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."
Hi,
As far as I know, we have no luck to control the load order of the Web controls on a page. However, if we need to load some controls under given conditions, we can achieve this by adding them dynamically instead.Forwa...
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 ;)
Some code please.-- Justin Lovell...

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 ...
Getting the Selected Item of dropdownlist inside Web User Control on a Web Form
Ive got a dropdownlist control inside a web user control called Entity.ascx. This web user control is on a webform.aspx. In Entity.ascx class I created a SelectedEntity property that returns the selected item in the dropdownlist.

Web control in web control
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. ...

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 ...

Can my web page with a form submit to other web pages forms?
I was wondering if I created an aspx page that had a form on it that I could use the submit button to submit this form's contents to other web pages forms(servers accepting those form's data). I am thinking this would be a great way to update data on particular web pages without having to actually visit those similar web pages. Any ideas, examples would be much appreciated. Thanks in advance.
