not have a portion of the web page display on a page reload

Question

In an existing web form 2010  .net application the entire page gets reloaded whenever a button or a link is clicked on. When this occurs the bottom portion of the entire lower half of the web page is displayed for a few second and then goes away. The item goes away (is not visible) when the javascript hide function is called. Is there away to keep the lower part of the web form page from being displayed when the entire page is reloaded? If so what would that code be? If not is there some other call  like in ajax that will only show a portion of the web page when it is refreshed (reloaded)? Would you tell me what you recommend?

In your case you have to use update panel and have those button and links inside the update panel. So that the entire page will not reloads and the contents within the panel will be refreshed asynchronously.The reason for footer section of the page displayed and hidden later is the javascript hide method should have been called in document.Ready function.
