Question

我在ExtJS 6.5中有一个带有更多组合的网格面板。当我从第一列的组合中选择一个值时，我想为最后一列和同一行中的组合设置隐藏或禁用属性。我试过但它适用于最后一列中的所有组合，而不仅仅是来自同一行的组合。 Here是小提琴。谢谢！

Ext.create('Ext.grid.Panel', {
        title: 'Simpsons',
        store: Ext.data.StoreManager.lookup('simpsonsStore'),
        viewModel: {
            data: {

                var iconCls = Ext.getStore('hungryStore').findRecord('value', v).get('iconCls');

您需要使用beforeedit插件的cellediting事件。

在 FIDDLE 中，我使用您的代码创建了一个演示并进行了一些更改。我希望这有助于/指导您实现您的要求。

如何绑定Ext.grid.Panel中的两个组合框？
