javascript - Why don't jquery datatable get filled with newly updated data after searching? -

i filling jquery datatable (ver: 1.10.15) webapi , works when search in datatable via searchbox doesn't fill datatable updated data. why?

i checked, sends search value , brings updated data server doesn't populate table newly returned data.

function show() {                                  $('#example').datatable({ //  "processing": true,     "serverside": true,     "retrieve": true,     "destroy": true,     "pagination": true, //  "contenttype": 'application/json; charset=utf-8',     "ajax": "http://localhost:28071/users"   }); } 

update:

c# api code:

namespace webapihimher.controllers {     public class userscontroller : apicontroller     {         [httpget]         public dtresult getdata([fromuri]dtparameters v)         {              list<string[]> s = new list<string[]>();              //list<basicoperations> s = new list<basicoperations>();              basicoperations bo= new basicoperations();               s = bo.getusers(v.length, v.start, 1, v.sortorder, v.search.value);              dtresult r = new dtresult();             r.draw = 1;             r.recordsfiltered = s.count;             r.recordstotal = 100; ;             r.data = s;              return r;         }     }      public class dtresult     {         public int draw { get; set; }         public int recordstotal { get; set; }         public int recordsfiltered { get; set; }         public list<string[]> data { get; set; }     }     public abstract class dtrow     {         public virtual string dt_rowid         {             { return null; }         }         public virtual string dt_rowclass         {             { return null; }         }         public virtual object dt_rowdata         {             { return null; }         }     }     public class dtparameters     {         public int draw { get; set; }         public dtcolumn[] columns { get; set; }         public dtorder[] order { get; set; }         public int start { get; set; }         public int length { get; set; }         public dtsearch search { get; set; }         public string sortorder         {                         {                 return columns != null && order != null && order.length > 0                     ? (columns[order[0].column].data + (order[0].dir == dtorderdir.desc ? " " + order[0].dir : string.empty))                     : null;             }         }     }     public class dtcolumn     {         public string data { get; set; }         public string name { get; set; }         public bool searchable { get; set; }         public bool orderable { get; set; }         public dtsearch search { get; set; }     }     public class dtorder     {         public int column { get; set; }         public dtorderdir dir { get; set; }     }     public enum dtorderdir     {         asc,         desc     }     public class dtsearch     {         public string value { get; set; }         public bool regex { get; set; }       }  } 

i posting request , response after initial table load , after performing search

after initial load:

• request:

_ 1503560388132 columns[0][data] 0 columns[0][name] columns[0][orderable] true columns[0][search][regex] false columns[0][search][value] columns[0][searchable] true columns[1][data] 1 columns[1][name] columns[1][orderable] true columns[1][search][regex] false columns[1][search][value] columns[1][searchable] true draw 2 length 10 order[0][column] 0 order[0][dir] asc search[regex] false search[value] 2 start 0

response:

{"draw":1,"recordstotal":4,"recordsfiltered":25,"data":[["hunain","123"],["hk","asd"],["daenerys targaryen" ,"123"],["",""]]}

after performing search:

• request:

_ 1503560409319 columns[0][data] 0 columns[0][name] columns[0][orderable] true columns[0][search][regex] false columns[0][search][value] columns[0][searchable] true columns[1][data] 1 columns[1][name] columns[1][orderable] true columns[1][search][regex] false columns[1][search][value] columns[1][searchable] true draw 2 length 10 order[0][column] 0 order[0][dir] asc search[regex] false search[value] w start 0

• response:

{"draw":1,"recordstotal":1,"recordsfiltered":25,"data":[["waleed","123"]]}

the reason draw parameter being sent , received not same because took draw static in server code mismatched. returned same draw parameter sent.

---

from docs :

the draw counter object response - draw parameter sent part of data request. note recommended security reasons cast parameter integer, rather echoing client sent in draw parameter, in order prevent cross site scripting (xss) attacks.
