I am using a webbrowser control embeded in C# WPF .NET4 app. Whenever I press manually the button in a form, the browser hangs on "Your request is being processed" message and nothing happens. If I do the same in full IE browser the page is processed normally producing the results.
What I am missing? Thanks
The code behind the button is the following



<a onclick="startSearch();" href="javascript:void(-1);" name="btnNext" class="btn floatLe noClear btnSubmit btnRight"> 
<span>Continue</span>
</a>

          WebBrowser control (both WPF and WinForms versions) behaves in many ways differently from the full IE. You may want to implement Feature Control to bring its behavior as close to IE as possible (particularly, FEATURE_BROWSER_EMULATION), this often solves the script compatibility issues. Here is some code, note that it does not require admin rights to run:



          private void SetBrowserFeatureControlKey(string feature, string appName, uint value)
          {
          using (var key = Registry.CurrentUser.CreateSubKey(
          String.Concat(@"SoftwareMicrosoftInternet ExplorerMainFeatureControl", feature),
          RegistryKeyPermissionCheck.ReadWriteSubTree))
          {
          key.SetValue(appName, (UInt32)value, RegistryValueKind.DWord);
          }
          }


          For example:



          private void SetBrowserFeatureControl()
          {
          // http://msdn.microsoft.com/en-us/library/ee330720(v=vs.85).aspx

          // FeatureControl settings are per-process
          var fileName = System.IO.Path.GetFileName(Process.GetCurrentProcess().MainModule.FileName);

          // make the control is not running inside Visual Studio Designer
          if (String.Compare(fileName, "devenv.exe", true) == 0 || String.Compare(fileName, "XDesProc.exe", true) == 0)
          return;

          SetBrowserFeatureControlKey("FEATURE_BROWSER_EMULATION", fileName, GetBrowserEmulationMode()); // Webpages containing standards-based !DOCTYPE directives are displayed in IE10 Standards mode.
          SetBrowserFeatureControlKey("FEATURE_AJAX_CONNECTIONEVENTS", fileName, 1);
          SetBrowserFeatureControlKey("FEATURE_ENABLE_CLIPCHILDREN_OPTIMIZATION", fileName, 1);
          SetBrowserFeatureControlKey("FEATURE_MANAGE_SCRIPT_CIRCULAR_REFS", fileName, 1);
          SetBrowserFeatureControlKey("FEATURE_DOMSTORAGE ", fileName, 1);
          SetBrowserFeatureControlKey("FEATURE_GPU_RENDERING ", fileName, 1);
          SetBrowserFeatureControlKey("FEATURE_IVIEWOBJECTDRAW_DMLT9_WITH_GDI ", fileName, 0);
          SetBrowserFeatureControlKey("FEATURE_DISABLE_LEGACY_COMPRESSION", fileName, 1);
          SetBrowserFeatureControlKey("FEATURE_LOCALMACHINE_LOCKDOWN", fileName, 0);
          SetBrowserFeatureControlKey("FEATURE_BLOCK_LMZ_OBJECT", fileName, 0);
          SetBrowserFeatureControlKey("FEATURE_BLOCK_LMZ_SCRIPT", fileName, 0);
          SetBrowserFeatureControlKey("FEATURE_DISABLE_NAVIGATION_SOUNDS", fileName, 1);
          SetBrowserFeatureControlKey("FEATURE_SCRIPTURL_MITIGATION", fileName, 1);
          SetBrowserFeatureControlKey("FEATURE_SPELLCHECKING", fileName, 0);
          SetBrowserFeatureControlKey("FEATURE_STATUS_BAR_THROTTLING", fileName, 1);
          SetBrowserFeatureControlKey("FEATURE_TABBED_BROWSING", fileName, 1);
          SetBrowserFeatureControlKey("FEATURE_VALIDATE_NAVIGATE_URL", fileName, 1);
          SetBrowserFeatureControlKey("FEATURE_WEBOC_DOCUMENT_ZOOM", fileName, 1);
          SetBrowserFeatureControlKey("FEATURE_WEBOC_POPUPMANAGEMENT", fileName, 0);
          SetBrowserFeatureControlKey("FEATURE_WEBOC_MOVESIZECHILD", fileName, 1);
          SetBrowserFeatureControlKey("FEATURE_ADDON_MANAGEMENT", fileName, 0);
          SetBrowserFeatureControlKey("FEATURE_WEBSOCKET", fileName, 1);
          SetBrowserFeatureControlKey("FEATURE_WINDOW_RESTRICTIONS ", fileName, 0);
          SetBrowserFeatureControlKey("FEATURE_XMLHTTP", fileName, 1);
          }

          private UInt32 GetBrowserEmulationMode()
          {
          int browserVersion = 7;
          using (var ieKey = Registry.LocalMachine.OpenSubKey(@"SOFTWAREMicrosoftInternet Explorer",
          RegistryKeyPermissionCheck.ReadSubTree,
          System.Security.AccessControl.RegistryRights.QueryValues))
          {
          var version = ieKey.GetValue("svcVersion");
          if (null == version)
          {
          version = ieKey.GetValue("Version");
          if (null == version)
          throw new ApplicationException("Microsoft Internet Explorer is required!");
          }
          int.TryParse(version.ToString().Split('.')[0], out browserVersion);
          }

          UInt32 mode = 11000; // Internet Explorer 11. Webpages containing standards-based !DOCTYPE directives are displayed in IE11 Standards mode. Default value for Internet Explorer 11.
          switch (browserVersion)
          {
          case 7:
          mode = 7000; // Webpages containing standards-based !DOCTYPE directives are displayed in IE7 Standards mode. Default value for applications hosting the WebBrowser Control.
          break;
          case 8:
          mode = 8000; // Webpages containing standards-based !DOCTYPE directives are displayed in IE8 mode. Default value for Internet Explorer 8
          break;
          case 9:
          mode = 9000; // Internet Explorer 9. Webpages containing standards-based !DOCTYPE directives are displayed in IE9 mode. Default value for Internet Explorer 9.
          break;
          case 10:
          mode = 10000; // Internet Explorer 10. Webpages containing standards-based !DOCTYPE directives are displayed in IE10 mode. Default value for Internet Explorer 10.
          break;
          default:
          // use IE11 mode by default
          break;
          }

          return mode;
          }


          You should come up with your own set of features and register them before WebBrowser has initialized, e.g., in the main form constructor:



          public MainWindow()
          {
          SetBrowserFeatureControl();

          InitializeComponent();
          //...
          }


          Updated, I currently use and recommend a set of features that can be found here.

            Hmm, hard to tell what's causing it, but I'd again go through the list of all available options and play with those which look related, trying both 1 and 0 values. E.g., FEATURE_AJAX_CONNECTIONEVENTS, FEATURE_WEBOC_POPUPMANAGEMENT, FEATURE_WINDOW_RESTRICTIONS, FEATURE_TABBED_BROWSING etc. Let us know if you find it :)

            You should come up with your own set of features and register them before WebBrowser has initialized, e.g., in the main form constructor:



            public MainWindow()
            {
            SetBrowserFeatureControl();

            InitializeComponent();

E.g., FEATURE_AJAX_CONNECTIONEVENTS, FEATURE_WEBOC_POPUPMANAGEMENT, FEATURE_WINDOW_RESTRICTIONS, FEATURE_TABBED_BROWSING etc. Let us know if you find it :)

            WebBrowser control (both WPF and WinForms versions) behaves in many ways differently from the full IE. You may want to implement Feature Control to bring its behavior as close to IE as possible (particularly, FEATURE_BROWSER_EMULATION), this often solves the script compatibility issues. Here is some code, note that it does not require admin rights to run:



            private void SetBrowserFeatureControlKey(string feature, string appName, uint value)
            {
            using (var key = Registry.CurrentUser.CreateSubKey(
            String.Concat(@"SoftwareMicrosoftInternet ExplorerMainFeatureControl", feature),
            RegistryKeyPermissionCheck.ReadWriteSubTree))
            {
            key.SetValue(appName, (UInt32)value, RegistryValueKind.DWord);
            }
            }


            For example:



            private void SetBrowserFeatureControl()
            {
            // http://msdn.microsoft.com/en-us/library/ee330720(v=vs.85).aspx

            // FeatureControl settings are per-process
            var fileName = System.IO.Path.GetFileName(Process.GetCurrentProcess().MainModule.FileName);

            // make the control is not running inside Visual Studio Designer
            if (String.Compare(fileName, "devenv.exe", true) == 0 || String.Compare(fileName, "XDesProc.exe", true) == 0)
            return;

            SetBrowserFeatureControlKey("FEATURE_BROWSER_EMULATION", fileName, GetBrowserEmulationMode()); // Webpages containing standards-based !DOCTYPE directives are displayed in IE10 Standards mode.
            SetBrowserFeatureControlKey("FEATURE_AJAX_CONNECTIONEVENTS", fileName, 1);

              @Noseratio: Great code. Thank you. FYI: SetBrowserFeatureControlKey("FEATURE_NINPUT_LEGACYMODE", fileName, 0) blocks setting mouse cursor by mouse-clicking inside WebBrowser control navigated web pages' text boxes. Windows 8. IE10.0.9200.16750, update: 10.0.12

            @Jim, I've added a check for "XDesProc.exe" (VS XAML Designer process), you may want to update your code too.

            Hmm, hard to tell what's causing it, but I'd again go through the list of all available options and play with those which look related, trying both 1 and 0 values. E.g., FEATURE_AJAX_CONNECTIONEVENTS, FEATURE_WEBOC_POPUPMANAGEMENT, FEATURE_WINDOW_RESTRICTIONS, FEATURE_TABBED_BROWSING etc. Let us know if you find it :)
