I created a report using the Standalone Designer (in .trdp format). In the data connection, I configured it to use a shared connection. From within the Designer, everything works fine — I can preview and export to PDF without any issues.

I then created a console project (code shown below) to try exporting the report to PDF.

In the project's configuration file, I added a connection string to use.

However, when executing the following line:

RenderingResult result = reportProcessor.RenderReport("PDF", sourceReportSource, deviceInfo);

I get an error in the Inner Exception:
Keyword not supported: 'host'.

My PostgreSQL connection string is:
"Host=localhost;Port=5432;Database=crp;Username=postgres;Password=****"

But the connection string is correct — it’s exactly the same one I use in the Standalone Designer, where it works without any problem.

If I embed the connection string directly in the report instead of using a shared connection, everything works fine.

Any idea what could be causing this?

        static void Main(string[] args)
        {
            var builder = new ConfigurationBuilder()
                .SetBasePath(Directory.GetCurrentDirectory())
                .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);

            IConfiguration config = builder.Build();

            string connectionString = config.GetConnectionString("crp");

            string reportName = @"D:\dev\telerik-reporting\reports\report.trdp";

            var reportProcessor = new Telerik.Reporting.Processing.ReportProcessor();

            // set any deviceInfo settings if necessary
            var deviceInfo = new System.Collections.Hashtable();
            var sourceReportSource = new Telerik.Reporting.UriReportSource();
            sourceReportSource.Uri = reportName;
          
            sourceReportSource.Parameters.Add("procedure_id", 6);

            RenderingResult result = reportProcessor.RenderReport("PDF", sourceReportSource, deviceInfo);

            if (!result.HasErrors)
            {
                //string fileName = result.DocumentName + "." + result.Extension;
                string fileName = "file.pdf";
                string path = @"D:\";
                //string path = System.IO.Path.GetTempPath();
                string filePath = System.IO.Path.Combine(path, fileName);

                using (System.IO.FileStream fs = new System.IO.FileStream(filePath, System.IO.FileMode.Create))
                {
                    fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length);
                }
            }

        }

Hi All : 

I am working with Crystal Report to Telerik Report conversion. After I have generated a target trdp file, I found that the parameters in crystal report is not installed to the target report.

I have to manually install the parameters back to the

Here is the original Crystal Report with a parameter. 

The target report :  (No parameter can be found in Report Explorer, I have to install the parameter to make the start the preview(

My Question is : Do I have to manually install the parameter to the target Telerik report after running the conversion tools? 

Thank you in advance.

Problem's Summary : 

Section Formula information lost after Crystal report to Telerik report conversion

What has been done :

I have converted a Crystal report having multiple sections , each section has its own background color controlled by Formula :Also I have used formula to control data formatting (color) in the original Crystal Report.

After I have used the convert it to Telerik Report.

I found that the formula is missing in the converted Telerik Report, there is no any coloring effect in new report. 

My Question is : does the Telerik Crystal Report Converison tools support Formula conversion ?

Thank you

We have a ASP.NET MVC application.

We translated the report viewer as per info provided here to german: Localization of the HTML5 ReportViewer Explained - Telerik Reporting

Now the viewer still shows "Page # of #", and also the dropdown for export still shows english file extensions:

How do we translate these elements as well?

Kind regards.

I am currently using Telerik Reporting version 15.1.21.616 (R2 2021 SP1) in my ASP.NET application. I noticed that the report viewer only exports to the legacy Excel format (.XLS) and there is no option for Excel (.XLSX) in the export formats.

I have checked the Bin directory of my installation, and I do not see the Telerik.Reporting.XlsxRendering.dll assembly, which I understand is required for XLSX export.

Tried to replicate this with prod clone DB on local, works fine. We are not able to find the cause, please help. Below are some information that can help.

RUN apt-get update \
    && apt-get install -y --allow-unauthenticated \
        libc6-dev \
        libgdiplus \
