ChromiumWebBrowser Methods |
The ChromiumWebBrowser type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | CaptureScreenshotAsync |
Capture page screenshot.
|
| CreateBrowser |
Create the underlying browser. The instance address, browser settings and request context will be used.
|
| CreateBrowserAsync |
Create the underlying CEF browser. The address and request context passed into the constructor
will be used. If a ActionT delegate was passed
into the constructor it will not be called as this method overrides that value internally.
|
| Dispose |
Releases all resources used by the ChromiumWebBrowser object
|
 | Dispose(Boolean) |
Releases unmanaged and - optionally - managed resources for the ChromiumWebBrowser |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize |
Finalizes an instance of the ChromiumWebBrowser class.
(Overrides ObjectFinalize.) |
| GetBrowser |
Returns the current CEF Browser Instance
|
| GetContentSizeAsync |
Size of scrollable area in CSS pixels
|
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetScreenInfo |
Gets the screen information (scale factor).
|
| GetScreenPoint |
Called to retrieve the translation from view coordinates to actual screen coordinates.
|
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GetViewRect |
Gets the view rect (width, height)
|
| Load |
Loads the specified url in the Main Frame.
If [!:IsDisposed] is true then the method call will be ignored.
Same as calling [!:LoadUrl(string)] |
| LoadUrl |
Loads the specified url in the Main Frame.
Same as calling [!:Load(string)] |
| LoadUrlAsync |
Load the url in the main frame of the browser
|
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ResizeAsync |
Resize the browser
|
| ScreenshotAsync | Obsolete.
Starts a task that waits for the next rendering from Chrome.
Chrome also renders the page loading, so if you want to see a complete rendering,
only start this task once your page is loaded (which you can detect via FrameLoadEnd
or your own heuristics based on evaluating JavaScript).
It is your responsibility to dispose the returned Bitmap.
The bitmap size is determined by the Size property set earlier.
|
| ScreenshotOrNull |
Immediately returns a copy of the last rendering from Chrome,
or null if no rendering has occurred yet.
Chrome also renders the page loading, so if you want to see a complete rendering,
only start this task once your page is loaded (which you can detect via FrameLoadEnd
or your own heuristics based on evaluating JavaScript).
It is your responsibility to dispose the returned Bitmap.
The bitmap size is determined by the Size property set earlier.
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| TryGetBrowserCoreById | |
| WaitForInitialLoadAsync |
Wait for the Browser to finish loading the initial web page.
|
 | WaitForNavigationAsync |
This resolves when the browser navigates to a new URL or reloads.
It is useful for when you run code which will indirectly cause the browser to navigate.
A common use case would be when executing javascript that results in a navigation. e.g. clicks a link
This must be called before executing the action that navigates the browser. It may not resolve correctly
if called after.
|
Extension Methods| Name | Description | |
|---|---|---|
 | AddWordToDictionary |
Add the specified word to the spelling dictionary.
(Defined by WebBrowserExtensions.) |
| Back |
Navigates back, must check CanGoBack before calling this method.
(Defined by WebBrowserExtensions.) |
| CloseDevTools |

(Defined by WebBrowserExtensions.) |
| Copy |
Execute Copy on the focused frame.
(Defined by WebBrowserExtensions.) |
| Cut |
Execute Cut on the focused frame.
(Defined by WebBrowserExtensions.) |
| Delete |

| 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.

| 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.
