我有master和详细信息kendo grid，当我插入/删除标题时一切正常，但是当我尝试在详细信息网格中插入多个记录时，create语句将循环显示所有插入的记录（新旧每次我尝试添加新记录时，当我尝试从详细信息表中删除记录时，视图将调用create方法而不是删除记录。
@(Html.Kendo().Grid(Model.ItemSuppliers)
.Name("CreateItem_gridSuppliers")
.Columns(columns =>
{
columns.Bound(p => p.ItemCode).Title(MyResources.GridItemCode).Width(100);

这是我的控制器
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult ItemOrigin_Create([DataSourceRequest] DataSourceRequest request, ItemOriginViewModel item, int itemSupplierID, string __cnv)
{
List<ItemOriginViewModel> itemOrigins = new List<ItemOriginViewModel>();
if (Session["ItemOrigin_" + __cnv + itemSupplierID] != null)
{
itemOrigins = (List<ItemOriginViewModel>)Session["ItemOrigin_" + __cnv + itemSupplierID];
if (item.UID == null)
{
item.UID = Guid.NewGuid().ToString();
item.ItemSuppliersID = itemSupplierID;
itemOrigins.Add(item);
}
else
{
int index = itemOrigins.FindIndex(x => x.UID == item.UID);
itemOrigins[index] = item;
}
}
else
{
item.UID = Guid.NewGuid().ToString();
item.ItemSuppliersID = itemSupplierID;
itemOrigins.Add(item);
}
Session["ItemOrigin_" + __cnv + itemSupplierID] = itemOrigins;
return Json(itemOrigins.ToDataSourceResult(request));
}
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult ItemOrigin_Delete([DataSourceRequest] DataSourceRequest request, ItemOriginViewModel item, string __cnv)
{
List<ItemOriginViewModel> itemOrigins = (List<ItemOriginViewModel>)Session["ItemOrigin_" + __cnv + item.ItemSuppliersID];
int index = itemOrigins.FindIndex(x => x.ItemOriginID == item.ItemOriginID);
itemOrigins.RemoveAt(index);
Session["ItemOrigin_" + __cnv + item.ItemSuppliersID] = itemOrigins;
var result = itemOrigins;
return Json(result.ToDataSourceResult(request));
}
有任何建议请解决这个问题??
答案 0 :(得分：0)
Kendo DataSource将尝试发送标记为“新”或“脏”的项目。 “新建”仅表示商品ID（看起来您的ID列为ItemSuppliersID）为undefined或0。只要没有设置ID，它就会继续重新发送这些项目。
通常，您的控制器应该返回刚插入的项目，但ID现在设置为新值。然后，Kendo会将响应中的ID复制到客户端上的对象。由于随后设置了ID，该项目将不再标记为“新”，并将停止发送到服务器。
换句话说，如果你发帖：
{
"ItemSuppliersID": 0,
"ItemCode": "ABC"
}
然后控制器应该返回：
{
"ItemSuppliersID": 123, // <-- ID field is now set
"ItemCode": "ABC"
}
