              .Name("customers")
              .Placeholder("Select customer")
              .DataTextField("CustName")
              .DataValueField("CustomerID")
              .Columns(columns =>
              {
                  columns.Add().Field("CustName").Title("Name");
                  columns.Add().Field("CustomerID").Title("ID");
              })
              .HtmlAttributes(new { style = "width:100%;" })
              .Filter("contains")
              .AutoBind(false)
              .MinLength(2)
              .DataSource(source =>
              {
                  source.Read(read =>
                  {
                      read.Action("GetCustomers", "OrderManagement");
                  })
                  .ServerFiltering(true);
              })

Controller

 

 public ActionResult GetCustomers(string text)
        {
            ApplicationDbContext db = new ApplicationDbContext();
            var customers = db.Customers.Select(customer => new Customer
            {
                CustomerId = customer.CustomerId,
                CustName = customer.CustName,
                PhoneNo = customer.PhoneNo
            });

            if (!string.IsNullOrEmpty(text))
            {
                customers = db.Customers.Where(p => p.CustName.Contains(text));
            }
           // return Json(GetOrders().ToDataSourceResult(request), JsonRequestBehavior.AllowGet);
            return Json(customers, JsonRequestBehavior.AllowGet);
        }

Hello Suman,

I have reviewed the code snippet provided and the configuration of the MultiColumnComboBox looks correct. That being said, could you elaborate in more details on what the exact issue is so that I am able to continue my investigation?

You could also refer to the following MultiColumnComboBox Demo for ASP.NET MVC where a similar scenario with server filtering is also demonstrated:

I am looking forward to hearing from you.
