Hi kcauchi,

I do not think to open a PDF file in a WebBrowser control is a really good idea, for the WebBrowser control would not ensure to open the PDF file properly.

I want to recommend you to use the Adobe Acrobat Control for ActiveX to load the PDF file, you can drag and drop the ActiveX control to your C# windows form in the design mode from the Toolbox, and then you can load the file like the following code snippet.

I'm not aware of any ASP.NET PDF Viewer controls off the top of my head, but are you sure you need one? Most users these days will have a browser plugin for displaying PDF files - why not try streaming the PDF file straight back to the browser? For users without a plugin, you can provide a link to Adobe Acrobat.

web browser control meaning its windows not web
