c# - 非顶级表单的 StartPosition

Question

子窗体的起始位置即使我这样手动编程也无法设置:

f = new Home_Button_Forms.Home_Mandated_Organization();
f.TopLevel = false;
f.Parent = panel1;
f.WindowState = System.Windows.Forms.FormWindowState.Normal;
f.StartPosition = FormStartPosition.CenterScreen;
f.Show();

它仍然出现在 panel1(Parent Form)的左上角。

Answer 1

当你想将一个非顶层的表单移动到它的容器面板的中心时，你可以手动设置表单的Location:

var f = new Form2();
f.TopLevel = false;
f.Parent = this.panel1;
f.StartPosition = FormStartPosition.Manual;
f.Location = new Point((this.panel1.Width - f.Width) / 2, 
                       (this.panel1.Height - f.Height) / 2);
f.Show();
