Hello Larry,

Thank you for the update.

The CompactData option doesn't appear to be working as expected. For this reason, I have asked our Product Development team to examine this further. To ensure that it will receive attention, I have logged this behavior in our internal tracking system with a Development ID of 171369.  The next step will be for a developer to review my investigation and confirm my findings or to offer a fix, or other resolution. 

I will be sure to post the resolution onto this forum thread as soon as it is available.

I also tried this in your sample project and it did not work there either. I changed asp-mvc-helper to

    @using (Html.BeginForm())
    {
        <div class="sample-ui">
            @Html.HiddenFor(item => item.OrderID)

            <div>
                <h4>Current Employee:</h4>
                @Html.DisplayFor(item => item.EmployeeName)
            </div>

            <div>
                <h4>Choose New Employee</h4>

                @(Html.Infragistics().ComboFor(item => item.EmployeeID)
                    .Width("270px")
                    .DataSourceUrl(Url.Action("employee-combo-data"))
                    .ValueKey("ID")
                    .TextKey("Name")
                    .ItemTemplate("${Name} Title: ${Title}")
                    .CompactData(false)
                    .DataBind()
                    .Render()
                )
            </div>

            <input id="submitBtn" type="submit" value="Update" />
        </div>
    }
</body>
</html>

It shows the name and the tiitle literal but not the title.

I am using the latest version - 2014.2

I am using the MVC helper:

                                            @(Html.Infragistics().ComboFor(item => item.RentalLocationID)
                                            .Width("100%")
                                            .Height("34px")
                                            .ValueKey("LocationID")
                                            .TextKey("Location")
                                            .ItemTemplate("Branch: ${BranchName}")
                                            .CompactData(false)
                                            .DataSourceUrl(Url.Action("location-combo-data"))
                                            .DataBind()
                                            .Render()
                                            )

With the data model:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace Web.Models
{
    [Serializable]
    public class LocationComboList
    {
        public int LocationID { get; set; }
        public string Location { get; set; }
        public string BranchName { get; set; }
    }
}

With this controller action:

        [ComboDataSourceAction]
        [ActionName("location-combo-data")]
        public ActionResult ComboDataLocation()
        {
            commonRepository = new CommonRepository();
            IEnumerable<LocationComboList> locationComboList = commonRepository.GetLocationsComboList();
            return View(locationComboList);
        }

GetLocationsComboList is filling the model correctly, the problem appears to be returning the model to the view.
