Version 118.6.80

The IWpfWebBrowser type exposes the following members.

Events
  NameDescription
Public eventConsoleMessage
Event handler for receiving Javascript console messages being sent from web pages. It's important to note this event is fired on a CEF UI thread, which by default is not the same as your application UI thread. It is unwise to block on this thread for any length of time as your browser will become unresponsive and/or hang.. To access UI elements you'll need to Invoke/Dispatch onto the UI Thread. (The exception to this is when you're running with settings.MultiThreadedMessageLoop = false, then they'll be the same thread).
(Inherited from IChromiumWebBrowserBase.)
Public eventFrameLoadEnd
Event handler that will get called when the browser is done loading a frame. Multiple frames may be loading at the same time. Sub-frames may start or continue loading after the main frame load has ended. This method will always be called for all frames irrespective of whether the request completes successfully. It's important to note this event is fired on a CEF UI thread, which by default is not the same as your application UI thread. It is unwise to block on this thread for any length of time as your browser will become unresponsive and/or hang.. To access UI elements you'll need to Invoke/Dispatch onto the UI Thread.
(Inherited from IChromiumWebBrowserBase.)
Public eventFrameLoadStart
Event handler that will get called when the browser begins loading a frame. Multiple frames may be loading at the same time. Sub-frames may start or continue loading after the main frame load has ended. This method may not be called for a particular frame if the load request for that frame fails. For notification of overall browser load status use OnLoadingStateChange instead. It's important to note this event is fired on a CEF UI thread, which by default is not the same as your application UI thread. It is unwise to block on this thread for any length of time as your browser will become unresponsive and/or hang.. To access UI elements you'll need to Invoke/Dispatch onto the UI Thread.
