打开新的“子表单"内部“来自……的宽恕"来自已经打开的子窗体. [英] Open new "child form" inside "parrent from" from already open child form.

问题描述

我有三种形式

MainForm
LoginForm
ControlPanelForm

Na主要表单是MDI容器，在加载时，我在MDI内启动Login表单，在用户输入信息并按下按钮后，我需要在MDI容器内打开控制面板"表单.

这是我尝试的方法:

Hi, I have three forms

MainForm
LoginForm
ControlPanelForm

Na Main form is MDI container, on load I start Login form inside MDI, after user enter information and press button I need to open Control Panel form but inside MDI container.

This is what I try:

ControlPanelForm OpenNew = new ControlPanelForm();
//OpenNew.MdiParent = this;
OpenNew.MdiParent = MainForm.MainForm;
OpenNew.Show();

我不知道如何引用mainForm

I dont know how to reference to mainForm

推荐答案

这是什么.MdiParent?我认为这将是登录"表单(对吗?)，并且MDI应该相同..

What about this.MdiParent? I think this would be the Login form (right?) and the MDI should be the same..

您是我的英雄.
非常感谢.

You are my hero.
