I am trying to implement a multi-column AutoComplete. My first attempt with my own code and models was not showing with any items even though I expected it to. So, I then copied one the examples in your documentation but am still not able to see any items in the AutoComplete. This is the exapmple that I used, https://help.syncfusion.com/aspnetmvc/autocomplete/multicolumn. It says that it uses a datasource from another example, "@*Refer to the DataSource defined in Local Databinding Step 1 *@". So, I went to AutoComplete->Data Binding->Local Data to get the code for the data source in that example, https://help.syncfusion.com/aspnetmvc/autocomplete/data-binding. I used that same C# code to populate the object for the data source but the only difference is I assigned/used a property on my view model to hold it instead of the ViewBag. When I run this example, no matter what I type in the AutoComplete, I always am getting "No Results". I then thought that I would set this property on the AutoComplete to see what items were being rendered, ".ShowPopupButton(true)", so that I could click the magnifying glass image to see the items as a drop down. But, when I did this there were, I would estimate, the same amount of rows as items in my dataset. But, each column was blank and there were 84 columns I think, when there only should have been two, and there werenot the proper column headings as defined in the razor. The column headings were "column1", "column2", etc., up to 84. I am pasting my copied* example code. Can you tell me what I am doing wrong that is causing me to not see any items?

*The razor in the example was missing the ".Render()". I have added that. The razor in the example listed the field names in camel case. I have changed them to upper case.

Razor
--------
 @{
            Html.EJ().Autocomplete("autocomplete")
                .Datasource(Model.Cars)
                .MultiColumnSettings(obj => obj.Enable(true).Columns(obj1 =>
                {
                    obj1.Field("UniqueKey").HeaderText("Unique Key").Add();
                    obj1.Field("Text").HeaderText("Text").Add();
                }).ShowHeader(true).StringFormat("{0} ({1})")).Render();
        }

C# Controller
----------------
---------------------------------------------------------------
Model in example
---------------------------------------------------------------
public class CarsList
{
    public int UniqueKey { get; set; }
    public string Text { get; set; }
}

---------------------------------------------------------------
Property in view model
---------------------------------------------------------------
public List<CarsList> Cars { get; set; }

---------------------------------------------------------------
Object that is assigned to the property on the view model
---------------------------------------------------------------
var cars = new List<CarsList>();
cars.Add(new CarsList { UniqueKey = 1, Text = "Audi S6" });
cars.Add(new CarsList { UniqueKey = 2, Text = "Austin-Healey" });
cars.Add(new CarsList { UniqueKey = 3, Text = "Alfa Romeo" });
cars.Add(new CarsList { UniqueKey = 4, Text = "Aston Martin" });

Hi Jason,    
Thanks for contacting Syncfusion support. 
We were unable to reproduce the mentioned issue with multi-column Autocomplete, using the shared code snippet. Hence, we have now prepared a sample by using the view model and bind data source using Model. Please find the below code snippet. 
[Model] 
public class CarsList 
    { 
        public int UniqueKey { get; set; } 
        public string Text { get; set; } 
        public string company { get; set; } 
    } 
 
    public class Viewmodel 
    { 
        public List<CarsList> Cars { get; set; } 
    } 
 
[Controller] 
var cars = new List<CarsList>(); 
 
            cars.Add(new CarsList { UniqueKey = 1, Text = "Audi S6" });               
             . 
             . 
             . 
             . 
            cars.Add(new CarsList { UniqueKey = 36, Text = "Saab Sportcombi" }); 
 
            Viewmodel obj = new Viewmodel(); 
 
            obj.Cars = cars; 
 
            return View(obj); 
[View] 
@Html.EJ().Autocomplete("selectcar").Width("50%").Datasource((IEnumerable<SyncfusionMVC.Models.CarsList>)Model.Cars).MultiColumnSettings(obj => obj.Enable(true).Columns(obj1 => 
{ 
    obj1.Field("UniqueKey").HeaderText("Unique Key").Add(); 
    obj1.Field("Text").HeaderText("Text").Add(); 
}).ShowHeader(true).StringFormat("{0} ({1})")).ShowPopupButton(true) 
 
Please refer our attached sample below for further reference: 
 
Regards, 
Arun P

I copied the code that you put in the reply into my project and still got that same results (not able to see any items). But, I then opened your attached sample and it correctly showed the results. So, it must be something in my project that is conflicting and causing it to not work. I am going to compare your provided example with my project to see if I can notice the differences. Thanks for the example. I will try to report back if I find anything.
