本文详细介绍了如何创建数据库表、添加数据，并利用MVC框架实现数据展示和搜索功能。通过实例展示了如何使用ORM技术和分页显示员工信息。

1. 创建数据表

create table Department
(
	DepartmentId int,
	DepartNo varchar(200) primary key,
	DepartName varchar(200),
	ParentID int,
	Remark text
)
create table Employee
(
	EmployeeNo varchar(20) primary key,
	EmployeeName varchar(100),
	Sex char(2),
	Birthday datetime,
	Marital varchar(10),
	DepartmentID int
)

insert into Department values(1,'1','Business1',0,'No')
insert into Department values(2,'2','Business2',1,'No')
insert into Department values(3,'3','Business3',2,'No')
insert into Department values(4,'4','Business4',2,'No')
insert into Department values(5,'5','Business5',2,'No')
insert into Department values(6,'6','Business6',2,'No')
insert into Department values(7,'7','Business7',2,'No')
insert into Department values(8,'8','Business8',2,'No')
insert into Department values(9,'9','Business9',2,'No')
 
insert into Employee values('1001','name1','1','1988-08-31','no',1)
insert into Employee values('1002','name2','1','1988-08-31','no',2)
insert into Employee values('1003','name3','1','1988-08-31','no',1)
insert into Employee values('1004','name4','1','1988-08-31','no',1)
insert into Employee values('1005','name5','1','1988-08-31','no',1)
insert into Employee values('1006','name6','1','1988-08-31','no',1)
insert into Employee values('1007','name7','1','1988-08-31','no',1)
insert into Employee values('1008','name8','1','1988-08-31','no',1)
insert into Employee values('1009','name9','1','1988-08-31','no',1)

2. 添加引用mvccontrib,下载地址为http://mvccontrib.codeplex.com/

3. 在Models中添加Model.dbml

4. 在controller中添加ContribController,代码如下：

   public class ContribController :BaseController
    {
        //
        // GET: /Contrib/

        public ActionResult Index(int? page,GridSortOptions model)
        {
            ViewBag.model = model;
            IEnumerable<Employee> list = DataContext.Employees;
            if(!string.IsNullOrEmpty(model.Column))
            {
                list = list.OrderBy(model.Column,model.Direction);
            }
           list = list.AsPagination(page ??1,5);
            return View(list);
        }
    }
    public class BaseController:Controller
    {
        private ModelDataContext _DataContext = null;
        protected ModelDataContext DataContext
        {
            get
            {
                if(_DataContext==null)          
                    _DataContext = new ModelDataContext();
                    var options = new DataLoadOptions();
                    options.LoadWith<Employee>(p => p.EmployeeNo);
                    _DataContext.LoadOptions = options;
                    return _DataContext;
                
            }
        }

    }

5 右击添加视图Views,添加Index页面

@*@model IEnumerable<MVCPage.Models.Employee>*@
@model IPagination<MVCPage.Models.Employee>

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>
    Index</h2>
@using MvcContrib.UI.Grid
@using MvcContrib.Pagination;
@using MvcContrib.UI.Pager;
@*@Html.Grid(Model).Columns(column =>
{
    column.For(p=>p.EmployeeNo).Named("编号");
    column.For(p=>p.EmployeeName).Named("姓名");
    column.For(p=>p.Sex=="1"?"男":"女").Named("性别");
    column.For(p=>p.Birthday).Format("{0:yyyy/MM/dd}").Named("出生年月");  // 格式化数据
    column.For(p=>p.Marital=="1"?"是":"否").Named("是否婚配");  // 三级运算符
}).Attributes(@width => "100%", @border => "1", @style => "text-align:center;border-collapse:collapse");*@

@Html.Grid(Model).Sort(ViewBag.model as GridSortOptions).Columns(column =>
{
    column.For(p=>p.EmployeeNo).Named("编号");
    column.For(p=>p.EmployeeName).Named("姓名");
    column.For(p=>p.Sex=="1"?"男":"女").Named("性别").Sortable(false);
    column.For(p=>p.Birthday).Format("{0:yyyy/MM/dd}").Named("出生年月");  // 格式化数据
    column.For(p=>p.Marital=="1"?"是":"否").Named("是否婚配").Sortable(false);  // 三级运算符
}).Attributes(@width => "100%", @border => "1", @style => "text-align:center;border-collapse:collapse")
@Html.Pager(Model).First("First").Next("Next").Previous("Previous").Last("Last").Format("Total{2},Current{0}-{1}")

6. 修改Global中路由，注意开始添加引用
