Hi @chen chen

Welcome to Microsoft Q&A!

Refer to @Viorel 's answer in this thread.

You can define a event_token and use it again in NavigationCompleted.

event_token event = wv1().CoreWebView2().NavigationCompleted({this, &MainWindow::Wv1_NavigationCompleted });
wv1().CoreWebView2().NavigationCompleted(event);

You can also define boolean to choose whether this handler is required.

bool m_bIsNeededNavigationCompleted = false;
if (m_bIsNeededNavigationCompleted)
{
     wv1().CoreWebView2().NavigationCompleted({ this, &MainWindow::Wv1_NavigationCompleted });
}
