That's called a composite control -- "Mark As Answer" if my reply helped you --
What gunteman said, that is one approach and in most cases the right one.But its also possible to add child controls to a Control thats inherit from WebControl itself.
Be sure to implement INamingContainer to that inherited Control too, thats the important point of that approach.--Microsoft MVP - Visual Developer ASP / ASP.NET- http://www.aspnetzone.de/blogs/peterbuch...Controlling web control instances on Web Form
I have created a composite control, extending functionality of the Hidden Control. However, I would like to prevent the user from adding this control to the page multiple times. I only want one instance of the control on the Web Form. What setting in my project to I adjust to enable this functionality? I can not find it in any of the books that I have referenced. Is this a setting or is this code that has to be added to the inheriting class.
Looks like there is no standard apporach. But I'd consider using static field to count number of created objects and throw exception if second object ...After a user has entered his registration info I want to add him to my database.

The Gridview and Formview controls provide good functionality in some circumstances but are clumsey in others. As a newbie to .NET I was wondering if its appropriate to do databinding with textboxes and other data controls outside of one of the new data controls (formview, gridview, etc). Or is it a new standard to always use one of the new data controls. If the answer is yes, would you still use an SQLDatasource, or would you set up the connection in code? And, how would you deal with the syntax? In the Formview we have:
<asp:TextBox ID="fnameTextBox" runat="server" ...Problem in accessing web form data in user controls when create user control dynamically

I am working a solution to enhance slave controls. I have created a proof of concept based on the 2.04 code base that shows how to load slave controls without switching to the admin view. I have included a sample module that contains 3 view controls. Each control has a row of buttons that can be used to load one of the other 2 controls. (and no I am not using panels.) The default control has a drop down of other instances of the dynamic control that exist on the current tab.

Hi,There are two simple web user controls A and B, where B contains A. They just display the bunch of text boxes, so I do not need them even in tool pane. They sit in the same project next to web form.I noticed that web user control put on ASPX page does not appear in code behind, but if I create it with protected keyword and name being exactly the same as id it works fine. I can access such a web control from code behind and see the value assigned in IE. The problem is that the same routine does work for my A web control in B. When I assign the value IE, I keep getting null reference. ...How to access individual controls from a form containing the web user control containing those controls
Below is a block of code in my .aspx form named default.aspx. In this form I load a web user control.

I want to set the properties on those controls, but I am baffled as to how to access the control. For example I have a text label control named "label3". How do I access this control.
Because for example, under certain situations I want to hide that control. ( Label3.Visible = false;)
