I am little confused as to how reporitng source works I just need to be able to bind this list to the the report and was wondering how I might do this.

Hi,

I'm trying to implement the Telerik reporting engine using Azure functions. When I provide an objectdatasource the ReportProcessor renders with an Exception

The assembly "MyAssembly" is not permitted to be used by an ObjectDataSource section of your application configuration file.

I assume thisis related to AssemblyReferences configuration specified here: https://docs.telerik.com/reporting/objectdatasource#configuration

Azure functions do not support web.config files. Is there any other option to set the AssemblyReferences?

Thanks
Matthias

Hi,

I am not sure that I have designed my report the most efficient way but that is another issue, I currently have a report that displays multiple different parameters from a database each displayed in their own table with their own sqldatasource.  This all works fine but like I say, I don't think this is the most efficient way.

 

My issue is, there is a requirement for one of the parameters to only be displayed depending on the value of another parameter in another table.  How would I go about doing this?

 

Any help/pointers in the right direction would be greatly appreciated.

 

Thanks

Hi Telerik team,

I know actually there is no native support for localization in standalone report (contrary to visual studio report).

I wondered if this feature will be implemented in a near future or if it is not planned for the moment.

Thanks a lot for your feedback.

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>
        <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="31bf3856ad364e35" />
        <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:

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,

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.
