ReportProcessor

Class

Represents the object responsible for printing and rendering Reports.

Definition

Namespace:Telerik.Reporting.Processing

Assembly:Telerik.Reporting.dll

Syntax:
C#
public sealed class ReportProcessor

Inheritance: objectReportProcessor

Constructors

ReportProcessor()

Initializes a new instance of the ReportProcessor class.

C#
public ReportProcessor()

Properties

PrintController

PrintController

Specifies a print controller to be used when printing a Report. If a null value is specified, a default print controller is used, which displays the Print Progress dialog.

C#
public PrintController PrintController { get; set; }

If you need a better control over the printing process, or simply to customize the appearance of the print UI, you should specify a custom print controller to this method.

This example shows how to customize the title of the Print Progress dialog with a custom provided print controller.
cs
var reportName = "Telerik.Reporting.Examples.CSharp.Dashboard, CSharp.ReportLibrary";

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

// Create a custom print controller based on the StandardPrintController with title: Print Progress
System.Drawing.Printing.PrintController standardPrintController =
    new System.Drawing.Printing.StandardPrintController();

System.Drawing.Printing.PrintController customPrintController =
    new System.Windows.Forms.PrintControllerWithStatusDialog(standardPrintController, "Print Progress");

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


reportProcessor.PrintController = customPrintController;

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

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

reportProcessor.PrintReport(typeReportSource, printerSettings);
vb
Dim reportName = "ReportCatalog, VB.ReportLibrary"

' Obtain the settings of the default printer
Dim printerSettings As New System.Drawing.Printing.PrinterSettings

' Create a custom print controller based on the StandardPrintController with title: Print Progress 
Dim standardPrintController As New System.Drawing.Printing.StandardPrintController Dim customPrintController As New System.Windows.Forms.PrintControllerWithStatusDialog(standardPrintController, "Print Progress")

' Create a report source to pass the report to the report processor
Dim typeReportSource As New Telerik.Reporting.TypeReportSource()

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

' Print the report using the custom print controller
Dim reportProcessor As New Telerik.Reporting.Processing.ReportProcessor reportProcessor.PrintController = customPrintController reportProcessor.PrintReport(typeReportSource, printerSettings)

Methods

GetAvailableRenderingExtensions()

IReadOnlyList<string>

Gets a read-only collection of available rendering extension names.

C#
public static IReadOnlyList<string> GetAvailableRenderingExtensions()
Returns:

IReadOnlyList<string>

A read-only collection of strings representing the names of the available rendering extensions (e.g., "PDF", "XLSX", "DOCX").

Print(IReportDocument, PrinterSettings)

Prints a report document using the specified printer settings.

C#
[Obsolete("The static (Shared) ReportProcessor.Print method is now obsolete. Please create an instance of the ReportProcessor class and use the PrintReport method.")]
public static void Print(IReportDocument reportDocument, PrinterSettings printerSettings)
Parameters:reportDocumentIReportDocument

Specifies an instance of a report document to print. Both Report and ReportBook documents are supported.

printerSettingsPrinterSettings

Specifies the printer settings to be used when printing the document. If null or invalid settings are specified, the Print Dialog appears.

To prevent the Print Dialog from appearing, you should specify valid printer settings to this method.

This example illustrates how to prevent the standard Print Dialog from appearing in a batch print operation or when printing from a service.
csharp
// Create an instance of the report to print.
IReportDocument reportDocument = new MyReport();
// Obtain the settings of the default printer.
PrinterSettings printerSettings = new PrinterSettings();
// Adjust the printer settings if necessary...

// Print the report using the printer settings.
ReportProcessor.Print(reportDocument, printerSettings);
csharp
' Create an instance of the report to print.
Dim reportDocument As IReportDocument = New MyReport()
' Obtain the settings of the default printer.
Dim printerSettings As New PrinterSettings()
' Adjust the printer settings if necessary...

' Print the report using the printer settings.
ReportProcessor.Print(reportDocument, printerSettings)
