named NewsForm. This user control contains some web form elements like
<asp:textbox>. When I add it in an .ASPX page, all things may be

Hi, I have 2 User controls on a page and want Control1 to call a method of Control2. Is this Possible?
Con1 = Datalist showing products, each with a Quantity Box and a Button.
Con2 = Repeater showing Cart Preview (name, Price)
When I click on the button on the DataList in Con1 it adds the item into the Session based Cart. However it does not update the Cart Preview. I need to call BindPreview() in Con2 in order to update the Cart Preview...
Does that make sense? argh! any help much appreciated!

Below is a block of code in my .aspx form named default.aspx. In this form I load a web user control. I then add it to a place holder control.(Lines 3 and 4 below) So how do I access the individual controls in my 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;)

Have created a user control for displaying and editing a dynamically number of values. The user control contains two labels and an edit box. When dynamically loading the user control I get an error when the control itself tries to change setting on the fields within the user control.
Why doesnt this work? It works okay if I dont load it dynamically but create a user-control-instance in the aspx-page but thats no solution.
Here is my code:

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 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...Add web control to different user control
A little new to this .NET stuff, so go easy.
I need to dynamically add some web controls into a place holder in a differnt user control than I am in? Any ideas?
I've tried Declaring the placeholder as public, but still cannot reference it from a different user control.
I am OK with the actual dynamic web control bit, it's just the refferencing of the placeholder that I'm struggling with

the web control event should be handle in the code behind page, is the event handler for the button you are clicking registered? You can try double clicking the button, should give you the default btn_click event handler in code behind.

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.
