我正在尝试使用下拉菜单和/或文本框来编辑可扩展网格的父行的列过滤器。我也隐藏了实际的网格过滤器，因为我只希望用户能够从下拉列表/文本框中进行过滤。
我通过将控件的ng-model设置为$ctrl.gridOptions.grid.columns[0].filters[0].term来在常规ui网格上工作，这完全符合我的期望。但是，当我将其更改为可扩展网格时，它将不再起作用。如果我尝试在函数（称为updateFilter）中手动设置术语，Chrome会显示此错误：
TypeError: Cannot read property 'grid' of undefined

有人知道如何通过可扩展网格实现此功能吗？
