JQuery数据表服务器端用SQL Server实现ASP.NET
正在寻找一个使用ASP.NET和jQuery Datatable实现的简单示例。首先，您需要了解数据表及其参数的基本知识。 在ajax上，它向目标方法发送一些参数，并获取四个参数以在数据表中显示数据。我使用了包含参数的DTParameters 行动方法：JQuery数据表服务器端用SQL Server实现ASP.NET,jquery,asp.net,sql-server,datatable,Jquery,Asp.net,Sql Server,Datatable,正在寻找一个使用ASP.NET和jQuery Datatable实现的简单示例。首先，您需要了解数据表及其参数的基本知识。 在ajax上，它向目标方法发送一些参数，并获取四个参数以在数据表中显示数据。我使用了包含参数的DTParameters 行动方法： [HttpPost] public ActionResult loadData(DTParameters param) { //Us IQuerable for server

其他的

}
IQueryable<ClassName> result = dbconText.tbleName ; // return type to be IQueryable
var dtaTableResult = result.ToDataTableList(param.Draw, param.Start, param.Length);
return dtaTableResult;
Make Extension Method ,
public static class QueryablExtensions
{
public static DTResult<T> ToDataTableList<T>(this IQueryable<T> query, int draw, int skip, int take)
{
var count = query.Count();
var list = query.Skip(skip).Take(take).ToList();
return new DTResult<T>(list, draw, count, count);
}
}
IQueryable结果=dbconText.tbleName；//返回类型为IQueryable
var dtatablesult=result.ToDataTableList（param.Draw、param.Start、param.Length）；
返回dtaTableResult；
做延伸法,，
公共静态类QueryablExtensions
{
公共静态DTResult ToDataTableList（此IQueryable查询、int-draw、int-skip、int-take）
{
var count=query.count（）；
var list=query.Skip（Skip）.Take（Take.ToList（）；
返回新的DTResult（列表、绘制、计数、计数）；
}
