Hi,

We do not have the equivalent of this event in the current build. The reason is because our EO.WebBrowser has a multi-process architecture (inherited from Chrome), so all the keyboard events actually occurs in a child process rather in your process. To support hotkeys, we do forward key down event from the child process to your process. However currently we do not forward key up event. What we can do is to add a key up event similar to this one:

Note that the event argument contains the raw data of a Windows message. You can search Windows SDK on those two messages (WM_KEYDOWN and WM_KEYUP) to get the exact meaning of WParam and LParam argument. Another key difference is you will not be able to cancel these key event. If you wish to cancel key events, you can inject JavaScript code into the WebView (either through WebView.EvalScript or WebView.JSInitCode) and then handle the keyboards event through JavaScript. In your JavaScript code, you will be able to cancel the event directly or even call .NET side code to determine whether you need to cancel the event.

Thanks!

Great. Please feel free to let us know if there is anything else.
