Problems while hosting

I uploaded all files into host. While i'm accessing aspx files from website, it is displaying only html content but no server controls,etc....

When I Used View source on Browser displaying server controls code as it is. what is the problem?

I'm using visual studio 2003. Before uploading i used rebuild option and created dll as well.

Thanks

1. Does your host support ASP.NET? Not all of them do.
2. If so, is your directory configured as an application?

Most hosting companies provide a control panel of some kind to check this. If you don't know, you'll have to contact their support.
