Hi Hector,

In order to print a report with parameters, without showing the report in the report viewer, you can use the Report Processor. 

We have some good documentation at Print a Report without displaying it in a report viewer. | Telerik Reporting. Specifically scroll down to the WinForms section and take a look at option number three that discusses the Report Processor. 

If you also want to pass parameters we have another documentation page that shows how to do this with the Report Processor. Generating Reports Locally | Telerik Reporting.

For your convenience, I have combined the approaches together into the following example. 

 

// STEP ONE
// Create ReportProcessor 
var reportProcessor = new Telerik.Reporting.Processing.ReportProcessor();


// STEP TWO
//Depending on the report definition choose ONE of the following REPORT SOURCES

// Option 1 CLR (CSharp) report definitions***
var reportSource = new Telerik.Reporting.TypeReportSource();
reportSource.TypeName = reportName;  // reportName is the Assembly Qualified Name of the report

// Option 2- If you have a TRDP report, use this
//var reportSource = new Telerik.Reporting.UriReportSource();
//reportSource.Uri = "MyReport.trdp";

// Option 3, if you have an instance report, use this
//var reportSource = new Telerik.Reporting.InstanceReportSource();
//reportSource.ReportDocument = new Report1();



// STEP THREE 
//Set any parameters
reportSource.Parameters.Add("SalesYear", 2007);
reportSource.Parameters.Add("SalesPerson", "John Doe");


// STEP FOUR
//Print the report. See docs https://docs.telerik.com/reporting/knowledge-base/print-a-report-programmatically
reportProcessor.PrintReport(reportSource, new PrinterSettings());

 

I understand I the code example is in C#, you can use this code converter to get it in VB. Code Converter C# to VB and VB to C# – Telerik.
