How to invoke print button of Microsoft report Viewer using c sharp programmatically

Question

How can I invoke the print button of report viewer using c sharp code

Solution 1

Don't.

Print the report programmatically without displaying a preview to the user in the first place. All you have to do is specify the name of a printing device, and the report will be printed automatically without user intervention. Sample code is here: Walkthrough: Printing a Local Report without Preview.

Solution 2

directly copy this code in a class called "Printing" and Call the "Run" method with your reportviewer name as parameter. Example obj.Run(reportviewer1);

But i need to display .rdlc file on report viewer control and print that report file using custom button.How to solve this problem?

[Cody Gray]

@user1146956: You don't have to get rid of the button or the viewer control. But if you want to print the report without user intervention, then you should do it as the above link suggests. Don't try and click the button using code; that'll never work out.

Thanks. Anybody using this code please make this minor change. 1. Update IList to IList<Stream> 2. Update m_streams = new List(); to m_streams = new List<Stream>(); 3. Update m_currentPageIndex < m_streams.Count to m_currentPageIndex < m_streams.Count Ref: Microsoft Tutorial Walkthrough: Printing a Local Report without Preview link
