利用fineUi构建分页表格时候，报错：

[NullReferenceException: 未将对象引用设置到对象的实例。]   FineUI.Grid.AddClientSuitableFormatValues(Nullable`1& renderAsJArray, JObject jo, String name, Object[] values) +34   FineUI.Grid.get_F_Rows() +254[TargetInvocationException: 调用的目标发生了异常。]   System.RuntimeMethodHandle.InvokeMethod(Object target, Object[] arguments, Signature sig, Boolean constructor) +0   System.Reflection.RuntimeMethodInfo.UnsafeInvokeInternal(Object obj, Object[] parameters, Object[] arguments) +87   System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture) +101   System.Reflection.RuntimePropertyInfo.GetValue(Object obj, BindingFlags invokeAttr, Binder binder, Object[] index, CultureInfo culture) +61   System.Reflection.RuntimePropertyInfo.GetValue(Object obj, Object[] index) +21   FineUI.ControlBase.GetPropertyJSONValue(String prop) +73   FineUI.FState.CalculateModifiedProperties() +137   FineUI.ControlBase.OnPreRender(EventArgs e) +101   System.Web.UI.Control.PreRenderRecursiveInternal() +88   System.Web.UI.Control.PreRenderRecursiveInternal() +160   System.Web.UI.Control.PreRenderRecursiveInternal() +160   System.Web.UI.Control.PreRenderRecursiveInternal() +160   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +883

我这个原因是Grid控件没有行关键值，解决方案：添加下图矩形框内容

这里写图片描述
