<%: Html.Kendo().Grid<SSTS.Models.FaresBasedViewModel>()
.Name("grid2")
.Columns(columns =>
{
columns.ForeignKey(p => p.StudentNumber, (System.Collections.IEnumerable)ViewData["students"], "StudentNumber", "StudentNumber")
.Title("StudentNumber").Width(150);
columns.Bound(student => student.GivenName).Width(150);
columns.Bound(student => student.DateGovernmentFunded).Width(150);
columns.Bound(student => student.SectionNumber).Width(150); ;
columns.Bound(student => student.Description).Width(150);
columns.Bound(student => student.Distance).Width(150);
columns.Bound(student => student.FareNumber).Width(150);
columns.Bound(student => student.FareType).Width(150);
columns.Bound(student => student.TopeUpCode).Width(150);
columns.Bound(student => student.ApplicationID).Width(150);
columns.Command(commands =>
{
commands.Edit();
commands.Destroy();
}).Title("Commands").Width(150);
})
.ToolBar(toolbar => toolbar.Create())
.Editable(editable => editable.Mode(GridEditMode.InLine))
.DataSource(dataSource =>
dataSource.Ajax()
.Events(events => events.Change("change"))
.Model(model =>
{
model.Id(student => student.FareBaseID);
model.Field(p => p.StudentNumber).DefaultValue("");
})
.Create(create => create.Action("FaresBased_Create", "ServiceUse"))
.Read(read => read.Action("FaresBased_Read", "ServiceUse"))
.Update(update => update.Action("FaresBased_Update", "ServiceUse"))
.Destroy(destroy => destroy.Action("FaresBased_Destroy", "ServiceUse"))
)
.Pageable().Scrollable()
%>
function change(e) {
if (e.field == "StudentNumber") {
var model = e.items[0];
model.set("GivenName", model);
}
}

以下是我如何使用DropDownList过滤网格的示例。
@{
ViewBag.Title = "Contacts";
var customerId = ViewContext.RouteData.Values["id"];
}

.Grid<Fss.Areas.Customers.Models.Contact>()

.Columns(columns =>
{
columns.Bound(c => c.Active).ClientTemplate("<input type=\"checkbox\" disabled=\"disabled\" value=\"#= ContactId #\" # if (Active) { #checked='checked'# } #/>");
columns.Bound(c => c.LastName);
columns.Bound(c => c.FirstName);
columns.Bound(c => c.Email);
columns.Bound(c => c.Phone);
columns.Bound(c => c.Mobile);
columns.Bound(c => c.Changed).Format("{0:HH:mm:ss d/M/yyyy}");
columns.Bound(c => c.ChangedBy);
columns.Command(command =>
{
command.Edit();
command.Destroy();
}).Width(172);
})
