c# - 当嵌入其中的表单关闭时如何关闭选项卡？

Question

我的表单嵌入在标签页的顶部。当我关闭标签页顶部的表单时，如何也关闭标签页？

当我将表单放在标签页上时的代码更像这样：

client c = new client(car_name, owner);   //here client is another winform class
c.TopLevel = false;
c.Visible = true;
c.BackColor = Color.Ivory;
c.FormBorderStyle = FormBorderStyle.None;
c.Dock = DockStyle.Fill;
tabControl1.TabPages[tab_index].Controls.Add(c);

Answer 1

使用 FormClosing 事件：

private void ClientForm_FormClosing(object sender, FormClosedEventArgs e)
    {
      ((TabControl)((TabPage)this.Parent).Parent).TabPages.Remove((TabPage)this.Parent);
    }
