Question

我创建了一个使灯箱效果生效的表单。在创建此灯箱表单后，我创建了另一个表单。

//Execute from parent form
Form f = new Form();
f.ShowInTaskbar = false;
f.BackColor = Color.Black;
f.Size = this.Size;
f.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
f.StartPosition = FormStartPosition.CenterParent;
f.Opacity = 0.6;
f.ShowDialog(); // Open Modal window
notificationSize nds = new notificationSize(); 
nds.Show(); // Open another form on Modal Dialog

创建灯箱表单后，它不会显示另一个表单nds。只需showind the lightbox模态对话框。

如何在模态表单上显示表单？

Answer 1

展示您的孩子＆＃34;将TopLevel设置为false：

Form f = new Form();
f.ShowInTaskbar = false;
f.BackColor = Color.Black;
f.Size = this.Size;
f.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
f.StartPosition = FormStartPosition.CenterParent;
f.Opacity = 0.6;

notificationSize nds = new notificationSize();
nds.TopLevel = false;
nds.FormBorderStyle = ... // you may want to set this to none
nds.Dock = ... // you may want to set this to fill
f.Controls.Add(nds);
nds.Show(); // Open another form on Modal Dialog

f.ShowDialog(); // Open Modal window

嗯，我不太明白这个目的是什么，但是这样可以解决问题：

        var f = new Form();
        f.IsMdiContainer = true;
        f.ShowInTaskbar = false;
        f.BackColor = Color.Black;
        f.Size = this.Size;
        f.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
        f.StartPosition = FormStartPosition.CenterParent;
        f.Opacity = 0.6;
        var nds = new notificationSize();
        nds.Show();
        nds.MdiParent = f;
        f.ShowDialog(); // Open Modal window

从父表单打开的模式表单打开表单
