我们在做Sharepoint2007时,习惯于用对项目模型来获取数据,但都是后台代码,和客户端不能很好的互动,感觉很不爽,今天我来迎来了Sharepoint2010,它带来了客户端对象模型,听名字就知道干什么的呢,但今天我们不是讲客户端对象模型,还是另一种方式获取Sharepoint数据源,那就是 OData Service 。
(一) 使用OData Service 的前提得必须要安装一个补丁,叫做“ADO.NET Data Services Update for .NET Framework 3.5 SP1 for Windows 7 and Windows Server 2008 R2” ,安装好后重启,然后打开“http://mySite/_vti_bin/ListData.svc
”,(mySite)是自己的站点,你可以看到自己站点上所有的列表信息,如果你要看某一个列表的数据,则打开这个地址“http://mySite/_vti_bin/ListData.svc/myListName” 。
(二)你要使用AJAX获取OData Service ,则需要安装AJAX控件工具包源代码(我用的是AjaxControlToolkit.Source.zip),然后把其中的几个文件按下面的方法放置:
(三)写代码(用VS2010 创建一个Sharepoint空项目,然后创建一个页面)
<% @ Assembly Name = " $SharePoint.Project.AssemblyFullName$ " %>
<% @ Import Namespace = " Microsoft.SharePoint.ApplicationPages " %>
<% @ Register Tagprefix = " SharePoint " Namespace = " Microsoft.SharePoint.WebControls " Assembly = " Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c " %>
<% @ Register Tagprefix = " Utilities " Namespace = " Microsoft.SharePoint.Utilities " Assembly = " Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c " %>
<% @ Register Tagprefix = " asp " Namespace = " System.Web.UI " Assembly = " System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 " %>
<% @ Import Namespace = " Microsoft.SharePoint " %>
<% @ Assembly Name = " Microsoft.Web.CommandUI, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c " %>
<% @ Page Language = " C# " AutoEventWireup = " true " CodeBehind = " UserStories.aspx.cs " Inherits = " PreDemo.Layouts.PreDemo.UserStories " DynamicMasterPageFile = " ~masterurl/default.master " %>
< asp:Content ID = " PageHead " ContentPlaceHolderID = " PlaceHolderAdditionalPageHead " runat = " server " >
< style type = " text/css " >
.sys - template
{
display:none;
}
< / style>
< script src = " /_layouts/Scripts/MicrosoftAjax/Start.js " type = " text/javascript " >< / script>
< script src = " /_layouts/Scripts/MicrosoftAjax/MicrosoftAjax.js " type = " text/javascript " >< / script>
< script type = " text/javascript " >
Sys.require([
Sys.components.dataView,
Sys.components.openDataServiceProxy,
Sys.scripts.jQuery
]);
Sys.onReady( function () {
var dataSource = Sys.create.openDataServiceProxy( ' /_vti_bin/ListData.svc ' );
Sys.query( " #userStoriesList " ).dataView({
dataProvider: dataSource,
fetchOperation: " Tasks " ,
feachParameters: { orderby: ' 标题 ' },
autoFetch: " true "
});
});
< / script>
< / asp:Content>
< asp:Content ID = " Main " ContentPlaceHolderID = " PlaceHolderMain " runat = " server " >
Hello World !
< ul id = " userStoriesList " class = " sys-template " >
< li > {{ 标题 }} < / li>
< / ul>
< / asp:Content>
< asp:Content ID = " PageTitle " ContentPlaceHolderID = " PlaceHolderPageTitle " runat = " server " >
应用程序页
< / asp:Content>
< asp:Content ID = " PageTitleInTitleArea " ContentPlaceHolderID = " PlaceHolderPageTitleInTitleArea " runat = " server " >
我的应用程序页
< / asp:Content>
Tasks是我的任务列表,<li>{{ 标题 }}</li> 是绑定数据
最后一个要注意的是sys-template类。这是一个在ASP.Net AJAX中预定义的CSS类,当完成渲染工作后,由ASP.Net AJAX将其设置为display:block。因此,我们需要为sys-template创建一个CSS类并设为display:none,这样在页面加载过程中最终用户就看不到你的模板代码了。
(四)最后,你按F5部署到站点上,就可以看见自己的数据了。
下次还要写AJAX如何运用这些数据实现很炫的效果。
