OK I'm an Idiot.. Can not load a control

Question

On the test page.. @ Page Title ="" Language ="C#" MasterPageFile ="~/MasterPages/Site.master" AutoEventWireup ="true" CodeFile ="Default2.aspx.cs" Inherits ="Default2" %> @ MasterType VirtualPath ="~/MasterPages/Site.master"/> @ Register src ="Controls/CartControl.ascx" tagname ="CartControl" tagprefix ="uc1" %> asp : Content ID ="Content1" ContentPlaceHolderID ="PlaceStyleSheetsHere" Runat ="Server"> asp : Content > asp : Content ID ="Content2" ContentPlaceHolderID ="PlaceContentHere" Runat ="Server"> uc1 : CartControl ID ="crap" runat ="server" /> asp : Content > WORKS LIKE A CHARM.. BUT using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class Default2 : SiteBasePage { protected void Page_Load( object sender, EventArgs e) { Controls_CartControl ctrl = new Controls_CartControl (); Controls.Add(ctrl); } } DOES NOT WORK AT ALL... What the heck is wrong with this????

The Code behind looks like this public partial class Cart : SiteBasePage { protected void Page_Load( object sender, EventArgs e) { CartControl control = new CartControl (); control.ID = "OrderItem1" ; control.Visible = true ; CartControlsDiv.Controls.Add(control); } } the Page Code looks like this div id ="CartControlsDiv" runat ="server"> uc1 : CartControl ID ="crap" runat ="server" /> div > Crap renders but the OrderItem1 does not Also what is the diff in a user control and a webControl??? Finally the weirdes thing is on unload of the control all the controls on the page are still NULL I have a test textbox called textbox1 and when I try to set the text the Textbox1 is a property of the control but it is null???? Do I have to manually fire Create Child Controls????

Add it to something like a panel or div with by it's id and with runat="server" set. For example, if you want to add it to a div set up like this: form id ="form1" runat ="server"> div id ="SomeDiv" runat ="server"> div > form > You would use this code: protected void Page_Load( object sender, EventArgs e) { TextBox tb = new TextBox (); tb.ID = "txt1" ; tb.Text = "Look at that" ; SomeDiv.Controls.Add(tb); }
