C# webbrowser appel Ajax

Contrôle WebBrowser (WPF et WinForms versions) se comporte de nombreuses façons différemment de la pleine IE. Vous pouvez mettre en œuvre Fonction De Contrôle De La à apporter son comportement en tant que proche de IE que possible (en particulier, FEATURE_BROWSER_EMULATION), cela permet souvent de résoudre le script des problèmes de compatibilité. Voici un peu de code, notez qu'il ne nécessite pas de droits d'admin à exécuter:

private void SetBrowserFeatureControlKey(string feature, string appName, uint value)
{
    using (var key = Registry.CurrentUser.CreateSubKey(
        String.Concat(@"Software\Microsoft\Internet Explorer\Main\FeatureControl\", feature), 
        RegistryKeyPermissionCheck.ReadWriteSubTree))
    {
        key.SetValue(appName, (UInt32)value, RegistryValueKind.DWord);
    }
}

Par exemple:

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_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(@"SOFTWARE\Microsoft\Internet 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:

break;
case 9:

}

Vous devez venir avec votre propre l'ensemble des fonctionnalités de et de les enregistrer avant WebBrowser a initialisé, par exemple, dans le formulaire principal constructeur:

public MainWindow()
{
SetBrowserFeatureControl();
InitializeComponent();
//...
}
