SharePoint应用AJAX.NET和AJAX Control Toolkit

1. 首先，在SharePoint服务器上安装ASP.NET 2.0 AJAX Extensions.

2. 修改SP站点web.config,在c:\inetpub\wwwroot\wss\virtualdirectories\下会有对应站点占用端口号的文件夹，web.config就在这里:
  1)  在<configSections>下添加

<sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
      <sectionGroup name="scripting" type="System.Web.Configuration.ScriptingSectionGroup, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
        <section name="scriptResourceHandler" type="System.Web.Configuration.ScriptingScriptResourceHandlerSection, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" allowDefinition="MachineToApplication" />
        <sectionGroup name="webServices" type="System.Web.Configuration.ScriptingWebServicesSectionGroup, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
          <section name="jsonSerialization" type="System.Web.Configuration.ScriptingJsonSerializationSection, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" allowDefinition="Everywhere" />
          <section name="profileService" type="System.Web.Configuration.ScriptingProfileServiceSection, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" allowDefinition="MachineToApplication" />
          <section name="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>

    2) <SafeControls>下添加：

< SafeControl  Assembly ="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"  Namespace ="System.Web.UI"  TypeName ="*"  Safe ="True"   />

  3)  在 <httpHandlers>下添加：

<add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
      <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
      <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false" />

  4)  在<httpModules>下添加：

< add  name ="ScriptModule"  type ="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"   />

  5) 在<assemblies>下添加：

< add  assembly ="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"   />

  6) 在<pages>下添加：

< controls >
         < add  tagPrefix ="asp"  namespace ="System.Web.UI"  assembly ="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"   />
       </ controls >

 7) 在<configuration>下的最后添加：

< system .web.extensions >
     < scripting >
       < webServices >
         <!--  Uncomment this line to enable the authentication service. Include requireSSL="true" if appropriate.  -->
         <!--
        <authenticationService enabled="true" requireSSL = "true|false"/>
       -->
         <!--  Uncomment these lines to enable the profile service. To allow profile properties to be retrieved and modified in ASP.NET AJAX applications, you need to add each property name to the readAccessProperties and writeAccessProperties attributes.  -->
         <!--
      <profileService enabled="true"
                      readAccessProperties="propertyname1,propertyname2"
                      writeAccessProperties="propertyname1,propertyname2" />
       -->
       </ webServices >
       <!--
      <scriptResourceHandler enableCompression="true" enableCaching="true" />
       -->
     </ scripting >
   </ system.web.extensions >
   < system .webServer >
     < validation  validateIntegratedModeConfiguration ="false"   />
     < modules >
       < add  name ="ScriptModule"  preCondition ="integratedMode"  type ="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"   />
     </ modules >
     < handlers >
       < remove  name ="WebServiceHandlerFactory-Integrated"   />
       < add  name ="ScriptHandlerFactory"  verb ="*"  path ="*.asmx"  preCondition ="integratedMode"  type ="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"   />
       < add  name ="ScriptHandlerFactoryAppServices"  verb ="*"  path ="*_AppService.axd"  preCondition ="integratedMode"  type ="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"   />
       < add  name ="ScriptResource"  preCondition ="integratedMode"  verb ="GET,HEAD"  path ="ScriptResource.axd"  type ="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"   />
     </ handlers >
   </ system.webServer >

3. 在webpart中就使用ScriptManager和UpdatePanel
  1)  添加 System.Web.Extensions引用
  2)  添加代码如下：

 protected override void OnInit(EventArgs e)
        {
            base.OnInit(e);
            ScriptManager SM = ScriptManager.GetCurrent(this.Page);

            if (SM == null)
            {
                SM = new ScriptManager();
                SM.ID = "SM";

                if (this.Page.IsPostBack)
                {
                    Page.ClientScript.RegisterStartupScript(
                        typeof(AJAXWebPart),
                        this.ID,
                        "_spOriginalFormAction = document.forms[0].action; _spSuppressFormOnSubmitWrapper=true;",
                        true);
                }

                if (this.Page.Form != null)
                {
                    string formOnSubmitAtt = this.Page.Form.Attributes["onsubmit"];
                    if (!string.IsNullOrEmpty(formOnSubmitAtt) && formOnSubmitAtt ==
                    "return _spFormOnSubmitWrapper();")
                    {
                        this.Page.Form.Attributes["onsubmit"] = "_spFormOnSubmitWrapper();";
                    }
                    this.Page.Form.Controls.AddAt(0, SM);
                }
            }
        }

此代码来自十一。

  3)  在CreateChildControls()方法里添加UpdatePanel：

            UpdatePanel up  =   new  UpdatePanel();
            up.ID  =   " UpdatePanel2 " ;
            up.ChildrenAsTriggers  =   true ;
            up.UpdateMode  =  UpdatePanelUpdateMode.Always;
             this .Controls.Add(up);

            Button button  =   new  Button();
            button.Text  =   " Groups " ;
            button.Click  +=   new  EventHandler(HandleButtonClick);
            up.ContentTemplateContainer.Controls.Add(button);

            listbox1  =   new  ListBox();
            listbox2  =   new  ListBox();
            up.ContentTemplateContainer.Controls.Add(listbox1);
            up.ContentTemplateContainer.Controls.Add(listbox2);

Button事件：

         private   void  HandleButtonClick( object  sender, EventArgs eventArgs)
         {
            SPWeb currentWeb = SPContext.Current.Web;
            foreach (SPGroup group in currentWeb.CurrentUser.Groups)
            {
                listbox1.Items.Add(group.Name);
            }
            foreach (SPGroup group in currentWeb.CurrentUser.OwnedGroups)
            {
                listbox2.Items.Add(group.Name);
            }
        }

这样，我们的webpart在updatepanel的帮助下实现AJAX效果！


再让我们的WSS站点支持AJAX Control Toolkit。

1. 将AjaxControlToolkit.dll添加到GAC.
将AjaxControlToolkit.dll拖拽到C:\Windows\Assembly下就可以了.

2. 继续修改WSS站点web.config
 在<assemblies>下添加：

< add  assembly ="AjaxControlToolkit, Version=1.0.10618.0, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e"   />

 在<controls>下添加：

< add  tagPrefix ="ajaxToolkit"  namespace ="AjaxControlToolkit"  assembly ="AjaxControlToolkit, Version=1.0.10618.0, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e"   />

这样，在WebPart中就可以使用Toolkit里面的控件了。

添加AjaxControlToolkit引用；

在上面代码基础上添加代码：

this .textBox  =   new  TextBox();
             this .textBox.ID  =   " TextBox " ;
            up.ContentTemplateContainer.Controls.Add( this .textBox);
            c  =   new  AjaxControlToolkit.CalendarExtender();
            c.TargetControlID  =   " TextBox " ;
            up.ContentTemplateContainer.Controls.Add(c);

我们也可以在webpart中加载包含Toolkit 控件的UC。

            Control ctl  =  Page.LoadControl( " ~\\wpresources\\MyJAJXCalendar.ascx " );
            Controls.Add(ctl);

当然，UC也可以用Feature去加载到页面上。
效果如下：
