设置未知属性：yii\grid\GridView:：export

我是yii2的新手，正在学习。我已经在我的项目中安装了yii2导出菜单，然后它给出了错误=Class'kartik\dialog\dialog'未找到 然后我安装了yii2拨号程序，现在它也给出了错误

Setting unknown property: yii\grid\GridView::export

有人能帮忙解决吗

错误是

Unknown Property – yii\base\UnknownPropertyException

                return;
            }
        }

        if (method_exists($this, 'get' . $name)) {
            throw new InvalidCallException('Setting read-only property: ' . get_class($this) . '::' . $name);
        }

        throw new UnknownPropertyException('Setting unknown property: ' . get_class($this) . '::' . $name);
    }

     *  - a property of a behavior: return whether the property is set
     *  - return `false` for non existing properties

要使用yii2导出菜单小部件，所需的小部件为=> 1积金局 2动态网格 3对话

然后只有我们可以使用导出菜单小部件

您应该显示更多代码，而不仅仅是错误。正如您所看到的，它只说明您正在运行的

GridView

没有属性

export

。可能您已安装了不同的GridView小部件，但您仍在调用原始的Yi2 GridView，而不是调用具有此

导出

参数的新GridView。是的，您是对的。。我通过安装yii2dynagrid小部件修复了它
