Handle back command in custom ContextMenuHandler
The Next CEO of Stack OverflowHow to handle mouse click in CefSharp to navigate back and forwardCustom libcef.dll path with CefSharpCefSharp custom SchemeHandlerCefSharp: Injecting custom CSS File using a custom schemeAfter upgrading from CEFSharp 57 to 63 ChromeDriver “get” command does not block until the page load is completeChromiumFx / Cef How to send custom IPC message to renderer process and execute custom c# codeHow do you display a custom message with CefSharp when JavaScript handles OnBeforeUnload?How to mark F10 key as handled in CefSharp for WPF?How do I add a 'Access-Control-Allow-Origin' to a requested resource with a custom scheme with CefSharpWhy do CefSharp custom context menu commands not work most of the time?
I have implemented a custom ContextMenuHandler:
public bool OnContextMenuCommand(IWebBrowser chromiumWebBrowser, IBrowser browser, IFrame frame, IContextMenuParams parameters, CefMenuCommand commandId, CefEventFlags eventFlags)
if (commandId == (CefMenuCommand)26501)
// custom logic
return true;
if (commandId == CefMenuCommand.Back)
Dispatcher.CurrentDispatcher.Invoke(() =>
if (chromiumWebBrowser.CanGoBack) chromiumWebBrowser.Back();
);
return true;
The custom command works as expected. However, the Back-command doesn't work. The thread doesn't have access to the browser instance:
The calling thread cannot access this object because a different
thread owns it.
Omitting the dispatching logic doesn't solve the problem.
- Do I need to explicitly handle the Back-command using the if-statement (will be refactored to swicth-case, no worries)
- If yes, how?
- In general, how can I get the dispatcher of the web browser instance?

Using Dispatcher.CurrentDispatcher won't always return the UI dispatcher, cast IWebBrowser to it's concrete implementation like github.com/cefsharp/CefSharp/blob/master/CefSharp.Wpf.Example/…

The solution is to not include the Back-command in the switch-case and return false instead.
public bool OnContextMenuCommand(IWebBrowser chromiumWebBrowser, IBrowser browser, IFrame frame, IContextMenuParams parameters, CefMenuCommand commandId, CefEventFlags eventFlags)
if (commandId == (CefMenuCommand)26501)
// custom logic
return true;
return false;
