get_IsSuccess

TRUE when the navigation is successful.

public HRESULT get_IsSuccess(BOOL * isSuccess)

FALSE for a navigation that ended up in an error page (failures due to no network, DNS lookup failure, HTTP server responds with 4xx), but may also be FALSE for additional scenarios such as window.stop() run on navigated page. Note that WebView2 will report the navigation as 'unsuccessful' if the load for the navigation did not reach the expected completion for any reason. Such reasons include potentially catastrophic issues such network and certificate issues, but can also be the result of intended actions such as the app canceling a navigation or navigating away before the original navigation completed. Applications should not just rely on this flag, but also consider the reported WebErrorStatus to determine whether the failure is indeed catastrophic in their context. WebErrorStatuses that may indicate a non-catastrophic failure include:

  • COREWEBVIEW2_WEB_ERROR_STATUS_OPERATION_CANCELED

  • COREWEBVIEW2_WEB_ERROR_STATUS_VALID_AUTHENTICATION_CREDENTIALS_REQUIRED

  • COREWEBVIEW2_WEB_ERROR_STATUS_VALID_PROXY_AUTHENTICATION_REQUIRED
