ASP.NET MVC Preview 5 演示Demo #5 实现MikePager数据分页和GridView控件
上一篇： ASP.NET Mvc Preview 5 演示Demo #4 实现RadioButtonList与DropDownList应用这个演示项目实现了在ASP.NET MVC中使用自定义的Html.GridView()控件和Html.MikePager()数据分页控件。【ok】 开发环境：Visual Studio 2008 SP1 ＋ ASP.NET MVC Preview 5 ＋ Linq To Sql ＋ SQL Server 2005 ASP.NET MVC Preview 5 下载地址： http://www.codeplex.com/aspnet/R ... spx?ReleaseId=16775【Step By Step 操作步骤】 1、SQL Server 2005 执行下面的Sql查询脚本。该Sql脚本将生成一个新的mike108mvp数据库，里面包含两个表User、UserType。 注意：这个数据库脚本与Demo #4 的脚本一样，如果你已经执行过Demo #4的数据库脚本，则可以跳过这一步。【ok】 数据库sql脚本   Code

}
5、Views/Users/List.aspx 加入下面的代码即可使用MikePager数据分页控件：【ok】 Code
<div class="mike_mvc_pager" >
<%=Html.MikePager<User>(ViewData.Model.PagedList)%>
</div>
6、数据分页代码请看下载的Demo源码Helpers目录下的几个文件。【ok】 （文/mike108mvp 出处/博客园） | 感谢原创者的辛勤劳动，希望对您有所帮助，转载请注明原出处。 |
