.Specific)

.Scale(1.0)

.PersistSession(false)

.PrintMode(PrintMode.AutoSelect)

)

My controller

namespace OvalWeb.Controllers

{

using System.IO;

using System.Web;

using Telerik.Reporting.Cache.File;

using Telerik.Reporting.Services;

using Telerik.Reporting.Services.Engine;

using Telerik.Reporting.Services.WebApi;

//The class name determines the service URL.

//ReportsController class name defines /api/report/ service URL.

public class ReportsController : ReportsControllerBase

{

static ReportServiceConfiguration preservedConfiguration;

static IReportServiceConfiguration PreservedConfiguration

{

get

{

if (null == preservedConfiguration)

{

preservedConfiguration = new ReportServiceConfiguration

{

HostAppId = "OvalWebReport",

Storage = new FileStorage("C:/Storage"),

ReportResolver = CreateResolver(),

// ReportSharingTimeout = 0,

// ClientSessionTimeout = 15,

};

}

return preservedConfiguration;

}

public ReportsController()

{

this.ReportServiceConfiguration = PreservedConfiguration;

}

static IReportResolver CreateResolver()

{

var appPath = HttpContext.Current.Server.MapPath("~/");

var reportsPath = Path.Combine(appPath, @"Report\Designs\Ventas\Tickets\Familia");

return new ReportFileResolver(reportsPath)

.AddFallbackResolver(new ReportTypeResolver());

}

It shows me the error attached.

What could be the problem?

Dynamically change connection string using parameter

I want to create 1 report where a user would select a parameter and the report would connect to that parameters database.

Right now, I've created multiple reports that are pretty much the same except they are connecting to different databases. I would just like 1 report and based on the parameter the user chooses it will connect to that database.

Visual Studio Report Designer 2017, $metadata error

Hi,

I have tried to use the Visual Studio Report Designer for Telerik Reporting, my solution contains an asp.net core 2.1 web app and i have created an api controller, the idea is provide json data from my controller/actionresult in my web app to Report Designer Visual Studio 2017 to create a report though webservice datasource. I have recieved an error (see image#3_ReporDesignerVS2017.PNG attached). So, my question is: do the webservice datasource from designer allows connect with .SVC (WCF) or .ASMX (SOAP) services only? My web app retrieve data as REST service, what are your recommendations?

Thanks,

David Gonzalez,
