An app may call this API to have the WebView2 consume less memory.

ContainsFullScreenElementChanged is raised when the ContainsFullScreenElement property changes.

ContentLoading is raised before any content is loaded, including scripts added with AddScriptToExecuteOnDocumentCreatedAsync(String). ContentLoading is not raised if a same page navigation occurs (such as through fragment navigations or history.pushState navigations).

DocumentTitleChanged is raised when the DocumentTitle property changes and may be raised before or after the NavigationCompleted event.

DOMContentLoaded is raised when the initial HTML document has been parsed.

FrameNavigationCompleted is raised when a child frame has completely loaded (body.onload has been raised) or loading stopped with error.

FrameNavigationStarting is raised when a child frame in the WebView requests permission to navigate to a different URI.

HistoryChanged is raised when there is change of navigation history for the top level document.

NavigationCompleted is raised when the WebView has completely loaded (body.onload has been raised) or loading stopped with error.

NavigationStarting is raised when the WebView main frame is requesting permission to navigate to a different URI.

NewWindowRequested is raised when content inside the WebView requests to open a new window, such as through window.open().

PermissionRequested is raised when content in a WebView requests permission to access some privileged resources.

ProcessFailed is raised when a WebView process ends unexpectedly or becomes unresponsive.

ScriptDialogOpening is raised when a JavaScript dialog (alert, confirm, prompt, or beforeunload) displays for the WebView.

SourceChanged is raised when the Source property changes.

WebMessageReceived is raised when the IsWebMessageEnabled setting is set and the top-level document of the WebView runs window.chrome.webview.postMessage.

WebResourceRequested is raised when the WebView is performing a URL request to a matching URL and resource context filter that was added with AddWebResourceRequestedFilter(String, CoreWebView2WebResourceContext).

WebResourceResponseReceived is raised when the WebView receives the response for a request for a web resource (any URI resolution performed by the WebView; such as HTTP/HTTPS, file and data requests from redirects, navigations, declarations in HTML, implicit favicon lookups, and fetch API usage in the document). The host app can use this event to view the actual request and response for a web resource. There is no guarantee about the order in which the WebView processes the response and the host app's handler runs. The app's handler will not block the WebView from processing the response.

WindowCloseRequested is raised when content inside the WebView requested to close the window, such as after window.close() is run.
