To get rid of the script errors, you'll need to fix the script on your page. You can't do that from WPF.

Remember, the WebBrowser control is stuck in IE7 mode unless you modify the registry[^] on every machine that runs your application. If your site has errors in IE7, then it will have errors in the WebBrowser control.

If you just want to stop the errors from displaying, try setting the ScriptErrorsSuppressed property[^] to True.

Try this in the Browser_LoadCompleted

C#

private static void MainBrowser_LoadCompleted(object sender, NavigationEventArgs e)
        {
            var wbMain = sender as WebBrowser;

            SetSilent(wbMain, true); // make it silent
        }

private static void SetSilent(WebBrowser browser, bool silent)
        {
            if (browser == null)
                throw new ArgumentNullException("browser");

            // get an IWebBrowser2 from the document
            IOleServiceProvider sp = browser.Document as IOleServiceProvider;
            if (sp != null)
            {
                Guid IID_IWebBrowserApp = new Guid("0002DF05-0000-0000-C000-000000000046");
                Guid IID_IWebBrowser2 = new Guid("D30C1661-CDAF-11d0-8A3E-00C04FC9E26E");

                object webBrowser;
                sp.QueryService(ref IID_IWebBrowserApp, ref IID_IWebBrowser2, out webBrowser);
                if (webBrowser != null)
                {
                    webBrowser.GetType().InvokeMember("Silent", BindingFlags.Instance | BindingFlags.Public | BindingFlags.PutDispProperty, null, webBrowser, new object[] { silent });
                }
            }
        }        
        [ComImport, Guid("6D5140C1-7436-11CE-8034-00AA006009FA"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
        private interface IOleServiceProvider
        {
            [PreserveSig]
            int QueryService([In] ref Guid guidService, [In] ref Guid riid, [MarshalAs(UnmanagedType.IDispatch)] out object ppvObject);
        }
