我尝试过$.ajaxStart(function(){}),但它并没有取代它,而是附加了.
我用两个表创建了一个测试SQL Server数据库:WorkItem和WorkItemNote。它们之间有一个外键,因此一个WorkItem可以具有许多WorkItemNote记录。我试图在Kendo网格中显示WorkItems。该Action返回Json,但网格中未显示任何内容。
如果我仅使用要显示的属性创建一个匿名对象,它将起作用。这表示具有关系(WorkItemNote)的实体(WorkItem)无法显示在Kendo网格中。
有没有办法解决?
我的网格:
<div>
@(Html.Kendo().Grid<TryToLoadGrid.Models.WorkItem>()
.Name("grid")
.HtmlAttributes(new { style = "height:380px;" } )
.Sortable()
.Pageable()
.DataSource(dataSource => dataSource.Ajax().Read(read => read.Action("GetActiveWorkItems", "Home")))
.Columns(columns =>
{
columns.Bound(workItem => workItem.Title);
columns.Bound(workItem => workItem.Description);
}
)
)
</div>

我的动作代码是:
public ActionResult GetActiveWorkItems([DataSourceRequest]DataSourceRequest request)
{
using (TaskManagerContext context = new TaskManagerContext())
{
IQueryable<WorkItem> list = context.WorkItems.Where(x => x.IsActive == true);
DataSourceResult result = list.ToDataSourceResult(request);
return Json(result);
}
}

从“动作”中可以看出,我对网格的WorkItemNotes甚至都不感兴趣。
为了证明这是由于这种关系造成的,我创建了第二个Action,它可以正常工作并显示数据:
public ActionResult GetActiveWorkItems2([DataSourceRequest]DataSourceRequest request)
{
using (TaskManagerContext context = new TaskManagerContext())
