Member variable CoreWebView2Settings():IsBuiltInErrorPageEnabled Foundation
Controls whether built-in error pages are displayed.
This member variable determines whether the WebView2 control displays its built-in error pages for navigation failures, network errors, or HTTP error responses. When set to .T. (true), standard error pages are shown. When set to .F. (false), error pages are suppressed, allowing the application to handle errors and display custom error content through navigation event handlers. The built-in error pages are enabled by default.
