    main.ashx

    public void ProcessRequest(HttpContext context)
            {
                context.Response.ContentType = "text/html";
                BLL.TUser user = new BLL.TUser();

                context.Response.Write(DBUtility.JsonConvert.DatasetToJson(ds));
            }

    常见错误:

    1.field要一致。

    2.翻页查询

    select top @rows * from TUser where UserID> 
    (select max(UserID) from 
      (select top (@page-1)*@row UserID from TUser order by UserID ASC ) t0
    )
    order by UserID ASC 
    
    /*例子:第2页*/
    select top 10 * from TUser where UserID> 
    (select max(UserID) from 
      (select top 10 UserID from TUser order by UserID ASC ) t0
    )
    order by UserID ASC

     sql 2008(@ROWS_NUMBER)

    select * from  (select *,ROW_NUMBER() over(order by SortId desc) as rownum from RB_Activity)
    ((@page-1) * @rows) and (@page * @rows)
    

      

    3.formatter:编辑按钮

    columns: [[

                            }
                        },
                    ]],
    getRows none 返回当前页的记录。
    function show(i) {
                var row = _datagrid.datagrid('getRows');
                console.info(row[i]);
