经过这么多个小时的点击和尝试,我终于解决了。因此,我将其发布在这里,以节省其他人遇到类似问题的时间:
我在主网格中添加了一个
DetailExpand
事件。并删除了 Change
上的 dataSource
事件。
@(Html.Kendo()
.Grid<ProjectName.DataModels.Models.Customer>()
.Name("CustomerGrid")
.Columns(columns =>
{
columns.Bound(e => e.CustomerId);
columns.Bound(e => e.SomeCustomerColumn);
})
.ClientDetailTemplateId("OrderDetails")
.AutoBind(false) // Don't load the data yet because I'll need to supply parameters for the fetch
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(20)
.Model(model => model.Id("CustomerId", typeof(string)))
.Read(read => read.Action("GetCustomersAsync", "Customer").Data("passArguments"))
)
.Events(events => events.DataBound("dataBound").DetailExpand("onExpand"))
)
现在,每次我们在父网格中展开一行时,都会调用名为
onExpand
的回调函数。我现在将在此处设置子网格的 dataSource
。
// Passing e is also important here because if you don't, this callback gets called
// for every row in the main grid (even when you don't expand them!)
function onExpand(e) {
var customerId = e.sender.dataItem(e.masterRow).CustomerId;
var orders = e.sender.dataItem(e.masterRow).Orders;
//Initialize the child grid as well
var childGridName = "#" + "OrderDetails_" + customerId;
var childGrid = $(childGridName).data("kendoGrid");
if (childGrid !== undefined) {
childGrid.dataSource.data(orders);
}
}
function dataBound() {
this.expandRow(this.tbody.find("tr.k-master-row").first());
}
我使用
e.sender.dataItem(e.masterRow).PROPERTYNAME
从主行访问我需要的属性。
现在完美无缺!
