I'm using Razor. Here is an example that displays the problem using version 2015.3.930 (tested with IE10 and latest Firefox and Chrome).
View:
@(Html.Kendo().Grid<TelerikMvc5App1.Models.TestDataModel>() .Name("Grid") .Columns(columns => { columns.Bound(e => e.FirstName); columns.Bound(e => e.LastName); columns.Bound(e => e.State) .Filterable(filterable => filterable.UI("stateFilterUsingModel")); }) .Filterable(filterable => filterable .Extra(false) .Operators(operators => operators .ForString(str => str .Clear() .StartsWith("Starts with") .IsEqualTo("Is equal to") .IsNotEqualTo("Is not equal to") ) ) ) .DataSource(dataSource => dataSource .Ajax() .Read(read => read.Action("TestData_Read", "FilterMenuCustomization")) ))<script type="text/javascript"> function stateFilterUsingModel(element) { element.kendoDropDownList({ dataTextField: "Name", dataValuefield: "Name", dataSource: { transport: { read: "@Url.Action("FilterMenuCustomization_StatesUsingModel")" } }, optionLabel: "--Select Value--" }); }</script>Controller:
namespaceKendo.Mvc.Examples.Controllers{ publicclassFilterMenuCustomizationController : Controller { publicActionResult Index() { returnView(); } publicActionResult TestData_Read([DataSourceRequest] DataSourceRequest request) { var list = newList<TestDataModel>(); list.Add(newTestDataModel { FirstName = "Jane", LastName = "Doe", State = "Oregon" }); list.Add(newTestDataModel { FirstName = "John", LastName = "Doe", State = "Oregon" }); list.Add(newTestDataModel { FirstName = "Jimmy", LastName = "John", State = "Washington" }); returnJson(list.ToDataSourceResult(request), JsonRequestBehavior.AllowGet); } publicActionResult FilterMenuCustomization_StatesUsingModel() { var list = newList<TestLookupModel>(); list.Add(newTestLookupModel("Oregon")); list.Add(newTestLookupModel("Washington")); list.Add(newTestLookupModel("Idaho")); list.Add(newTestLookupModel("California")); list.Add(newTestLookupModel("Nevada")); returnJson(list, JsonRequestBehavior.AllowGet); } }}Model:
