如何在MDIParent控件的顶部显示MDIChild表单

问题描述

我有一个带有许多ChildForms的MDI-Parent表单，当我想在我的Parent表单上添加一个控件时，Child表单出现在该控件下，例如，我想在MDIParent表单上添加一个groupbox和PictureBox，但是当我称它为出现在这些控件下的子窗体.

I have a MDI-Parent Form with many ChildForms, when I want to add a control on my Parent form, Child form appears under the control, For example I want to add a groupbox and a PictureBox on MDIParent Form, but when I call the Child Form it appears Under these controls.

推荐答案

private void MainModule_MdiChildActivate(object sender, EventArgs e)
{
    foreach (Form frmChild in this.MdiChildren)
    {
        if (frmChild.Visible == true)
        {
            if (frmChild.Name == "YourFormName")
            {
                mnuMainMenu.Dispose();
            }
        }
        else
        {
            this.mnuMainMenu = new System.Windows.Forms.MainMenu(this.components);
            this.Menu = mnuMainMenu;
            MainModule_Load(sender, e);
        }
    }
}

激活子窗体时，这将处理MDIParent菜单，当您关闭子窗体时，将再次出现MDIParent菜单.

希望对您有帮助.

This Will dispose your MDIParent menu when child form is activated and when you close the child form then MDIParent Menu will appear again.

Hope this will help you.
