我有一个使用 Kendo UI 的 MVC4 .net 应用程序。当组合框和下拉列表都使用相同的功能进行读取时，我得到了 set jsonrequestbehavior 问题，但没有列表视图。我想填充一个下拉框。我错过了什么吗？相关代码：
cshtml（视图）的相关部分：
<script type="text/x-kendo-tmpl" id="propertiestemplate">
<div class="partnersss">
<h5>#:PartnerID#</h5>
<p>#:PartnerName#</p>
</div>
</script>
<div class="editor-field">
@(Html.Kendo().DropDownList()
.Name("partnerddl")
.HtmlAttributes(new { style = "width: 250px" })
.DataTextField("PartnerName")
.DataValueField("PartnerID")
.AutoBind(true)
.DataSource(source => {
source.Read(read =>
{
read.Action("GetPropertyPartners", "Property", new { onlyActive = true });
});
})
)
@(Html.Kendo().ComboBox()
.Name("partnercb")
.Placeholder("Select Partner...")
.DataTextField("PartnerName")
.DataValueField("PartnerID")
.AutoBind(true)
.Filter("contains")
.MinLength(3)
.DataSource(source => {
source.Read(read =>
{
read.Action("GetPropertyPartners", "Property", new { onlyActive = true });
}).ServerFiltering(true);
})
)
@(Html.Kendo().ListView<MyVegas.Rewards.Nucleus.Entities.PropertyPartnerView>()
.Name("partnerlv")
.TagName("div")
.ClientTemplateId("propertiestemplate")
.DataSource(ds => ds
.Read(read => read.Action("GetPropertyPartners", "Property", new { onlyActive = true }))
)
)
@Html.ValidationMessageFor(model => model.PartnerID)
</div>
控制器：
public JsonResult GetPropertyPartners([DataSourceRequest] DataSourceRequest dsRequest, bool onlyActive)
{
partners = property.GetPartnersForProperties(onlyActive);
var result = partners.ToDataSourceResult(dsRequest);
return Json(result);
}
结果协议主机 URL 正文缓存内容类型过程

28 500 HTTP localhost:2590 /Property/GetPropertyPartners?onlyActive=True 8,783 私有文本/html；charset=utf-8 iexplore:17452
29 200 HTTP localhost:2590 /Property/GetPropertyPartners?onlyActive=True 132 私有应用程序/json；字符集=utf-8 iexplore:17452
27 和 28 号返回这个 json（不正确）：
