Hi,

I have a problem when I  try to print report in controller. The thing is; it is working locally but when I deploy the project to iss I am getting error message says; "System.InvalidOperationException: No or invalid printer error on IIS server."


// Obtain the settings of the default printer
                System.Drawing.Printing.PrinterSettings printerSettings
                    = new System.Drawing.Printing.PrinterSettings();

                // The standard print controller comes with no UI
                System.Drawing.Printing.PrintController standardPrintController =
                    new System.Drawing.Printing.StandardPrintController();

                // Print the report using the custom print controller
                Telerik.Reporting.Processing.ReportProcessor reportProcessor
                    = new Telerik.Reporting.Processing.ReportProcessor();

                reportProcessor.PrintController = standardPrintController;

                    Telerik.Reporting.TypeReportSource typeReportSource =
                        new Telerik.Reporting.TypeReportSource();

                    //// reportName is the Assembly Qualified Name of the report
                    //typeReportSource.TypeName = reportName;

                // Create a new report source pointing to report definition
                var reportSource = new UriReportSource();
                reportSource.Uri = entity.ReportName;



                foreach (var i in entity.Parameters)
                {
                    reportSource.Parameters.Add(new Parameter(i.Key, i.Value));
                }


                    reportProcessor.PrintReport(reportSource, printerSettings);                    

                return null;

 

Please suggest,

Thanks

Hi guys,

I have deleted the header row of a table by mistake and now the function with print on every page is not working obviously.
Is it possible to delcare a 'normal' row as the header? Or a function to add a new header row?
I cant find any functionality to this.
But it would be really much work to build the table new from scrap.

Also I think I will still have a problem. I have the following situation:
I have the situation where I need the GroupHeaders and GroupFooters on every page.
Not just the ColumnHeaders. I don't know if this is possible.

Greetings

I want to bind for example cars to one table and houses to another table. In screenshot A, I am trying to bind a table column to an array of models in the cars object, but the telerik support designer doesn't allow me to see the models and select it. All is shows that its a system.Object. Am I doing something wrong? I am using a json data source like this (I am aware that the json is in single quotes, that's not a problem. I have using json data with double quotes and still the same problem):
JsonDataSource:
{
  'name': 'john',
  'age': 146,
  'cars': [{
    'model': 'Ford89',
    'price': 50
  },{
    'model': 'BMW',
    'price': 42
  }],
  'houses': [{
    'location': 'los angelos',
    'cost': 505
  },{
    'location': 'sunny town',
    'cost': 505
  }]
}

Can somebody help me? Thank you.

Dear Telerik support team,  

Is Telerik using any Log4j as a logging tool? Please kindly confirm this to us. Thanks

 

Hi,

I am using Telerik.Reporting library (15.2.21.1110) in Blazor Server application.
The report was created in standalone Report designer (.trdp).
I can display that report in the Blazor ReportViewer component. 
When running the web app on Windows I can export to PDF, DOCX via the ReportViewer and also without the REST service using Telerik.Reporting.Processing.ReportProcessor.RenderReport().


The problem occurs when building the application as Docker RedHat based image. 
In that case the DOCX works but the PDF fails in both scenarios (REST report service and ReportProcessor) throwing eventually System.OperationCanceledException.
Dockerfile instructs to use RedHat UBI8 base image and install GDI+ Win library replacement for Unix systems (glibc-devel, libicu, libX11-devel, libgdiplus).

Do you have any suggestions what could be wrong?

In the aftermath of the Log4J security breach, we need to be sure that all vulnerable components are patched.

I guess there are no Java components and hence not Log4J involved in any of Telerik's components, but can this please be confirmed?

I am facing the issue with parameterized report with PostgreSQL database in Angular .NET Core application.
I have configured everything as per the documentation. I tried lots to resolve this issue at my end but parameterized report not loading details when passing params from angular, If I used to designer preview it is fine. For testing purpose, I changed the database to SQL Server and same code and configuration works. I needs working solution for this with PostgreSQL database for parameterized reports. If anyone worked with parameterized report with PostgreSQL database in Angular .NET Core application. Please suggest solution for it. I am sharing my code configuration and report, please have a look.

Parameter passing from angular:

Please suggest any solution for it.

In standalone designer, R3 2021.

I have a table being displayed as shown below.

How do I get the time cell for second row to be the same size as the treatment text?

The detail section and both cell height parameters are all the same
