There is Redirect column which disables a user to enter the web site page. Once I filled out the redirect dauerhaft, the color of the icon of Digitales Postfach should change.

So as seen below, contentType.Icon is set to blue. even it is not what I am targeting, because I need to change the parent icon.

Is it possible to do it?

  public void ReIndexContent(IContent content, string eventArgsSource = null)
    {
        content.ContentType.Icon = "icon-application-window-alt color-blue";
    }
