添加表格到用户控件 - 这可能吗？ [英] Add Form to a UserControl - is this possible?

问题描述

一般情况下，控制被添加到形式。但我需要做一个相反的事 - 添加一个窗体实例容器的用户控件

Normally, controls are being added to forms. But I need to do an opposite thing - add a Form instance to container user control.

这背后的原因是，我需要嵌入一个第三方应用到我自己。形式转换为用户控制是不可行的，由于复杂性。

The reason behind this is that I need to embed a third-party application into my own. Converting the form to a user control is not feasible due to complexity.

推荐答案

这是可以通过表单的顶层属性设置为false。其中把它变成一个子窗口，从用户控件几乎没有区别。下面是与所需的code示例用户控件：

This is possible by setting the form's TopLevel property to false. Which turns it into a child window, almost indistinguishable from a UserControl. Here's a sample user control with the required code:

public partial class UserControl1 : UserControl {
    public UserControl1() {
        InitializeComponent();
    }
    public void EmbedForm(Form frm) {
        frm.TopLevel = false;
        frm.FormBorderStyle = FormBorderStyle.None;
        frm.Visible = true;
        frm.Dock = DockStyle.Fill;   // optional
        this.Controls.Add(frm);
    }
}
