Version 79.1.350

The ChromiumWebBrowser 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 your running with settings.MultiThreadedMessageLoop = false, then they'll be the same thread).
Public eventContextMenuClosing
Occurs just before any context menu on the element is closed.
(Inherited from FrameworkElement.)
Public eventContextMenuOpening
Occurs when any context menu on the element is opened.
(Inherited from FrameworkElement.)
Public eventDataContextChanged
Occurs when the data context for this element changes.
(Inherited from FrameworkElement.)
Public eventDragEnter
Occurs when the input system reports an underlying drag event with this element as the drag target.
(Inherited from UIElement.)
Public eventDragLeave
Occurs when the input system reports an underlying drag event with this element as the drag origin.
(Inherited from UIElement.)
Public eventDragOver
Occurs when the input system reports an underlying drag event with this element as the potential drop target.

Occurs when the input system reports an underlying drop event with this element as the drop target.

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.
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.
