Single page with multiple user web controls VS Multiple page with specific user web controls
I have a question regarding single page with multiple user web controls vs multiple page with specific user web controls
Option 1: I am of the opinion to have multiple pages with specific user web controls and use an object to store all the information as the user navigates through the application. And finally at the end, read this object and save all the information to the backend database.
Option 2: My respected team member suggests that we have only one page, with all the specific user web controls and not use an object, instead show/hide the user web controls based ...

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 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.

Web User Control to Web User Control...
Hi, I have 2 User controls on a page and want Control1 to call a method of Control2. Is this Possible?
Example:
Con1 = Datalist showing products, each with a Quantity Box and a Button.
Con2 = Repeater showing Cart Preview (name, Price)
in page.aspx.
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!

Can you return .net web controls in a .net page from a web service?
I've got a problem with a project. I've got to compile an entire .net page and return it as part of a Web Service for display. The problem I have is that I need to add WebControls and functionality to the page so that not only the html content and images are displayed (which I've managed) but that textboxes, labels, buttons and datasets can be displayed also. Essentially I need to make a call from one site for a page, populate the page and return it in a state as though it resided on the same server/webspace as the calling page. Code is currently built as follows into a string:

How can I control load sequence of web controls in a web page?
Hi,
How can I control load sequence of web controls in a web page?
Thanks.
For the most part, the load sequence on a web page is not relevant since all controls must be present before the page can be used.
Could you provide more information as to what you're trying to do?Christopher Reed"The oxen are slow, but the earth is patient."

controlling an object in a web control from the page the web control is placed in
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 ;)
