Print RDLC file without showing print preview from Form button click

printingrdlcreportviewer

I've got a C#4.0 WinForm with a button click for Printing. In the Form Load event, I populate a custom object and stick that object into a list of that object. The object maps directly to the RDLC as a datasource and if I use the Report Viewer, I can see my RDLC file populated correctly. I found a link at MSDN to do this (http://msdn.microsoft.com/en-us/library/ms252091.aspx), but it blows up on the Export method.

Does anyone know of any good examples of how to print an RDLC file without using ReportViewer to preview the file? I just want to hit a button and have my List bind to the RDLC file (which I've already got working) and print directly to the printer.

any ideas?

Okay, so the link at Walkthrough: Printing a Local Report without Preview does actually work perfectly for my need to print a RDLC file without popping up the Print dialogue box. The mistake I made was naming my ReportDataSource. As in the example, MSDN names its ReportDataSource as "Sales" which matches the name of the DataSet in the RDLC XML codebehind. I had made the mistake of naming my ReportDataSource "Sale" which was causing the two not to be in sync and not print.

Problem solved!

C# – Print PDF from ASP.Net without preview

Finally I made it, but I had to use an IFRAME, I defined an IFrame in the aspx and didn't set the src property, in the cs file I made generated the pdf file and set the src property of the iFrame as the generated pdf file name, like this;

Document pdf = new Document(PageSize.LETTER);
PdfWriter writer = PdfWriter.GetInstance(pdf, 
new FileStream(Request.PhysicalApplicationPath + "~1.pdf", FileMode.Create));
pdf.Open();

//This action leads directly to printer dialogue
PdfAction jAction = PdfAction.JavaScript("this.print(true);\r", writer);
writer.AddJavaScript(jAction);

pdf.Add(new Paragraph("My first PDF on line"));
pdf.Close();

//Open the pdf in the frame
frame1.Attributes["src"] = "~1.pdf";

And that made the trick, however, I think that i should implement your solution Stefan, the problem is that I'm new to asp.net and javascript and if I don't have a complete source code I could not code your suggestion but at least is the first step, I was very surprised how much code in html and javascript i need to learn. Thnx.
