Hello,

You can use below code to achive custom size,

using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
using System.Drawing.Printing;

public void SetCustomPaperSizeToCrystalReportViewer(CrystalReportViewer crystalReportViewer, ReportDocument reportDocument)
{

    PaperSize customPaperSize = new PaperSize("CustomSize", 850, 1100); 

    PrinterSettings printerSettings = new PrinterSettings();
    printerSettings.DefaultPageSettings.PaperSize = customPaperSize;
    

    reportDocument.PrintOptions.PrinterName = printerSettings.PrinterName;
    

    reportDocument.PrintOptions.PaperSize = PaperSizeEnum.PaperLetter; 

    reportDocument.PrintOptions.Orientation = CrystalDecisions.Shared.Orientation.Landscape; 
    

    crystalReportViewer.ReportSource = reportDocument;
}

Thank For Answering
But Your Given Solution Not Working Properly.

reportDocument.PrintOptions.PaperSize = (CrystalDecisions.Shared.PaperSize)customPaperSize;

This one give error like "Cannot Convert type'System.Drawing.Printing.PaperSize''to "CrystalDecisions.Shared.PaperSize""

=>The error you are encountering occurs because CrystalDecisions.Shared.PaperSize.PaperCustom is not a valid predefined value in CrystalDecisions.Shared.PaperSize. Unfortunately, CrystalDecisions.Shared.PaperSize does not have direct support for custom paper sizes.
 

Hi Gross Account,

To set a custom paper size for a printer in CrystalReportViewer, you can utilize the PrinterSettings class in C#. Below is a step-by-step approach to achieve this:

1. Create a Custom Paper Size: First, define your custom paper size using the PaperSize class.

2. Assign the Custom Paper Size to the PrinterSettings: Use the PrinterSettings object to set the custom paper size.

3. Set the PrinterSettings in the ReportDocument: Finally, apply the settings to your Crystal Report.

4. using System.Drawing.Printing;
   using CrystalDecisions.CrystalReports.Engine;
   using CrystalDecisions.Shared;
   
   // Create a new instance of the report
   ReportDocument reportDocument = new ReportDocument();
   reportDocument.Load("YourReportPath.rpt");
   
   // Define a custom paper size
   PaperSize customPaperSize = new PaperSize("CustomSize", 850, 1100); // Width and Height in hundredths of millimeters
   
   // Create PrinterSettings and assign the custom paper size
   PrinterSettings printerSettings = new PrinterSettings();
   printerSettings.DefaultPageSettings.PaperSize = customPaperSize;
   
   // Set the PrinterSettings to the report
   reportDocument.PrintOptions.PrinterName = printerSettings.PrinterName;
   reportDocument.PrintOptions.PaperSize = (CrystalDecisions.Shared.PaperSize)customPaperSize;
   
   // Print the report
   reportDocument.PrintToPrinter(printerSettings, new PageSettings(), false);
   

   This code snippet will set the custom paper size for the printer when printing from the CrystalReportViewer. Ensure that the printer supports the specified paper size to avoid any printing issues.
