Create a new WebView2 WinForms control.After construction the CoreWebView2 property is null.Call EnsureCoreWebView2Async(CoreWebView2Environment) to initialize the underlying CoreWebView2.

Returns true if the webview can navigate to a previous page in thenavigation history via the GoBack() method.This is equivalent to the CanGoBack.If the underlying CoreWebView2 is not yet initialized, this property is false.

Returns true if the webview can navigate to a next page in thenavigation history via the GoForward() method.This is equivalent to the CanGoForward.If the underlying CoreWebView2 is not yet initialized, this property is false.

The underlying CoreWebView2. Use this property to perform more operations on the WebView2 content than is exposedon the WebView2. This value is null until it is initialized. You can force the underlying CoreWebView2 toinitialize via the InitializeAsync method.

Protected CreateParams property. Used to set custom window styles to the forms HWND.

Gets or sets a bag of options which are used during initialization of the control's CoreWebView2.This property cannot be modified (an exception will be thrown) after initialization of the control's CoreWebView2 has started.

The default background color for the WebView.

The Source property is the URI of the top level document of theWebView2. Setting the Source is equivalent to calling Navigate(String).Setting the Source will trigger initialization of the CoreWebView2, if not already initialized.The default value of Source is null, indicating that the CoreWebView2 is not yet initialized.

The zoom factor for the WebView.

Cleans up any resources being used.

Explicitly trigger initialization of the control's CoreWebView2.

Executes the provided script in the top level document of the WebView2.This is equivalent to ExecuteScriptAsync(String).

Navigates to the previous page in navigation history.This is equivalent to GoBack().If the underlying CoreWebView2 is not yet initialized, this method does nothing.

Navigates to the next page in navigation history.This is equivalent to GoForward().If the underlying CoreWebView2 is not yet initialized, this method does nothing.

Renders the provided HTML as the top level document of the WebView2.This is equivalent to NavigateToString(String).

Protected focus handler.

Protected OnGotFocus handler.

Overrides the base OnPaint event to have custom actionsin designer mode

Protected SizeChanged handler.

Protected VisibilityChanged handler.

Protected command key handler.

Reloads the top level document of the WebView2.This is equivalent to Reload().

Protected Select method: override this to capture tab direction when WebView control is activated

Stops any in progress navigation in the WebView2.This is equivalent to Stop().If the underlying CoreWebView2 is not yet initialized, this method does nothing.

Overrides the base WndProc events to handle specific window messages.

AcceleratorKeyPressed dispatches when an accelerator key is pressed and before it gets handled by the WebView2.You can write a custom handler to suppress handling by the Webview by doing

.

ContentLoading dispatches after a navigation begins to a new URI and thecontent of that URI begins to render.This is equivalent to the ContentLoading event.

This event is triggered either 1) when the control's CoreWebView2 has finished being initialized (regardless of how it was triggered or whether it succeeded) but before it is used for anythingOR 2) the initialization failed.You should handle this event if you need to perform one time setup operations on the CoreWebView2 which you want to affect all of its usages(e.g. adding event handlers, configuring settings, installing document creation scripts, adding host objects).

NavigationCompleted dispatches after a navigate of the top leveldocument completes rendering either successfully or not.This is equivalent to the NavigationCompleted event.

NavigationStarting dispatches before a new navigate starts for the toplevel document of the WebView2.This is equivalent to the NavigationStarting event.

SourceChanged dispatches after the Source property changes. This may happenduring a navigation or if otherwise the script in the page changes theURI of the document.This is equivalent to the SourceChanged event.

WebMessageReceived dispatches after web content sends a message to theapp host via chrome.webview.postMessage.This is equivalent to the WebMessageReceived event.

ZoomFactorChanged dispatches when the ZoomFactor property changes.This is equivalent to the ZoomFactorChanged event.
