Extension Methods| Name | Description | |
|---|---|---|
 | AddWordToDictionary |

(Defined by WebBrowserExtensions.) |
| Back |

(Defined by WebBrowserExtensions.) |
| CloseDevTools |

(Defined by WebBrowserExtensions.) |
| Copy |

(Defined by WebBrowserExtensions.) |
| Cut |

 | DestroyWindow |
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.
(Defined by WebBrowserExtensions.) |
| EnsureObjectBoundAsync |
Make sure an object is bound in javascript. Executes against the main frame
(Defined by JavascriptBindingExtensions.) |
| EvaluateScriptAsPromiseAsync |
Evaluate Javascript in the context of the MainFrame of the ChromiumWebBrowser. The script will be executed
asynchronously and the method returns a Task encapsulating the response from the Javascript. The result of the script execution
in javascript is Promise.resolve so even no promise values will be treated as a promise. Your javascript should return a value.
The javascript will be wrapped in an Immediately Invoked Function Expression.
When the promise either trigger then/catch this returned Task will be completed.
(Defined by WebBrowserExtensions.) |
| EvaluateScriptAsync(String, Object) | Overloaded.

returns a Task encapsulating the response from the Javascript This simple helper extension will encapsulate params in single
quotes (unless int, uint, etc)
(Defined by WebBrowserExtensions.) |
| EvaluateScriptAsync(String, NullableTimeSpan, Boolean) | Overloaded.
Evaluate Javascript in the context of this Browsers Main Frame. The script will be executed
asynchronously and the method returns a Task encapsulating the response from the Javascript
(Defined by WebBrowserExtensions.) |
| EvaluateScriptAsync(NullableTimeSpan, String, Object) | Overloaded.
Evaluate Javascript code in the context of this WebBrowser using the specified timeout. The script will be executed
asynchronously and the method returns a Task encapsulating the response from the Javascript This simple helper extension will
encapsulate params in single quotes (unless int, uint, etc).
(Defined by WebBrowserExtensions.) |
| ExecuteDevToolsMethodAsync |
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.
(Defined by DevToolsExtensions.) |
| ExecuteScriptAsync(String) | Overloaded.
Execute Javascript in the context of this Browsers Main Frame. As the method name implies, the script will be executed
asynchronously, and the method therefore returns before the script has actually been executed.
(Defined by WebBrowserExtensions.) |
| ExecuteScriptAsync(String, Object) | Overloaded.
Execute Javascript code in the context of this Browser. As the method name implies, the script will be executed
asynchronously, and the method therefore returns before the script has actually been executed. This simple helper extension
will encapsulate params in single quotes (unless int, uint, etc)
(Defined by WebBrowserExtensions.) |
| ExecuteScriptAsyncWhenPageLoaded |
Execute Javascript code in the context of this Browsers Main Frame. This extension method uses the LoadingStateChanged event. As the
method name implies, the script will be executed asynchronously, and the method therefore returns before the script has
actually been executed.
