issue with filterToolbar in jqGrid Search - asp.net-mvc

Question

search functionality is not working. when hitting action method in controller parameters looking like "_search=true", "searchField=null", "searchString=null" ,"searchOper=null", here i am not getting values of searchField,searchString,searchOper. Please can any one help.
if i give loadonce: true property then search is working. but i am getting first page records only. i am not getting other page records. How can i fix this.
My code:
$(function () {
$("#Channelslistgrid").jqGrid({
colNames: ['ChannelName', 'Description', 'status'],
colModel: [
{ name: 'ChannelName', index: 'ChannelName', sortable: true, align: 'left', width: '200',
editable: false, edittype: 'text',search:true
},
{ name: 'Description', index: 'Description', sortable: false, align: 'left', width: '120',
editable: false, edittype: 'text',search:true
},
{ name: 'status', index: 'status', sortable: false, align: 'left', width: '220',
editable: false, edittype: 'text',search:true
},
],
pager: jQuery('#pager'),
sortname: 'Title',
rowNum: 15,
rowList: [15, 20, 25],
sortorder: "desc",
height: 345,
ignoreCase: true,
viewrecords: true,
rownumbers: true,
caption: 'Channels List',
width: 660,
url: "#Url.Content("~/Home/Channelslist")",
datatype: 'json',
mtype: 'GET',
loadonce: true
})
jQuery("#Channelslistgrid").jqGrid('filterToolbar', { searchOnEnter: true, enableClear: false });
});
controller
public ActionResult Channelslist(int page, int rows, string sidx, string sord, bool _search, string searchField, string searchString, string searchOper)
{
//code
}

Instead you can use the below controller code to get the search parameters typed on the filtertoolbar.
public ActionResult Channelslist(int page, int rows, string sidx, string sord, bool _search) {
string ChannelName= "";
string desc= "";
if (Request.Params["ChannelName"] != null) ChannelName = Request.Params["ChannelName"];
if (Request.Params["Description "] != null) desc= Request.Params["Description"];
}
