title: Multiple update Panel in Form
body: <p>I am new Asp.net and working on project, where I have to ajaxify the basic asp.net </p>
  
  <p>I have master page and content page. Master page has menu and buttons. The content page have various fieldsets as below.</p>
  
  <ol>
  <li>Update Record Fieldset</li>
  <li>Add  Record Fieldset</li>
  <li>Query and Grid.</li>
  </ol>
  
  <p>updatepanel id=UpdatePanelOuter runat=server UpdateMode=Conditional> Likewise for all the nested UpdatePanels. The Scriptmanager is in Masterpage with EnablePartialRendering=true </p>
  
  <p>What I have in code behind is ScriptManager1.RegisterAsyncPostBackControl(AddUpdatePanel) In button click event function AddUpdatePanel.Update() .</p>
  
  <p>When the content page is loaded, I have the queryform and DataGrid. There are couple grid command like view, update and delete.</p>
  
  <p>When I click update command from the grid, I am making <code>UpdateFieldset.visible=true</code>  and <code>QueryGridField.visible=false</code>.</p>
  
  <p>On submit button, its stored the data , give the message and go back to original contentpage with <code>querygridFieldset.visible =true</code>.</p>
  
  <p>Question: What I am trying and have not been successfull is</p>
  
  <ol>
  <li>when I click on the buttons, my datetime , menus in the master page
  must not  be refreshed.</li>
  <li>On click in the Update button, only that particular Fieldset should
  be sent to the server.</li>
  </ol>
  
  <p>At the same time, I have updated by Web.config and there is no compilation error </p>
