Implementing Ajax Tool Kit with SharePoint 2010

Implementing Ajax Tool Kit

• I used Ajax 3.0.30930.28736 dll for this project. Because as we know SharePoint 2010 working in .Net 3.5 Framework. Ajax dll 3.5 or more than that used .Net 4.0 framework.
• Custom Master Page contains Ajax Tool kit reference. 
• When feature activated custom master page applied to your SharePoint site.
• Use Visual Web Part contains  
• Ajax Tab 
• ValidatorCallout Control
• Following Ajax reference already added to the Master page.
• First register the Ajax Control Toolkit namespace in the masterpage file by putting the following line at the top of the file:

<%@ Register Assembly="AjaxControlToolkit, Version=3.0.30930.28736,
 Culture=neutral, PublicKeyToken=28f01b0e84b6d53e"
Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %>

• Then remove the ScriptManager registration from the master page by removing the following line:

<asp:ScriptManager id="ScriptManager" runat="server" EnablePageMethods="false"
EnablePartialRendering="true" EnableScriptGlobalization="false" EnableScriptLocalization="true"/>

• Finally add the following line in place of the above line to register Ajax Control Toolkit

<ajaxToolkit:ToolkitScriptManager id="ScriptManager" runat="server" EnablePageMethods="false"
EnablePartialRendering="true" EnableScriptGlobalization="false" EnableScriptLocalization="true"/>

you can use try rest of other Ajax Tool kit controls.
