如何在运行时在C#.net中从MDI父级加载的用户控件中找到MDI父级的活动子窗体? [英] How to find the active child form of MDI parent from User control which is loaded in MDI Parent at runtime in C#.net?

问题描述

IDE: Microsoft Visual Studio

平台: C#.net

我正在尝试从运行时加载的用户控件中获取MDI父级的活动MDI子级的实例.

Hi, I am trying to get the instance of active MDI child of MDI parent from user control which is loaded at runtime.

推荐答案

在MDI父表单的代码中的任何位置，您都可以使用:

From anywhere within your MDI parent form's code, you can use:

Form activeChild = this.ActiveMdiChild;

这将为您提供当前集中(激活)的子表单的表单实例.每次打开新的子窗体时，或者当用户单击(聚焦)另一个子窗体时，它都会改变.

That will give you the form instance of the currently focused (activated) child form. It will change each time a new child form is opened, or when the user clicks (focuses) a different child.
