title: Stop Master page refreshing while navigating between pages?
body: <p>I'm using Master Page in my ASP.net application, in the master page I put a ContentPlaceHolder in Update Panel to support AJAX in child pages, the question is how to stop Refreshing "master page controls" while navigating between pages?</p>
  
  <p>For navigation between pages I tried to use <em>Response.Redirect</em>, <em>windows.location</em> java script with no success, shall I use the Frames or IFrames instead of Master Pages to stop Refreshing? </p>
  
  <p>any suggestion to solve this issue will be highly appreciated, Thanks in advance...</p>
