为MicrosoftASP.NETAJAX1.0扩展SharePointweb.config
我们需要为Ajax注册一些特定的条目。编辑SharePoint的web.config文件，该文件通常位于如下目录：
c:\inetpub\wwwroot\wss\virtualdirectories\80
添加<sectionGroup>元素到 <configSections>标记：<configSections>
<sectionGroupname="system.web.extensions"type="System.Web.Configuration.SystemWebExtensionsSectionGroup,System.Web.Extensions,Version=1.0.61025.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35">
<sectionGroupname="scripting"type="System.Web.Configuration.ScriptingSectionGroup,System.Web.Extensions,Version=1.0.61025.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35">
<sectionname="scriptResourceHandler"type="System.Web.Configuration.ScriptingScriptResourceHandlerSection,System.Web.Extensions,Version=1.0.61025.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35"requirePermission="false"allowDefinition="MachineToApplication"/>
<sectionGroupname="webServices"type="System.Web.Configuration.ScriptingWebServicesSectionGroup,System.Web.Extensions,Version=1.0.61025.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35">
<sectionname="jsonSerialization"type="System.Web.Configuration.ScriptingJsonSerializationSection,System.Web.Extensions,Version=1.0.61025.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35"requirePermission="false"allowDefinition="Everywhere"/>
<sectionname="profileService"type="System.Web.Configuration.ScriptingProfileServiceSection,System.Web.Extensions,Version=1.0.61025.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35"requirePermission="false"allowDefinition="MachineToApplication"/>
<sectionname="authenticationService"type="System.Web.Configuration.ScriptingAuthenticationServiceSection,System.Web.Extensions,Version=1.0.61025.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35"requirePermission="false"allowDefinition="MachineToApplication"/>
</sectionGroup>
</sectionGroup>
</sectionGroup>
</configSections>
添加<controls>节的内容，放在<system.web>/<pages>标记中。 <pages>
<controls>
<addtagPrefix="asp"namespace="System.Web.UI"assembly="System.Web.Extensions,Version=1.0.61025.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35"/>
</controls>
</pages>
在<compilation>标记内的<assemblies>标记中添加下面的内容： <assemblies>
<addassembly="System.Web.Extensions,Version=1.0.61025.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35"/>
</assemblies>
在<httpHandlers>节中添加下面的内容： <httpHandlers>
<addverb="*"path="*.asmx"validate="false"type="System.Web.Script.Services.ScriptHandlerFactory,System.Web.Extensions,Version=1.0.61025.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35"/>
<addverb="*"path="*_AppService.axd"validate="false"type="System.Web.Script.Services.ScriptHandlerFactory,System.Web.Extensions,Version=1.0.61025.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35"/>
<addverb="GET,HEAD"path="ScriptResource.axd"type="System.Web.Handlers.ScriptResourceHandler,System.Web.Extensions,Version=1.0.61025.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35"validate="false"/>
</httpHandlers>
在HttpModules节中添加下面的注册内容，放在所有已有的注册内容下面 <httpModules>
<addname="ScriptModule"type="System.Web.Handlers.ScriptModule,System.Web.Extensions,Version=1.0.61025.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35"/>
</httpModules>
在<SharePoint>/<SafeControls>节中，添加一条SafeControl，用于MicrosoftAjaxExtensions的System.Web.UI命名空间。 <SafeControls>
<SafeControlAssembly="System.Web.Extensions,Version=1.0.61025.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35"Namespace="System.Web.UI"TypeName="*"Safe="True"/>
</SafeControls>
最后,添加下面的configuration标记到web.config文件末尾,在结束标记<configuration>前面。
<system.web.extensions>
<scripting>
<webServices>
<!--Uncommentthislinetoenabletheauthenticationservice.IncluderequireSSL="true"ifappropriate.-->
<!--
<authenticationServiceenabled="true"requireSSL="true|false"/>

利用AjaxBaseWebPart进行开发编写使用该扩展的WebPart最简单的办法就是直接继承别人写好的AjaxBaseWebPart。下面是我用的一个。您也可以用其他的，或自己写一个。

usingSystem.Xml.Serialization;
usingSystem.Web.UI;
usingMicrosoft.SharePoint.WebPartPages;
usingMicrosoft.SharePoint.Utilities;
usingSystem.Web.UI.WebControls;
usingSystem.Drawing;
下面是AjaxBaseWebPart类的实现部分：

开发时只要继承这个WebPart就可以添加UpdatePanel，并在里面添加其他控件了。
