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).

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.

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.

Event handler that will get called when the message that originates from CefSharp.PostMessage

Event handler that will get called when the resource load for a navigation fails or is canceled. 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.

Event handler that will get called when the Loading state has changed. This event will be fired twice. Once when loading is initiated either programmatically or by user action, and once when loading is terminated due to completion, cancellation of failure. 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.

Raised every time OnPaint(PaintElementType, Rect, IntPtr, Int32, Int32) is called. You can access the underlying buffer, though it's preferable to either override OnPaint(Boolean, Rect, IntPtr, Int32, Int32) or implement your own IRenderHandler as there is no outwardly accessible locking (locking is done within the default IRenderHandler implementations). 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

Event handler for changes to the status message. 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).

Raised every time OnVirtualKeyboardRequested(IBrowser, TextInputMode) is called. 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

Manually call https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-destroywindow passing in the handle returned from GetWindowHandle. This method can be used to manually close the underlying CefBrowser instance. This will avoid the WM_Close message that CEF sends by default to the top level window. (Which closes your application). This method should generally only be used in the WinForms version.

Make sure an object is bound in javascript. Executes against the main frame

Execute a method call over the DevTools protocol. This is a more structured version of SendDevToolsMessage. ExecuteDevToolsMethod(IBrowserHost, Int32, String, JsonString) can only be called on the CEF UI Thread, this method can be called on any thread. See the DevTools protocol documentation at https://chromedevtools.github.io/devtools-protocol/ for details of supported methods and the expected parameters dictionary contents. See the SendDevToolsMessage documentation for additional usage information.

Execute some Javascript code in the context of this WebBrowser. As the method name implies, the script will be executed asynchronously, and the method therefore returns before the script has actually been executed.
