Hi Team,

We are getting the error message "Internal Server error. The Device is not ready"

Is there a solution/fix available to avoid the following error which occurs inconsistently."
"Internal Server error. The device is not ready! .

Kindly let us know when this issue will occur since we are not able to reproduce consistently

PFA error snapshot for the exact error details

Additional Details : Issue occurs only when we host the application in IIS, when we run locally we dont have any issues.

 

I have 5 groups in my report (say Group 1, Group 2, Group 3, Group 4, Group 5)
Group 1 - parent, Group 2 - child of Group 1, Group 3 - child of Group 2, Group 4 - child of Group 3 and Group 5 - child of Group 4

Group 4 and Group 5 are by default true but Group 1, 2 & 3 depends on the parameter (with multivalue/checkboxes - Group 1, 2 ,3)
i.e. user can choose combination of Group 1,2,3 or null

How can I set it up in the Telerik Report Designer?

Something like this--

Group1 - depends on parameter value
Group2 - depends on parameter value
Group3 - depends on parameter value
Group4 - always true
Group5 - always true
Data:- Name, Amount
Data:-Total by Group4  Sum(Amount)

It should always show the Data no matter what combination of parameters user choose or null.

Hello,

I am trying to use HTML5 Report Viewer with MVC extension helper.

I have an error "Unable to get report parameters: Missing report name". It is happening during POST request to /api/reports/clients/210953-ab00/parameters which gets 400 Bad Request. 

I guess because request data do not have report: parameterValues: {} report: null

I call HTML helper like that:

    @(Html.TelerikReporting().ReportViewer()
        .Id("reportViewer1").ReportResolver(new TypeReportSourceResolver())
        .ServiceUrl("/api/reports/")
        .TemplateUrl(Url.Content("~/ReportViewer/templates/telerikReportViewerTemplate.html"))
        .ReportSource(new InstanceReportSource(){ReportDocument = new SessionReport()})
        .ViewMode(ViewModes.INTERACTIVE)
        .ScaleMode(ScaleModes.SPECIFIC)
        .Scale(1.0)
        .PersistSession(false)
    )

I have my ReportController implemented like:

public class ReportsController : ReportsControllerBase
    {
        protected override IReportResolver CreateReportResolver()
        {
            var reportsPath = HttpContext.Current.Server.MapPath("~/Reports");

            return new ReportFileResolver(reportsPath)
                .AddFallbackResolver(new ReportTypeResolver());
        }

        protected override ICache CreateCache()
        {
            return Telerik.Reporting.Services.Engine.CacheFactory.CreateFileCache();
        }
    }

And as I am using MVC5 with WepApi2 I have in my web.config following (I am not sure about last entry for Newtonsoft.Json):

      <dependentAssembly>
        <assemblyIdentity name="System.Web.Http" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0-5.1.0.0" newVersion="5.1.0.0" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.Net.Http.Formatting" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0-5.1.0.0" newVersion="5.1.0.0" />
      </dependentAssembly>
      <dependentAssembly>

        <bindingRedirect oldVersion="1.0.0.0-4.5.0.0" newVersion="4.5.0.0" />
      </dependentAssembly>

Can you help, please? Regards, Yegor.

hello,

I'm using Telerik Reporting HTML Viewer (telerikReportViewer-8.1.14.618.min.js). 
In the server side I'm using Telerik.Reporting in c#.
All are work perfectly but once every few months all reports are stop working, 
I get some http errors in some telerik reporting automatic requests.


Sometimes I got the error for the following request:
POST http://web.otech.co.il/otech/api/reports/clients  
the response is:

This error is occurred on known report that worked perfectly before.



I'm try restart the IIS, restart the computer ant etc. , nothing helped.
When I copy the entire site directory  and configure new site in IIS - It started work again.
Also, If I copy the entire site directory to another new directory and just configure the existing site to link to the new directory - also it started work..

Do you know what can be the reason of this problem? It's very worth for my customer to stop and recreate the site once every few months..

Thanks,

Chani

I followed the steps in the Telerik reporting video found here: https://www.youtube.com/watch?v=UF1mL6vzJDs. I was able to get everything working on my development machine but when I put it up on the webserver, it just gets to the part where the page says "loading..." and stops.  No error, nothing.  Any suggestions on what I might be missing.  I am able to tell that it at least gets to this line in the index.html:  <script type="text/javascript">
        $(document).ready(function () {

Thanks,

 

Jennifer

Hello,

I'm trying to setup reports in my Angular application.  I've followed the guides and I'm stuck at creating the REST service. My setup:

 

Angular 6 application

.NET Core Web API

Telerik REST Project

 

When following this guide:

https://docs.telerik.com/reporting/telerik-reporting-rest-host-http-service-using-web-hosting

 

I get an error when using the project template.  It's

"The name 'AreaRegistration' does not exist in the current context"

 

Any ideas would be appreciated.

I am receiving the following error (used Fiddler to find it) when attempting to load ReportViewer on IIS 10 on Windows Server 2016. I do not receive the error when running locally (from VS 2015). I am using v12.0.18.227 of Telerik.Reporting, Telerik.ReportViewer.Mvc, and Telerik.Reporting.Services.WebApi. The process runs using telerikReportViewer-12.0.18.227.js.

This report has additional lookups defined for drop-downs (as partially displayed in "Localhost_working.png").

Greetings.

I'm just learn how to use telerik reporting app, It still run fine when i'm test it on telerik report designer (pic 1), but when i'm run it on browser the parameter input field not show (pic2)..  i already have set parameter to visible on designer tho.

did i miss something ? , can someone help me ? .. i need it ASAP.

Thanks :)

here's my controller 

 

and my view :

 

 

I am trying to use Telerik Reporting in a WPF application based on the Prism MVVM platform.  After much trial an error, I was able to get the report viewer to display the report but could not get the report a second time without closing the window and reopening it.

In Prism, there can only be one Window control, so I had to change the report viewer to a UserControl. 

Has anyone been able to get this to work reliably in Prism?

Hi all

When rendering reports inside a WindowsService the CurrentUICulture is taken from the users configuration and CAN NOT be changed. Within a normal executable this works fine. In general.. To have the localisation depending on the threads culture is not always a good way to control the language output. Is there another way to force localisation for a certain culture? and if not, this would be a big issue to solve!

 

Many thanks

Sascha Bauer
