ChromiumWebBrowser Methods

Capture page screenshot.

Create the underlying browser. The instance address, browser settings and request context will be used.

Create the underlying CEF browser. The address and request context passed into the constructor will be used. If a Action T delegate was passed into the constructor it will not be called as this method overrides that value internally.

Releases all resources used by the ChromiumWebBrowser object

Releases unmanaged and - optionally - managed resources for the ChromiumWebBrowser

Determines whether the specified object is equal to the current object.

Finalizes an instance of the ChromiumWebBrowser class.

Returns the current CEF Browser Instance

Size of scrollable area in CSS pixels

Serves as the default hash function.

Gets the screen information (scale factor).

Called to retrieve the translation from view coordinates to actual screen coordinates.

Gets the Type of the current instance.

Gets the view rect (width, height) Loads the specified url in the Main Frame. If [!:IsDisposed] is true then the method call will be ignored. Same as calling [!:LoadUrl(string)]

Loads the specified url in the Main Frame. Same as calling [!:Load(string)]

Load the url in the main frame of the browser

Creates a shallow copy of the current Object .

Resize the browser

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.

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.

Returns a string that represents the current object.

Try and get a reference to the IBrowser instance that matches the browserId . Primarily used for geting a reference to the IBrowser used by popups.

Wait for the Browser to finish loading the initial web page.

Add the specified word to the spelling dictionary.

Navigates back, must check CanGoBack before calling this method.

Explicitly close the developer tools window if one exists for this browser instance.

Execute Copy on the focused frame.

Execute Cut on the focused frame.

Execute Delete on the focused frame.

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

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.

Evaluate some Javascript code in the context of this WebBrowser. 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)

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

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).

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 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.

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.

Search for text within the current page.

Navigates forward, must check CanGoForward before calling this method.

Shortcut method to get the browser IBrowserHost.

Gets the default cookie manager associated with the IChromiumWebBrowserBase instance.

Gets a new Instance of the DevTools client for the chromiumWebBrowser instance.

Returns the focused frame for the browser window.

Returns the main (top-level) frame for the browser window.

Retrieve the main frame's HTML source using a Task TResult .

Retrieve the main frame's display text using a Task TResult .

Retrieve the current NavigationEntry . Contains information like HttpStatusCode and SslStatus

Asynchronously gets the current Zoom Level.

Registers and loads a ResourceHandler that represents the HTML content.

Loads html as Data Uri See https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs for details If base64Encode is false then html will be Uri encoded.

Registers and loads a ResourceHandler that represents the HTML content.

Creates a new instance of IRequest with the specified Url and Method = POST and then calls LoadRequest(IRequest) .

Execute Paste on the focused frame.

Opens a Print Dialog which if used (can be user cancelled) will print the browser contents.

Asynchronously prints the current browser contents to the PDF file specified. The caller is responsible for deleting the file when done.

Execute Redo on the focused frame.

Asynchronously registers a Javascript object in this specific browser instance.

Only methods of the object will be availabe.

Registers a Javascript object in this specific browser instance.

Register a ResourceHandler. Can only be used when browser.ResourceHandlerFactory is an instance of DefaultResourceHandlerFactory.

Reloads the page being displayed. This method will use data from the browser's cache, if available.

Reloads the page being displayed, optionally ignoring the cache (which means the whole page including all .css, .js etc. resources will be re-fetched).

If a misspelled word is currently selected in an editable node calling this method will replace it with the specified word.

Execute SelectAll on the focused frame.

Send a mouse wheel event to the browser.

An IWebBrowser extension method that sets the HasParent property used when passing a ChromiumWebBrowser instance to OnBeforePopup(IWebBrowser, IBrowser, IFrame, String, String, WindowOpenDisposition, Boolean, IPopupFeatures, IWindowInfo, IBrowserSettings, Boolean , IWebBrowser )

Set the Document Content for the Main Frame using DevTools Protocol.

Change the ZoomLevel to the specified value. Can be set to 0.0 to clear the zoom level.

Open developer tools in its own window.

Open DevTools using parentControl as the parent control. If inspectElementAtX and/or inspectElementAtY are specified then the element at the specified (x,y) location will be inspected. For resize/moving to work correctly you will need to use the LifeSpanHandler implementation. (Set LifeSpanHandler to an instance of LifeSpanHandler )

Open DevTools using your own Control as the parent. If inspectElementAtX and/or inspectElementAtY are specified then the element at the specified (x,y) location will be inspected.
