Creating Custom Controls With Custom Controls Inside Of Them

Hello, I am trying to create a custom control for creating tabs. The idea is that our designer can just use the control tags to generate the tabs.  The problem that I am running into is that I want to be able to have a custom control that allows any number of child custom controls. So there would be a TabContainer Control, and within that there would be any number of tabs.  The idea is similar to how an asp:DropDown list can have any number of ListItems within them.  Here is my code, any help is appreciated.


1    <!-- TAB CONTAINER  -->
2 <%@ Control Language="VB" AutoEventWireup="false" CodeFile="TabContainer.ascx.vb" Inherits="CustomControls_TabContainer" %>
3 <div>
5 <ul class="tabs">
6 <asp:PlaceHolder ID="ph_list_items">
8 </asp:PlaceHolder>
9 </ul>
11 </div>
14 <%@ Control Language="VB" AutoEventWireup="false" CodeFile="Tab.ascx.vb" Inherits="CustomControls_Tab" %>
15 <li>
16 <asp:HyperLink ID="hp_link" runat="server" />
17 </li>
19 <!-- PAGE SOURCE -->
20 <%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>
21 <%@ Register
22 TagPrefix="uc"
23 TagName="TabContainer"
24 src="~\CustomControls\TabContainer.ascx" %>
25 <%@ Register
26 TagPrefix="uc"
27 TagName="Tab"
28 src="~\CustomControls\Tab.ascx" %>

30 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
32 <html xmlns="">
33 <head runat="server">
34 </head>
35 <body>
36 <form id="form1" runat="server">
37 <div>
39 <uc:TabContainer ID="tabs1" runat="server" IncludeArrows="True">
40 <uc:Tab ID="tab1" runat="server" LinkText="Tab1" LinkURL="" />
41 <uc:Tab ID="tab2" runat="server" LinkText="Tab1" LinkURL="" />
42 <uc:Tab ID="tab3" runat="server" LinkText="Tab1" LinkURL="" />
43 </uc:TabContainer>
44 </div>
45 </form>
46 </body>
47 </html>
  For simplicity's sake I have left out the codebehind.

Custom Web Control inside another Custom Web Control
Hi I created a custom web control (CusWebNew) that displays some textboxes by adding them to the ControlCollection of the webcontrol. I also created a custom webcontrol (CustWebButton) that inherts from Button control, and overrided the OnClick function. When I use CustWebButton on a regular web form, it seems to function correctly. However, when I added to be part of the ControlCollection of CustWebNew, it stops to work.   Any ideas why?

Custom User Controls v. Custom Web Controls

Custom Server Control Vs Web Parts, Any need for Custom Server Control
Hello I've just posted a similar question on why you need server controls when you can pre-compile usercontrols and redistribute them. I've seen lots of (usercontrol vs web part) but not much on web part vs custom server control. According to the MSDN site you can put web parts onto a normal page outside of a web part zone and they behave just like custom server controls. So, if you are creating a bunch of controls for redistribution to customer sites and/or SharePoint sites why don't you just create Web Par...

Custom User Controls and dynamically created web controls events not firing
I have a peculiar problem and since I am just starting to use .net I am confident I am doing something wrong, but I can't see it and I've wasted a lot of time so far trying to figure it out. Hopefully one of you can figure it out. I have a custom User Control and I am dynamically creating a RadioButtonList. If I remove the custom user control from the page the RadioButtonList works as expected and correctly. However, once I add the custom control, it does not fire the SelectedIndexChanged event. Below is some code. If all I do is remove: "<UC:TOPMENU id="TopMenu1"...
