InfoPath Dev

In infopath 2010  form, when image button/hyperlink is clicked I need to open pdf file with specific page in new browser window. I tried by providing url to image button, but its asking me to save pdf instead of opening in browser. If possible i want to do this without custom code. Can someone guide me with this..

This is an interesting question - I did a quick search to see if there were some specific parameters to use that would force PDFs to open in the browser rather than download, and I'm not finding anything - it seems to be a user setting. Are you including the page number in the URL? i.e. - http://www.URL.com/FILENAME.pdf#page=5

yes am including page#5 in the url..
