截图:

页面:

<body>
    <form id="form1" runat="server">
    <table id="tt">
        
    </table>
    
  
    </form>
</body>

引用的JS:

<link rel="stylesheet" type="text/css" href="../../script/themes/default/easyui.css" />
    <link rel="stylesheet" type="text/css" href="../../script/themes/icon.css" />
    <script type="text/javascript" src="../../script/jquery-1.4.2.min.js" </script>
    <script type="text/javascript" src="../../script/jquery.easyui.min.js" </script>
    <script type="text/javascript" src="../../script/locale/easyui-lang-zh_CN.js" mce_src="script/locale/easyui-lang-zh_CN.js"></script>

JS:

<script type="text/javascript"><!--
        $(function(){
            $('#tt').datagrid({
                810,
                height:400,
                idField:'xsbh',

                singleSelect:true,
                columns:[[

                    }
                  }
                ]],
                toolbar:[{
                    text:'增加',iconCls:'icon-add',handler:function(){
                        window.location.href='StuAdd.aspx';
                    }
                },
                {text:'导入',iconCls:'icon-add',handler:function(){
                    window.location.href='StuImport.aspx'
                    }

                ],
               pagination:true
            });
        })
        
          function view(bh)  //转到查看页面
            {
                window.location.href='StuView.aspx?id='+bh+'&page=stu';
//              var row = $('#tt').datagrid('getSelected');
//               if(row)
//               {
//                  alert(row.xsbh);
//               }
            }
          function edit(bh)  //转到编辑页面
          {
                window.location.href='StuEdit.aspx?id='+bh;
          }
          
          function del(index){  //删除操作
            $.messager.confirm('确认','确认删除?',function(row){
                if(row){
                    var selectedRow = $('#tt').datagrid('getSelected');  //获取选中行
                    $.ajax({
                        url:'delHandler.ashx?id='+selectedRow.xsbh+'&type=stu',  
//加了个type，作用是以后不管什么删除，都可以转到这个ashx中处理
                        success:function(){alert('删除成功');}
                    });
                    $('#tt').datagrid('deleteRow',index);
                }
            })
          }
    
// --></script>

这里面要注意的是，"操作"的跨行，一定要带上field:'opt',当然，field可以是任何值，这个值不用从数据库中绑定，随便取.如果没有field的话，会弹出 "rowspan为空或不是对象"的错误

获取数据和分页ashx:

using System;
using System.Web;
using System.Data;
using System.Text;

public class studentHandler : IHttpHandler {
    
    public void ProcessRequest (HttpContext context) {
        context.Response.ContentType = "text/plain";
        DataSet ds = new DataSet();
        //点击datagrid的分页按钮，自动向后台发送2个参数,rows和page，代表每页记录数和页索引
        int row = int.Parse(context.Request["rows"].ToString());
        int page = int.Parse(context.Request["page"].ToString());
        ds = GetContent(row, page);
        string text =json.Dataset2Json(ds);
        context.Response.Write(text);
    }

    private DataSet GetContent(int pagesize,int pageindex)
    {
        Graduate.BLL.Student bll = new Graduate.BLL.Student();
        return bll.GetList(pagesize, pageindex);
    }
    public bool IsReusable {
        get {
            return false;
        }
    }

}

删除ashx

using System;
using System.Web;
using System.Web.SessionState;

public class delHandler : IHttpHandler,IRequiresSessionState {
    
    public void ProcessRequest (HttpContext context) {
        context.Response.ContentType = "text/plain";
        string id = context.Request["id"].ToString();
        string type = context.Request["type"].ToString();
        switch (type)
        { 
            case "stu":
                Graduate.BLL.Student stubll = new Graduate.BLL.Student();
                stubll.Delete(id, HttpContext.Current.Session["username"].ToString(), HttpContext.Current.Session["usertype"].ToString());
                break;
            default:
                break;
        }
    }

    public bool IsReusable {
        get {
            return false;
        }
    }

}

IRequiresSessionState 是因为用到了服务器端的session，没有用到的话可以去掉
