What I have tried:

$(document).ready(function () {
$("#demoGrid").DataTable({
processing: true, // for show progress bar
serverSide: true, // for process server side
filter: true, // this is for disable filter (search box)
orderMulti: false, // for disable multiple column at once
paging: false,
scrollY: 200,
keys: true,

ajax: {
url: "/Demo/LoadData",
type: "POST",
datatype: "json"
},

columnDefs:
[{
targets: [0],//companyID
visible: false,
searchable: false
},
{
targets: [2],//contactname
orderable: false
},

targets: [3],//contactTitle
orderable: false
},

targets: [4],//CIty
orderable: false
},
