我到处搜索（轻描淡写）寻找我的案子的解决方案，直到现在都无济于事。首先，我将解释我的场景：
- 我有一个作为 WCF 数据服务 (oData v3) 公开的 OpenAccess 模型；
- 我有一个 Kendo MVC 应用程序；
- 我有一个带有网格的视图，设置为弹出编辑，AJAX Bound；
在发布一些代码之前，让我解释一下我的问题/困难。我有一个具有这些属性的实体：
- 文本标识
- 标题;
- 公司;
- TipoTextoID;
- 提示文本；
有一个 ForeignKey 列设置为 TipoTextoID 属性，该属性可以在内联或弹出模式下正确填充。但是当涉及到更改数据时，它仅适用于在线模式。这是我的问题，我需要它在弹出窗口中工作，因为“Corpo”属性绑定到 KEndoUI 编辑器。
在弹出窗口中，它不会在下拉列表中显示正确的值，也不会在我们选择它时更改它。
老实说，我觉得我很愚蠢。我尝试了几乎所有我找不到的样本、帖子、文章，但我一无所知。
我希望有人可以帮助我。在此先感谢大家！
所以，这里是代码。风景：
@model IEnumerable<KendoMVC.CostSimulatorService.Texto>
@{
ViewBag.Title = "Textos";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>Textos</h2>
@(Html.Kendo().Grid(Model) // Bind the grid to the Model property of the view
.Name("Grid")
.Columns(columns =>
{
columns.Bound(p => p.Titulo); //Create a column bound to the "ProductID" property
//columns.Bound(p => p.IsPrivado).ClientTemplate("<input type='checkbox' #= IsPrivado ? checked='checked': '' # class='chkbx' />"); //Create a column bound to the "ProductName" property
columns.Template(@<text></text>).ClientTemplate("<input type='checkbox' #= IsPrivado ? checked='checked': '' # class='chkbx' />"); //Create a column bound to the "ProductName" property
//columns.Bound(p => p.TiposTexto);
columns.ForeignKey(p => p.TipoTextoID,
(System.Collections.IEnumerable)ViewData["TiposTexto"],
"TipoTextoID",
"Designacao")
.Title("Tipo de texto").Width(150);
columns.Command(command =>
{
command.Edit();
command.Destroy();
}).Width(200);
})
.ToolBar(commands => commands.Create())
.Editable(editable => editable.Mode(GridEditMode.PopUp).TemplateName("Texto"))
.DataSource(dataSource => dataSource
.Ajax() //specify server type
.Model(model =>
{
model.Id(texto => texto.TextoID); // Specify the property which is the unique identifier of the model
model.Field(texto => texto.TextoID).Editable(false); // Make the ProductID property not editable
})
.Create(create => create.Action("CreateTexto", "BackOffice"))
.Read(read => read.Action("ReadTextos", "BackOffice"))
.Update(update => update.Action("UpdateTexto", "BackOffice"))
.Destroy(destroy => destroy.Action("DestroyTexto", "BackOffice")))
.Pageable() // Enable paging
.Sortable() // Enable sorting
.Selectable()
.Filterable()
.Scrollable()
)
<script type="text/javascript">
$(document).ready(function() {
$("form.k-edit-form").kendoValidator();
});
</script>
接下来，然后是模板：
@using System.Web.Mvc.Html;
@model KendoMVC.CostSimulatorService.Texto
Introduza o conteúdo que deseja
@Html.HiddenFor(model => model.TextoID)
<div id="divWrapper" style="width:99%; float:left;">
<div>
@Html.LabelFor(model => model.Titulo)
</div>
<div>
@Html.EditorFor(model => model.Titulo)
@Html.ValidationMessageFor(model => model.Titulo)
</div>
<div>
@Html.LabelFor(model => model.Corpo)
</div>
<div>
@(Html.Kendo().EditorFor(model => model.Corpo))
@Html.ValidationMessageFor(model => model.Corpo)
</div>
<div>
@Html.LabelFor(model => model.TipoTextoID)
</div>
<div>
@*@(Html.Kendo().DropDownListFor(model => model.TiposTexto))
@Html.ValidationMessageFor(model => model.TiposTexto)*@
@(Html.Kendo().DropDownListFor(m => m.TipoTextoID)
.Name("TiposTexto")
.DataTextField("Designacao")
.DataValueField("TipoTextoID")
.BindTo((System.Collections.IEnumerable)
ViewData["TiposTexto"]))
</div>
</div>
