Use the beforeedit listener and context.record to get the desired row
使用 beforeedit 侦听器和 context.record 获取所需的行
this.editing = Ext.create('Ext.grid.plugin.CellEditing', {
clicksToEdit: 1,
listeners: {
beforeedit: function (obj) {
var MyColumnValue = obj.context.record.get('YourColumnName');
// or maybe to clear the value of this cell
obj.context.record.set('YourColumnName', null);
}
}
});
