Deploying ASP.NET app with rad controls on a remote Service Provider
Hi,

I am new to ASP.NET and the rad controls.
I have developed a sample application using the trial version of the rad controls and I am trying to publish it on to our website that is hosted by a 3rd party service provider.

While I am able to run the app in my development environment, the application does not run once published to the remote server.

I am using the Copy website option in VS2005 to do this.

Is there a doc that will tell me the steps I should go through while doing such deployment.

Thanks,
Sri

Don't forget about us MOSS users!
It would be great to have a training module for how to integrate the MOSS editor and to point to key resources for getting it up and running and customizing.

Thank You,

CSS references inside <head>

Hi all,

What is the best way to add CSS file references between the <head> tags?

The original way is like this:

<link type="text/css" rel="stylesheet" href="../Assets/Css/all.css" media="screen" />  
<link type="text/css" rel="stylesheet" href="../Assets/Css/Menu.Multiflexx.css" media="screen" />  
<link type="text/css" rel="stylesheet" href="../Assets/Css/Menu.MultiflexxSide.css" media="screen" />  
 
<script type="text/javascript" src="../Assets/Js/script.js"></script>  
<script type="text/javascript" src="../Assets/Js/vscrollarea.js"></script>  
 
<!--[if lte IE 6]><link type="text/css" rel="stylesheet" href="../Assets/Css/ie6.css" /><![endif]-->  
<!--[if IE]><link type="text/css" rel="stylesheet" href="../Assets/Css/ie.css" /><![endif]--> 

When I use this on pages that are 1 or 2 levels deep (in the menu structure) then some styles are not applied. Well, the IE 6 hacks in particular. I tried all kind of things to resolve the right path for the files, but none of them are working.

If anyone has some more ideas to solve this right, let me know.
The problem is that it is important that the order of the files is the same, and that the Conditional comments are also beeing used.

Hi, Sometime I am getting following error while I changed the dropdown index(autopostback=true)..

 Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
