我正在使用MVC3中的KendoUI MVC。
我设法在网格列中获得一个下拉列表。但我不清楚如何设置所选值,当我保存它时不会保存我选择的值。
网格
@using Perseus.Areas.Communication.Models
@using Perseus.Common.BusinessEntities;
<div class="gridWrapper">
@(Html.Kendo().Grid<CommunicationModel>()
.Name("grid")
.Columns(colums =>
{
colums.Bound(o => o.communication_type_id)
.EditorTemplateName("_communicationDropDown")
.ClientTemplate("#: communication_type #")
.Title("Type")
.Width(180);
colums.Bound(o => o.sequence).Width(180);
colums.Bound(o => o.remarks);
colums.Command(command => command.Edit()).Width(50);
})
.Pageable()
.Sortable()
.Filterable()
.Groupable()
.Editable(edit => edit.Mode(GridEditMode.InLine))
.DataSource(dataSource => dataSource
.Ajax()
.ServerOperation(false)
.Model(model => model.Id(o => o.communication_id))
.Read(read => read.Action("AjaxBinding", "Communication", new { id = @ViewBag.addressId }))
.Update(update => update.Action("Update", "Communication"))
.Sort(sort => { sort.Add(o => o.sequence).Ascending(); })
.PageSize(20)
)
)
</div>
EditorTemplate“_communicationDropDown
@model Perseus.Areas.Communication.Models.CommunicationModel
@(Html.Kendo().DropDownListFor(c => c.communication_type_id)
.Name("DropDownListCommunication")
.DataTextField("description1")
.DataValueField("communication_type_id")
.BindTo(ViewBag.CommunicationTypes))

我认为这是一个重要的指出是DropDownList名称应该与列名属性匹配。 html属性name =“”,而不是列的标题。名称属性必须匹配才能生效,因为您正在使用来自编辑器模板的另一个控件替换默认编辑器控件以在编辑操作期间取代它。如果在将DOM序列化回模型以进行更新操作时名称不匹配,则将忽略编辑器模板控件中的值。默认情况下,它是出现在模型类中的属性变量名称,除非在标记中覆盖。
(编辑答案以包括插入记录操作)。
这是一个有效的例子:
模特课程:
public class Employee
{
public int EmployeeId { get; set; }
public string Name { get; set; }
public string Department { get; set; }
}
查看:
@(Html.Kendo().Grid<Employee>()
.Name("Grid")
.Columns(columns =>
{
columns.Bound(p => p.Name).Width(50);
columns.Bound(p => p.Department).Width(50).EditorTemplateName("DepartmentDropDownList");
columns.Command(command => command.Edit()).Width(50);
})
.ToolBar(commands => commands.Create())
.Editable(editable => editable.Mode(GridEditMode.InLine))
.DataSource(dataSource => dataSource
.Ajax()
.Model(model => model.Id(p => p.EmployeeId))
.Read(read => read.Action("GetEmployees", "Home"))
.Update(update => update.Action("UpdateEmployees", "Home"))
.Create(create => create.Action("CreateEmployee", "Home"))
)
)
部分视图编辑器模板,文件名“DepartmentDropDownList”,位于特定于此视图的EditorTemplates文件夹中。即。主页\视图\ EditorTemplates \ DepartmentDropDownList.cshtml
@model string
@(Html.Kendo().DropDownList()
.Name("Department") //Important, must match the column's name
.Value(Model)
.SelectedIndex(0)
.BindTo(new string[] { "IT", "Sales", "Finance" })) //Static list of departments, can bind this to anything else. ie. the contents in the ViewBag
读取操作的控制器:
public ActionResult GetEmployees([DataSourceRequest]DataSourceRequest request)
{
List<Employee> list = new List<Employee>();
Employee employee = new Employee() { EmployeeId = 1, Name = "John Smith", Department = "Sales" };
list.Add(employee);
employee = new Employee() { EmployeeId = 2, Name = "Ted Teller", Department = "Finance" };
list.Add(employee);
return Json(list.ToDataSourceResult(request));
}
更新操作的控制器:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult UpdateEmployees([DataSourceRequest] DataSourceRequest request, Employee employee)
{
return Json(new[] { employee }.ToDataSourceResult(request, ModelState));
}
创建操作的控制器:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult CreateEmployee([DataSourceRequest] DataSourceRequest request, Employee employee)
{
employee.EmployeeId = (new Random()).Next(1000);
return Json(new[] { employee }.ToDataSourceResult(request, ModelState));
}
