You’ll need to edit your web.config

<add assembly="AjaxControlToolkit, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e"/>

Goes between

<assemblies></assemblies>

tag.

<add tagPrefix="ajaxToolkit" namespace="AjaxControlToolkit" assembly="AjaxControlToolkit, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e"/>

Goes between

 <controls></controls> 

tag.
