I have problem with Composite Control in ASP.NET. Im making a classlibrary with this content \/ , but the problem is, that i cannot see it in toolbox, but i register it in web.config file, compile it and add a reference to it. And another problem is that my composite control cannot raise an event. 


<pre>// composite control

    public class CreateArticleEventArgs : EventArgs
    {
        public bool IsValid { get; private set; }

        {

            this.article = article;
