剑道网格分组列 - 类型错误:无法读取未定义的属性“长度”
Kendo Grid Grouping on column - TypeError: Cannot read property 'length' of undefined
我在剑道网格中对数据进行分组时遇到问题。
我拖动要用于组的列，我总是收到以下错误。
TypeError: Cannot read property 'length' of undefined
我试图找到触发错误的位置，但没有运气。
返回来自服务器的分组数据。
非常感谢您的任何建议。

由于剑道论坛上提到的冲突和问题，您正在收到异常 这里 和 这里
请避免使用
kendo.web.min.js
kendo.dataviz.min.js
使用它们并使用 kendo.all.min.js 在对 Kendo DataSoruce 执行读取操作时将返回此类异常.js因为 kendo.web.min 和 kendo.dataviz.min.js共享公共代码（kendo.core.js、kendo.data.js 等），使用它们会产生冲突，并在读取函数返回成功时返回数据源异常。
