Hi,
I'm having some trouble with the kendo report configuration.

My reports run perfectly on localhost, but when i deploy my application the reports fail to load. After some investigation i realised that it is an issue related with permissions asi get the following exception : "Access to the path 'C:\Windows\TEMP\Html5App\10.2.16.1025\LCT\value.dat' is denied."

I have looked at the documentation and at similar questions such as this one (http://www.telerik.com/forums/cache-file-error-not-fixed-with-config-entry), and  tried different configurations but unfortunately still did not manage to overcome the issue. 

I know this issue is related to cache configuration, i read the documentation carefully, and this page (http://docs.telerik.com/reporting/using-telerik-reporting-in-applications-rest-service-cache-management-overview) sugests that cache management is mandatory.  However on the documentation its not clear why?  Also is not clear  what is actually being cached?? Is it a compiled version of the report template which recieves parameters and dysplay the data,  or is it  the actual final report which is displayed? 

Because if it is the later then is s there a way i can publish my reports without caching? Because i cannot have a cached instance of each invoice which is displayed and printed only once. And is not really advantageous for me as most of the reports will rarely will be called twice with the same parameters

We are using Telerik Reports 10.2.16.914

In the attachment you will see errors we are getting. 

here is the content of Output(Debug)

An exception has occurred while processing 'graph1' item:

We use web report viewer, it is telerikReportViewer-10.2.16.914.js

This is a part where we believe that timeout was increased. 

 public partial class LeastActiveDispatchers_Avg : Telerik.Reporting.Report
    {
        public LeastActiveDispatchers_Avg( )
        {
            InitializeComponent( );
            endpointSummaryDataSource.CommandTimeout = 600;
        }
    }

It is fills that the real that report is using timeout from 15 to 30 seconds instead of 10 minutes. 

The break point is not being hit when running in debug mode. So I have two questions I need help. 

1. How to debug a report? 

2. How to set timeout?

Hello,

I have created a report in Telerik report designer R3 2016, and to make my report multilingual i have created a parameter named pCulture to which user is passing culture name(eg. French(fr-FR), portuguese (pt-PT), English(en-EN)) which is working fine.

How my function is working :

TelerikReportResources.MultilanguageTelerikReport.GetCultureSpecificString(Parameters.pCulture.Value,"Key") //It is User defined function

The "key" will be translated from .net side in any language which has been entered by user in pCulture parameter.

Now the problem is :

I have Pie chart in my report which is showing weekdays, so here i have to compare pCulture parameter first, either it is french, Portuguese or English and again in particular language have to compare for the weekdays.as given below:

if the Parameters.pCulture.Value="fr-FR" and dayNameOfweek="Monday" then Monday="Lundi"

if the Parameters.pCulture.Value="fr-FR" and dayNameOfweek="Tuesday" then Monday="Mardi"

elseif the Parameters.pCulture.Value="fr-FR" and dayNameOfweek="Wednesday" then Monday="Mercredi"

elseif the Parameters.pCulture.Value="fr-FR" and dayNameOfweek="Thursday" then Monday="Jeudi"

elseif the Parameters.pCulture.Value="fr-FR" and dayNameOfweek="Friday" then Monday="Vendredi"

elseif the Parameters.pCulture.Value="fr-FR" and dayNameOfweek="Saturday" then Monday="samedi"

elseif the Parameters.pCulture.Value="fr-FR" and dayNameOfweek="Sunday" then Monday="dimanche"

same for Portuguese and English.so according to my logic i will have to create 21 elseif for this.

please guide me.

Hello,

I have a website project that prints reports fine running locally but once loaded to a webserver it starts to throw exception "Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application."

Code I'm using to print report is:

    public void PrintReport(Report report, string printerName)
    {
        Telerik.Reporting.Processing.ReportProcessor reportProcessor = new Telerik.Reporting.Processing.ReportProcessor();
        InstanceReportSource instanceReportSource = new InstanceReportSource();
        PrinterSettings psettings = new PrinterSettings {
            PrinterName = printerName
        };

        instanceReportSource.ReportDocument = report;
        reportProcessor.PrintReport(instanceReportSource, psettings);
    }

I do need to signify exact printer to print to as well as it needs to be silent.  How come this only works locally?

I purchased DevCraft Complete and I'd like to get started with reporting. Does Telerik provide any tutorials for getting started with Reporting? I was able to find one tutorial but that was from 4 years ago. I'm sure a lot has changed since then.

I'm really having a hard time getting Telerik Reports to do anything for me.  The latest version says it's .NET Core but the first thing you do is remove .NET Core from the project and add the full framework.

I have an existing application that is entirely .NET Core.  This includes front-end, EF, the API, and the middle-tier.  All my business models are .NET Core assembly.

We are not going to add the full framework to any of our existing projects.  Therefore Telerik Reporting must be in assembly which will have a front-end used solely for showing reports selected by the user in our main web application.  However, since all the business models are in a Core only assembly, and I have no interest in duplicating all the models just for this Telerik only project, I am hoping that I can feed the report JSON retrieved from the API.

Is this possible?  I'm looking at the datasources and I'm not clear if one of those would work, or if there is another way to provide this data.

Can we pass html elements such as <button onclick = "dosomething()"> </button> to  htmltextbox in html5 report viewer

Hello,

I'm trying to create new table report based on ObjectDatasource and as result I get empty table duplicates. Please see Screenshot_1.png

Could you please advise how the issue could be solved?
