当您建立页面的执行个体时，无论是否是目前作用中表单，都会建立该页面上所有表单的执行个体。

When you create an instance of a page, instances of all forms on that page are created, regardless of the current active form.

反而表单会隐藏并可再次显示，不需建立对话方块的新执行个体。

Instead the form is hidden and can be shown again without creating a new instance of the dialog box.

因此，您无法建立这个控制项集合的多个执行个体并将它们与作用中的表单互换，以提供不同的控制项配置。

As a result, you cannot create multiple instances of this control collection and interchange them with an active form to provide different control layouts.
