Question

使用Powershell，我有一个包含多个标签的表单。

在第三个选项卡中，我创建了一个从Windows注册表中选取的数字数组，我将其放入ComboBox中。然后我根据ComboBox自动根据注册表值名称制作几个CheckBox。

我的问题是，当我更改ComboBox的文本时，我无法刷新/更新CheckBox。我尝试了“.Refresh（）”，如下面和其他东西，但它不起作用。

以下是我的注册表项：

我不认为你订阅了正确的活动。

你看过SelectedIndexChanged吗？

当选择发生变化时会触发，然后您可以查看ComboBox的Index属性以确定哪个项目已更改。索引为负数表示组合框中没有项目被选中。

点击事件与组合框中的选定项目无关。

Powershell从ComboBox刷新CheckBox数组
