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

David Johnson

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);

    }
