C# Download Silently With Webbrowser Control (No Dialog Box)

I do this: 1. Navigate with webbrowser control to a website 2. Click on a button on webbrowser, file download popup appears you can choose Open, Save, Cancel I need this: 1. Navigate with webbrowser control to a website 2. Click on a button on webbrowser, file downloads silently, hidden (No Popup, No File Download dialog) I heard you can do this with IDownloadManager. ***Must be in Webbrowser!*** ***Do It in the same instance This means when I click the button do not cancel and copy the url and download via some httpwebrequest, It must download it silently from the moment I click the button via Webbrowser!*** You can take a look at the demo project I found online (Attached it) if you go to [login to view URL] and download it will silently download it.
