Windows窗体，对象出现在其他项目的前面？

Question

当我在我的表单中添加氪项时，它们会显示在其他项目的顶部，我怎么能这样做以便我可以在其他项目后面添加一些内容？

Answer 1

假设您正在使用Winform设计器，您可以右键单击一个控件并从上下文菜单中选择“Bring to Front”或“Send to Back”来更改控件的“z-order”。

Answer 2

The order of control appearing inside their parrent container is controlled by Z-Index.

Right click control in the designer. Select "Bring ro front" from the context menu.

If you doing it programmtiacly. All control in winforms environment have two methods : BringToFront() and SendToBack(). You can call it to setup z-index of controls.

If you want to specify Z-Index explicitly you may use this workaround:

public static class ControlExtension
{

    public static void SetControlZIndex(this Control ctrl, int z)
    {
       ctrl.Parent.Controls.SetChildIndex(ctrl, z);
    }
}

Usage:

button1.SetControlZIndex(10);
