如何使用C#,ASP.NET,SQL Server端处理实现jQuery DataTables插件？

Question

如何使用C#,ASP.NET,使用ajax和webservices进行SQL Server端处理来实现jQuery DataTables插件？

想使用c#和ASP.NET实现Datatables网格,但很难找到一个有效的例子.

Answer 1

JQuery DataTables在C#,ASP.NET,SQL Server端处理中使用ajax和webservices的工作示例.

(发布两次以便让想要找到它的人更容易)

通过链接到DataTables.Net开始,Allan使用这个插件做了一个了不起的工作.

我一直在使用这个插件大约一年.当我第一次尝试使用服务器端处理,ajax和webservices在C#和.NET中实现它时,几乎没有文档和工作示例,所以我决定将它们放在一起.

提供的源代码是Visual Studio 2012(在Ultimate 2012和Pro 2012中测试)网站项目.我把它作为一个简单的工作示例扔在一起,希望能帮助其他人试图将这样的东西放在一起.这是我希望我一年前拥有的东西.

数据库mdf包含在App_Data文件夹中.我目前正在运行MS SQL Server Express 2012的实例.

必需安装SQL Server Express 2012或其他标准或更好的完整版MS SQL Server安装.在标准2008 R2和2012 Express上测试.

Answer 2

此版本适用于较旧的SqlServer,对于较新版本,请尝试另一个版本.

此技术使用存储过程,您可以通过使用除#temp主要功能之外的其他方法来提高性能

• 存储过程
• 注入免费且易于适应的sql结构
• 阿贾克斯

功能性和非常有用

第1步:(HTML)

 <link href="../Content/css/datatables.min.css" rel="stylesheet" />
 <script src="../Scripts/datatables.min.js"></script>
 <script src="../Scripts/jQuery-2.1.4.min.js"></script>

 <script>
 $(document).ready(function () {
      if ($.fn.dataTable.isDataTable('#tbl_category')) {
        t.destroy();
    }
    t = $("#tbl_category").DataTable({
        processing: true,
        serverSide: true,
        info: true,
        ajax: {
            url: '../Ajax/Category?option=GetAllAdminCategory&user_srno='+user_srno,
            data: function (data) {
                delete data.columns;
            }
        },
        columns: [
                    { "data": "abc" },
                    { "data": "name" },
                    { "data": "baseDiscount" },
                    { "data": "additionalDiscount" },
                    { "data": "specialDiscount" },
                    {
                        "render": function (data, type, full, meta) {
                            return '<a class="btn btn-warning" onClick="editdata(' + full.srno + ',\'' + full.name + '\',\'' + full.baseDiscount + '\',\'' + full.additionalDiscount + '\',\'' + full.specialDiscount + '\',\'' + full.specialDiscount + '\')" href="javascript://">Edit</a>&nbsp;&nbsp;<a class="btn btn-danger" onClick="deletePhantom(' + full.srno + ',\'DELETE\')" href="javascript://">Remove</a>';
                        }
                    }
        ],
        order: [[0, 'desc']],
        select: true,
        dom: 'lfrtip',
        responsive: true,
        buttons: true
    });
    t.on('order.dt search.dt', function () {
        t.column(0, { search: 'applied', order: 'applied' }).nodes().each(function (cell, i) {
            cell.innerHTML = i + 1;
        });
    }).draw();

});
 </script>

 <table id="tbl_category" class="display" cellspacing="0" width="100%">
                        <thead>
                            <tr>
                                <th>#</th>
                                <th>Name</th>
                                <th>Base Discount</th>
                                <th>Additional Discount</th>
                                <th>Special Discount</th>
                                <th>Action</th>
                            </tr>
                        </thead>
                        <tfoot>
                            <tr>
                                <th>#</th>
                                <th>Name</th>
                                <th>Base Discount</th>
                                <th>Additional Discount</th>
                                <th>Special Discount</th>
                                <th>Action</th>
                            </tr>
                        </tfoot>
                    </table>

步骤:2(存储过程)

Create procedure [dbo].[category_post]

 @user_srno int=null,
 @catSrno int=null,
 @name varchar(200)=null,
 @baseDiscount numeric(18,2)=null,
 @additionalDiscount numeric(18,2)=null,
 @specialDiscount numeric(18,2)=null,
 @status int null,
 @Action_by int null,
 @option varchar(20) = null, -- to here personnel parameters
 @orderColumn  int =null, 
 @orderDir  varchar(20)=null,
 @start  int =null,
 @limit  int =null,
 @searchKey varchar(20) -- personnel parameter
  as 
  BEGIN



    select IDENTITY(int,1,1) as SnoID, null as abc,specialDiscount, additionalDiscount, baseDiscount, name,cast(srno as varchar(20)) as srno
            --this method is userful for all sql server version (it can be made better by using fetch)
    into #tempCategory
     from categoryStd where [status] not in(4,14) and categoryStd.name like '%'+@searchKey+'%'

    declare @to as int = @start+@limit  

     select * from #tempCategory where SnoID>@start and SnoID<=@to

        order by
                    CASE WHEN @orderColumn = 1 AND @orderdir = 'desc' THEN #tempCategory.[name] END DESC,
                    CASE WHEN @orderColumn = 1 AND @orderdir = 'asc' THEN #tempCategory.[name] END ASC,
                    CASE WHEN @orderColumn = 2 AND @orderdir = 'desc' THEN #tempCategory.[name] END DESC,
                    CASE WHEN @orderColumn = 2 AND @orderdir = 'asc' THEN #tempCategory.[name] END ASC



        select count(*) from #tempCategory

      // or user your own method to get data (just fill the dataset)

      //  DataSet ds = cmnCls.PRC_category(CatgObj);

        dynamic newtonresult = new
          {
