It's not easy. You need to create a custom version of the WebBrowser control, override the CreateWebBrowserSiteBase method, and hook up your own implementation of the unmanaged IDownloadManager interface[^].

There's a sample on MSDN Code[^] which implements a global download manager in C#.

This question on StackOverflow[^] suggests that it's possible to adapt that sample to work with the WebBrowser control.

But there doesn't seem to be a complete working example. The download links in the SO thread are broken.

You might be able to combine the code from the sample with the information in the SO thread to do what you need.
