Is it possible I can detect javascript functions are called when using C# WinForms WebBrowser ? I know it is easy to do it if the javascript functions are my own. But as today I need to browse others' pages, for example, can it be detected when .createElement() or .appendChild() is called?

You might try to inject some Javascript into the control by appending code to the head, similar to this post: How to Inject Javascript in Web Browser Control. The injected code could be a function to monitor events on a particular DOM element.

Thanks for reply. I think I have to override the native functions which I want to detect if I do this way. But I still wonder if WebBrowser can provide me more information as it is the one which executes the javascript functions.

You might have the injected Javascript code call back to C# methos to provide the higher level object in your code. This article describes how to do that: notions.okuda.ca/2009/06/11/…
