MDI家长表格.子窗体再次被调用时不会出现在最大化状态 [英] MDI Parent Form. Child Forms when called again do not appear in Maximized State

问题描述

我已在我的MDIParent1.cs文件中添加了以下内容

I have added follwing in my MDIParent1.cs file

public static Form1 frm1 = new Form1();
        public static Form2 frm2 = new Form2();
        public static Form3 frm3 = new Form3();

private void MDIParent1_Load(object sender, EventArgs e)
        {

            frm1.MdiParent = this;
            frm2.MdiParent = this;
            frm3.MdiParent = this;
            frm1.Show();
        }

然后，将所有三种形式的WindowsState属性都设置为Maximized.

在Form1.cs

Then I set the WindowsState property of all three forms to Maximized.

in Form1.cs

private void button1_Click(object sender, EventArgs e)
       {
                      this.Hide();
           MDIParent1.frm2.Show();
       }

在Form2.cs中

in Form2.cs

private void button1_Click(object sender, EventArgs e)
        {
            this.Hide();
            MDIParent1.frm3.Show();

        }

在Form3.cs中

in Form3.cs

private void button1_Click(object sender, EventArgs e)
        {
            MDIParent1.frm1.Show();
            this.Hide();
        }

当我单击Form1、2的按钮时，我没有问题.一次.
但是当我按下Form3的Button时，我得到的Form1不是最大化的形式，而是还原的形式.
我希望那个form1以最大化状态出现.
我该怎么办?
请帮助

I don''t problem when I click on buttons of Form1, 2 resp. once.
but wen I press Button of Form3 I get Form1 not in maximized form but in restored form.
I want that form1 to appear in Maximized state.
Wat should I do?
Please Help

推荐答案

我有替代解决方案

I got an alternative solution

frm1.Dock = DockStyle.Fill;
            frm2.Dock = DockStyle.Fill;
            frm3.Dock = DockStyle.Fill;

但我仍然想知道为什么第二次显示表单时，表单却没有最大化显示

but still I wanna know why the forms do not appear maximized when the second time they are showed
