Do you need open a dialogue for a file which is located on client or server? — IvanH

Perhaps you should tell us more about what you are trying to achieve. Any call to common dialogues from the server side will be (try to be) performed on the server. To provide the user with the facility to eq. choose and upload file, you need to use other methods that will be invoked on client side (JScript, Flash, Silverlight...).
