Telerik ASP.NET MVC Grid 在弹出模式下编辑时出现奇怪的 jscript 错误
我有一个网格，我试图在弹出模式下编辑它。弹出窗口打开正常。我在弹出窗口中又放置了两个网格。我通过 javascript ajax 调用加载它们。弹出的这两个网格也可以很好地填充。单击弹出窗口的提交（这是默认的复选标记图标）后，我收到此 Jscript 错误 “data.CancelledAMA.AgreementID 为空或不是对象”
其中 CancelledAMA 是我的模型 (ReplacementCombo) 中的自定义对象，我将其绑定到原始网格（不是弹出窗口中的 2 个网格）。并且 ContractId 是 CancelledAMA 对象中的一个 int
我已经在原始网格中尝试了 .DefaultDataItem(new ReplacementCombo()) ，以便模型对象填充默认值，并在 ReplacementCombo 模型类中创建构造函数对象。但没有任何作用。
I have a Grid, which I am trying to Edit in Pop Up mode. The pop up opens fine. I have placed two more grids within the pop up window. I load them through javascript ajax calls. These 2 grids on pop up also get populated just fine. Once I click on the submit for the pop up window (which is the default checkmark icon), I get this Jscript error
"data.CancelledAMA.AgreementID is null or not an object"
Where CancelledAMA is a custom object in my model (ReplacementCombo) that I bind to the original grid (not the 2 grids within the pop up window). And AgreementId is an int within the CancelledAMA object
I have tried the .DefaultDataItem(new ReplacementCombo()) in the original grid so that the model object gets populated with default values and created a constructor object too in the ReplacementCombo model class. But nothing works.

各位，
我很自豪地说，经过几个小时的痛苦，我发现了问题并解决了它！
吸取的教训，在 Telerik MVC 网格上，您无法从网格模型的嵌套对象中获取 DataKey。我的原始网格的数据键为 CancelledAMA.AgreementID，并且 CancelledAMA 是绑定到原始网格的模型 (ReplacementCombo) 内的嵌套对象。您只能拥有模型对象顶层属性的数据键，而不是嵌套对象的属性。
谢谢。
People,
I feel proud saying that after hours of pain, I have found the issue and resolved it!
Lesson learnt, on the Telerik MVC Grid you cannot have the DataKey from a nested object of the grid model. My original grid had the datakey as CancelledAMA.AgreementID and CancelledAMA is a nested object within the Model (ReplacementCombo) bound to the original Grid. You can only have a datakey to a property on the top level of the model object not properties of nested objects.
Thanks.
