public class ViewManager<T> where T : System.Web.UI.UserControl
    {
        private System.Web.UI.Page m_pageHolder;

        public T LoadViewControl(string path)
        {
            this.m_pageHolder = new System.Web.UI.Page();

            return (T)this.m_pageHolder.LoadControl(path);
        }

        public string RenderView(T control)
        {
            StringWriter output = new StringWriter();

            this.m_pageHolder.Controls.Add(control);
            HttpContext.Current.Server.Execute(this.m_pageHolder, output, false);

            return output.ToString();
        }
    }

Control control = viewManager.LoadViewControl("~/Controls/" + name);
context.Response.Write(viewManager.RenderView(control));
