How to add a custom control on TOP of another one
提问by Mathieu
I'm using a winForm. I have 2 custom controls that I want to add dynamically. The first one is added at the opening of the form. The second one is added when the user clicks a button. Nothing magic here. The problem is that when I instanciate and add the second control, instead of appearing on top of the other one, it appears under.
我正在使用 winForm。我有 2 个要动态添加的自定义控件。第一个是在表单打开时添加的。当用户单击按钮时添加第二个。这里没有什么魔法。问题是，当我实例化并添加第二个控件时，它没有出现在另一个控件的顶部，而是出现在下面。
There must be a way to add the control in a way that will make it fully visible (on top of the rest). Here is how I create the second control (same way as the first control). I tried using show/hide methods, but this won't change the stack order.
必须有一种方法来添加控件，使其完全可见（在其余部分之上）。这是我创建第二个控件的方法（与第一个控件相同）。我尝试使用显示/隐藏方法，但这不会改变堆栈顺序。
private void lbRappel_Click(object sender, EventArgs e)
{
NoteCallBack noteCallBack = new NoteCallBack("test");
this.Controls.Add(noteCallBack);
noteCallBack.Location = new Point(200, 250);
}
Thank you very much in advance for your help.
非常感谢您的帮助。

You could try the BringToFrontcontrol function:
您可以尝试BringToFront控制功能：
private void lbRappel_Click(object sender, EventArgs e)
{
NoteCallBack noteCallBack = new NoteCallBack("test");
this.Controls.Add(noteCallBack);
noteCallBack.Location = new Point(200, 250);
noteCallBack.BringToFront();
}

Can you create them at design time with the z-order you want, then only make them visible at runtime?
您能否在设计时使用所需的 z 顺序创建它们，然后仅在运行时使它们可见？
