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: strOpenHT...

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."

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.

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 ...

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 ...
