找回隐藏的表单从另一种形式 [英] get back hidden FORM from another FORM

问题描述

我有两种形式 Form1中和窗体2

我在 button_Click 打开窗体2 从 Form1中

Form2 obj2 = new Form2();
this.Visible = false;
obj2.Show();

那么我想回去 Form1中可见（上布置窗体2 ）的控制上，我留下了相同的状态......

then I want to get back Form1 Visible (on disposing Form2) in same states of Controls on which I left.....

推荐答案

您窗体2 不知道 Form1中任何。这将需要一个参考吧（你可以做到这一点通过增加一个表格在窗体2 type属性，并指定 Form1中将其施工后）：

Your Form2 doesn't know anything about Form1. It will need a reference to it (you can do that by adding a Form type property on Form2 and assign Form1 to it after construction):

//In Form2
public Form RefToForm1 { get; set;}

//In Form1
Form2 obj2 = new Form2();
obj2.RefToForm1 = this;
this.Visible = false;
obj2.Show();

//In Form2, where you need to show Form1:
this.RefToForm1.Show();
