Using 2011.1.315 I cannot get the ComboBox to update if one of the items has a blank for the Text value. I either receive a g.slice or e.replace JavaScript error.

I would like to have one entry in the ComboBox display a blank for the Text as if nothing was chosen. Right now I have to remove this blank from the list of items to get the control to function. Is there a work around for this?

here's my view:

<%= Html.Telerik().Grid<EntryList>()

.Name("EntryList")

.DataKeys(keys =>

{

keys.Add(p => p.RaceResultsID);

})

.ToolBar(toolbar => {

toolbar.Insert();

})

.DataBinding(dataBinding =>

{

dataBinding.Ajax()

.Select("_SelectEntryListDrivers", "EntryList")

.Update("_UpdateDriver", "EntryList")

.Insert("_InsertDriver", "EntryList")

.Delete("_DeleteDriver", "EntryList");

})

.Columns(columns =>

{

columns.Bound(p => p.Name).Width(115);

columns.Bound(p => p.Car).Width(40);

columns.Bound(p => p.Manufacturer).Width(75);

columns.Bound(p => p.Sponsor).Width(175);

columns.Bound(p => p.Owner).Width(200);

columns.Command(commands =>

{

commands.Edit();

commands.Delete();

}).Width(75).Title("Actions");

columns.Bound(p => p.PersonID)

.ClientTemplate(Html.ActionLink("Person Edit", "Edit", new { area = "util", controller = "Person", ID = "<#= PersonID #>" }, new { target = "_blank", @class = "t-button" }).ToString()).ReadOnly(true).HtmlAttributes("class='t-button'").Title("Utility").Width(75);

columns.Bound(p => p.RaceResultsID).Width(25).Hidden(true);

columns.Bound(p => p.DriverEntity).Width(25).Hidden(true);

columns.Bound(p => p.OwnerID).Width(25).Hidden(true);

columns.Bound(p => p.NumberID).Width(25).Hidden(true);

columns.Bound(p => p.SponsorID).Width(25).Hidden(true);

columns.Bound(p => p.ManufacturerID).Width(25).Hidden(true);

columns.Bound(p => p.SubSeriesName).Width(5).Hidden(true);

columns.Bound(p => p.VehicleID).Width(5).Hidden(true);

})

.Sortable(sorting => sorting.OrderBy(sortOrder => sortOrder.Add(o => o.Name).Ascending()))

.Reorderable(reorder => reorder.Columns(true))

.ClientEvents(events => events.OnSave("onSave"))

.ClientEvents(events => events.OnEdit("onEdit"))

%>

The Edit Template for the column "Car". It is a list of numerical values from 0 to 99 along with a blank at the top and "none" at the bottom.

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>

<%= Html.Telerik().ComboBox()

.Name("Car")

.DataBinding(binding => binding.Ajax().Select("_SelectCarNumbers", "EntryList"))

.AutoFill(true)

.Filterable(filtering => filtering.FilterMode(AutoCompleteFilterMode.StartsWith).MinimumChars(1))

.HighlightFirstMatch(true)

.ClientEvents(events => events.OnDataBinding("onCarDataBinding"))

%>

The Controller for the Template:

[HttpPost]

public ActionResult _SelectCarNumbers(int eventID)

{

var list = _util.GetOwnerNumberListByID(Int32.MinValue, Int32.MinValue, eventID);

var car = list.AsQueryable();

return new JsonResult { Data = new SelectList(car.ToList(), "NumberID", "NumberText") };

}
