Hello,
We have a problem with Page.ParseControl method. We pass a whole page as a string argument. This page also contains css styles (declarative). The result, which is a Control object is added to the main form. All controls are AJAXified on the form. Everything looks fine on first load. But if, for example, a button is clicked (no matter where it was declared - on the parent form or in "string") a post (AJAX) post-back is performed. After it the styles are lost.
Have anybody come across such a thing?
Best regards,
Vladimir Kovalenko

I have worked it around by placing internal CSS styles inside <body /> instead of <head /> as usual.
This behavior is observed only in IE. This might be some sort of bug. Anybody knows?

Hello Vladimir,
I am not sure I understood how the CSS styles are related to the whole scenario and how are they used, but I doubt that there is a problem with the AJAX functionality itself. Can you demonstrate a similar approach to the one that you are using on a standalone web page, which exhibits the unexpected behavior?

Hi Dimo,
The problem is reproduced when there is AjaxSettings. Not using AJAX does not cause the problem.
I would post a sample project, but there is no way to attach files here...
Anyway, let's assume there is an HTML page like
and you load this page inside a placeholder. The page is parsed as a string (preliminary read from a file) with the help of Page.ParseControl method. Alongside there is a button next to placeholder. AjaxSettings are set up so that the button updates the placeholder. When you run this form for the first time you will see read background. When you click on the button, it will turn white.
