Hi I am trying to add the RadAjaxManager programmatically to a page and override the Render method on the page. Here is my code:

    
            using System;  
        
            using System.Collections;  
        
            using System.Configuration;  
        
            using System.Data;  
        
            using System.Web;  
        
            using System.Web.Security;  
        
            using System.Web.UI;  
        
            using System.Web.UI.HtmlControls;  
        
            using System.Web.UI.WebControls;  
        
            using Telerik.Web.UI;  
        
            namespace Neetrix.Web.Administration.TempFiles  
        
            {  
        
                public partial class TestRender : Page  
        
                {  
        
                    protected void Page_Load(object sender, EventArgs e)  
        
                    {  
        
                        RadAjaxManager AjaxManager = new RadAjaxManager();  
        
                        AjaxManager.ID = "RadAjaxManager1";              
        
                        HtmlForm form = new HtmlForm();  
        
                        form.Controls.Add(new ScriptManager());  
        
                        form.Controls.Add(AjaxManager);  
        
                        form.Controls.Add(new LiteralControl("hello"));  
        
                        this.Page.Controls.Add(form);  
        
                    }  
        
                    protected override void Render(HtmlTextWriter writer)  
        
                    {  
        
                        writer.Write("<html>");  
        
                        base.Render(writer);   
        
                        writer.Write("</html>");  
        
                    }  
        
                }      
        
            }

After compiled and run it, it repeating itself when it reach the line "base.render(writer)". If you view page source on the page, you can clearly see that it duplicate both "<html>" and </html>" tags. If I took out the line "form.Controls.Add(AjaxManager)", it will behave correctly. So my question is, is it a bug or is there something i have missed? Thanks in advanced.
