将datatables与asp.net c#、LINQ和具有分页器的存储过程一起使用
我将数据库与asp.net、c#、Linq和SQL Server存储过程一起使用，我的过程内部有分页功能，可以获取当前页面的参数 我的aspx代码如下（对于datatables） 这是我的c代码将datatables与asp.net c#、LINQ和具有分页器的存储过程一起使用,c#,asp.net,sql-server,linq,jquery-datatables,C#,Asp.net,Sql Server,Linq,Jquery Datatables,我将数据库与asp.net、c#、Linq和SQL Server存储过程一起使用，我的过程内部有分页功能，可以获取当前页面的参数 我的aspx代码如下（对于datatables） 这是我的c代码 DataClassesErrorsDataContext conx=newDataClasseSerrorsDataContext（）； 列出所有结果= conx.MK_Bad_Gridview_Paging_281_Rejected_linq（页码）.ToList（）； 返回所有结果； PAGE
DataClassesErrorsDataContext conx=newDataClasseSerrorsDataContext（）；
列出所有结果=
conx.MK_Bad_Gridview_Paging_281_Rejected_linq（页码）.ToList（）；
返回所有结果；
PAGENUMBER我确信，存储过程不是通过分页获取网格数据的最方便的方法，因为除了当前页面外，您迟早会传递排序和筛选选项，而这些操作在选择数据页面后无法完成。放弃存储过程，将SQL查询转换为链接查询，使用动态linq来使用字符串表达式。如果需要，我可以写一个c#示例代码。然而，在我看来，没有什么比ExtJS GridPanel更好的发明了J使用SQL server存储过程查询数据表
通过动态高效的分页结构，
支持所有服务器版本
