JqGrid Search In MVC
This is the next part of jqGrid tutorial, before this we already study the basic examples, pagination and sorting of jqGrid. Here we are learning searching feature in jqGrid.

public class JqGridController : Controller
{

public ActionResult Index()
{
return View();
}
public JsonResult GetStudents()
{
DbStudentEntities db = new DbStudentEntities();
var data = from i in db.Students
select new
{
StudentId = i.StudentId,
Name = i.Name,
Mobile = i.Mobile,
Email = i.Email,
City = i.City,
DOJ = i.DOJ
};
return Json(data, JsonRequestBehavior.AllowGet);
}

$("#tblData").jqGrid({

colModel: [{ name: 'Name', index: 'Name', sorttype: 'text', searchoptions: {sopt:['cn'
]}
},
{ name: 'Mobile', index: 'Mobile', searchoptions: { sopt: ['cn'] } },
{ name: 'Email', index: 'Email', searchoptions: { sopt: ['cn'] } },
{ name: 'City', index: 'City', searchoptions: { sopt: ['cn'] } }],
width: 700,
height: 'auto',

gridview:true,
rowNum: 5,
rowList: [5, 10, 20, 50, 100],
pager: $("#divPager"),
