Dynamically adding listbox controls in a web based user control
I am building a web control and trying to dynamically add checkboxs.
I try to create the controls on the render event and i've tried these 3 methods- none of which work.
This method compiles but the checkbox is not visible on the page. I am unsure as to where it is adding to because I can't reference the parents web page.
/*CheckBox blah = new CheckBox();
blah.Text = CheckText;
blah.ID = CheckValue;
This one compiles but the controls also do not display on the page (I knew this wouldn't work but it was worth a try)

Ok, thinking caps on people, this has been causing me grief for a couple of days now.
I have an .aspx page which contains various user controls housed in
an Accordion control from the Ajax Toolkit and lots of UpdatePanels,
these user controls all interact with each other through the parent
page, e.g clicking buttons in one control effects visibility of other
Two of these controls contain just a series of ImageButtons. In the
first of these controls the ImageButtons are generated in the page_load
method and added to a panel using

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. ...Adding web controls to a webpage dynamically using VB.net

I have created a web control in vb.net that has an image button and an image. when it loads the image button is visible and the image is not.
I want to be able from the page which "includes" the web control to set the image button to invisible and the image to visible.
When I tried this, the main page didn't recognise the image button or the image (both < asp: objects).
help would be gratefully appreciated.
oh yeah, it's inline code so any code behind stuff will just confuse me ;)

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.

I want to add .NET Control (like: TextBox, Button...) to Web Custom Control.How i can do it? Alphavn
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...Dynamic Control problem in Web user control

So the question is whether or not it is possible to add controls dynamically to your custom control at runtime and if it is how?
I'm working on building a custom that makes use of custom paging without datagrids or other controls with such built in functionality and I'd like to be able to use the ASP HyperLink control for navigating the pages instead of just outputing simple HTML anchors which change the query string in http response headers.
Any assitance appreciated.CheersChallenge Limits!

I have a page where the user gets to add controls to the page, controls like a forum or a blog or something like that,
these are usercontrols that the user adds, and the masterpage loops through the controls in order and adds them like this:
TopControlIndex += 1
then the user can move the controls up or down by changing the index field in the db, so that the forum gets moved up over the blog and so on and so forth.
now this only works for the dynamically added controls,
