body: <p>I've tried to use Ajax Control Tool Kits on SharePoint 2010 Web Site, but Im having some trouble with registration. I've searched a lot on google for a solution. I've found some ways, but my problem is not solved. When I open my web site, still getting registration error.

  <p>The problem is registration of Ajax Tool Kit. Here is my steps.</p>
  
  <p>1 - Downloaded Ajax Control Tool Kit latest version.</p>
  
  <p>2 - Added following line to my page </p>
  
  <pre><code>&lt;%@ Register Assembly="AjaxControlToolkit, Version=3.0.30930.28736, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %&gt;
  </code></pre>
  
  <p>3 - Added following line to my master page (v4.master)</p>
  
  <pre><code>&lt;%@ Register Assembly="AjaxControlToolkit, Version=3.0.30930.28736, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %&gt; 
  </code></pre>
  
  <p>4 - Replaced this tag </p>
  
  <pre><code>&lt;asp:ScriptManager&gt;
  </code></pre>
  
  <p>with</p>
  
  <pre><code>&lt;ajaxToolkit:ToolkitScriptManager&gt;
  </code></pre>
  
  <p>but problem not solved..  Still getting same registration error. I need your suggestions about implementing Ajax Control Tool Kits on Share Point 2010. Thank you.</p>
