如何在一个Form上放上另一个Form(不使用Mdi)

Question

什么意思？
嵌套在Form中？

Answer 1

可以放在Panel里面,设定窗体2的父控件是Panel就可以了

Answer 2

有两个方式可以来实现:
1:
Form f = new Form();
f.TopLevel = false;
this.Controls.Add(f);
f.Visible = true;2:
Form f = new Form();
f.FormBorderStyle = FormBorderStyle.None;
this.Controls.Add(f);
f.Visible = true;

Answer 3

如下向Panel添加一个带标题栏的窗体.
Form f=new Form();
f.TopLevel=false;
f.Visible=true;
this.Panel.Controls.Add(f);如下向Panel添加一个不带标题栏的窗体.
Form f=new Form();
f.FormBorderStyle = FormBorderStyle.None;
f.Visible=true;
this.Panel.Controls.Add(f);

Answer 4

参考这个代码
        //子窗体唯一
        public static bool m_HaveChildForm = false;
        public static Form m_UniqueChildForm = null;
        //Panel中窗体object对象
        private object typForm = null;
        private Form childForm = null;#region 加载窗体
        /// <summary>
        /// 根据namespace动态创建窗体
        /// </summary>
        /// <param name="childFormHandleName">类的命名空间+类的名称</param>
        private void LoadChildForm(string childFormHandleName)
        {
            typForm = null;
            //动态反射一个窗体对象
            typForm = Assembly.Load("SISP.ClientSimple").CreateInstance(childFormHandleName);            
            if (typForm != null)
            {
                if (!m_HaveChildForm)
                {
                    try
                    {
                        //动态显示窗体
                        ShowChildForm(typForm);
                    }
                    catch
                    {
                        //窗体加载失败!
                        MessageBox.Show("窗体加载失败!");
                    }                }
                else
                {
                    m_UniqueChildForm.Close();
                    m_UniqueChildForm.Dispose();
                    m_UniqueChildForm = null;                    m_HaveChildForm = false;                    try
                    {
                        //动态显示窗体
                        ShowChildForm(typForm);                    }
                    catch
                    {
                        //窗体加载失败!
                        MessageBox.Show("窗体加载失败!");
                    }
                }
            }
        }/// <summary>
        /// 根据object对象动态显示窗体
        /// </summary>
        /// <param name="handleForm">objectform's handle</param>
        private void ShowChildForm(object handleForm)
        {
            try
            {
                childForm = (Form)handleForm;                //设置窗体级别
                childForm.TopLevel = false;                //在Panel中加载窗体对象
                this.spCon_Main.Panel2.Controls.Add(childForm);                //让窗体布满整个Panel控件中
                childForm.Dock = DockStyle.Fill;                //根据整体主窗体样式变化子窗体的样式
                //FormStyleCustom(childForm);                //显示子窗体
                childForm.Show();                m_HaveChildForm = true;
                m_UniqueChildForm = childForm;
            }
            catch
            {
                //窗体加载失败!
                MessageBox.Show("窗体加载失败!");
            }        }
