如何彻底带来正面一个WinForm的时候被激活 [英] How to completely bring to front a WinForm when activated

问题描述

我有两个对话框， FORMA 和 FormB 。我用下面的code显示（无模式） FormB 。在code是点击一个按钮，从 FORMA 。

I have two dialogs, FormA and FormB. I use the following code to show (modeless) FormB. The code is a button click executed from FormA.

    private void button_Click(object sender, EventArgs e)
    {
        FormB fB = new FormB();
        fB.Show(this); // FormA is the owner of FormB
    }

现在的问题是，当 FormB 超过 FORMA 在屏幕上，如果我点击 FORMA ，它被激活，但没有引起面前。其实FormB总是超过FORMA

The problem is that when FormB is over FormA on the screen, if I click FormA, it is activated, but not brought to front. Actually FormB is always over FormA

你知道为什么，以及如何改变这种行为，不删除所有者的财产？

Do you know why, and how to change this behavior, without remove the owner property?

注意：这是我的问题简单化。在真正的问题，FORMA是一个Windows资源管理器窗口，并FormB是一个管理的WinForm的，但行为是一样的。如果我不通过IWin32Window到显示（），它工作正常，但如果我关闭A，B不闭合，它不响应事件（请参阅下面的<一href="http://stackoverflow.com/questions/7000532/close-child-dialogs-when-closing-the-parent">entry).

NOTE: This is a simplification of my problem. In the real problem, FormA is a Windows Explorer window, and FormB is a managed WinForm, but the behavior is the same. If I do not pass the IWin32Window to Show(), it works fine, but If I close A, B is not closed and it does not respond to events (see the following entry).

推荐答案

您不能这样做不删除所有者属性。

You cant do this without removing the owner property.

从技术文档： 拥有形式也永远不会显示背后的所有者的形式。

From Documentation: Owned forms are also never displayed behind their owner form.

有关您的具体问题，你为什么不听的关闭事件，然后明确地关闭自己的形式？

For your specific problem why do you not listen for the Close Event and then explicitly close your own form?
