如何在mvc视图中按日期列出数据顺序

Question

Iam using mvc, i want to retreive data in index view order by date.

var cn = from a in db.table1 
         join b in db.table2 on a.Country equals b.CountryCode
         join c in db.table3 on a.DealerId equals b.CompID  
         order by a.date desc select a;

return View(cn.ToList());

without datatables it is working fine, but datatables not allowing to sort by date. it is only displaying the data by primary key value order Any help will be greatly appreciated.

Answer 1

您可以使用linq orderby，例如：

.OrderByDescending(x => x.Date);

Answer 2

$(document).ready(function() {
            $('#id').dataTable( {
                "aaSorting": [[ 2, "desc" ]]  //2 - number of column
            } );
        } );

if you dont want to display the date column through which you are sorting then use

"aaSorting": [[12, "desc"]],
        "aoColumnDefs": [{ "bVisible": false, "aTargets": [12] }],

upto this level it will sort only columns which are in datatable so u need to use linq query

return view(cn.OrderByDescending.ToList());

Answer 3

Look at this example of usage.
Set "aaSorting" attribute to sort by date.

$(document).ready(function() {
            $('#youTableId').dataTable( {
                "aaSorting": [[ 2, "desc" ]]  //2 - number of column
            } );
        } );
