WinForms文本框中的按钮(Button inside a winforms textbox)

 winforms文本框是否有可以在框的结尾处生成嵌入式按钮的属性？ 
 
 就像Chrome地址框上的收藏夹按钮一样： 
 
 
 我在一些Excel表格中也看到了类似下面的内容：

 我跟着Hans Passant的答案加入了一个点击事件处理程序，它似乎可以正常工作： 
 
    protected override void OnLoad(EventArgs e) {
        var btn = new Button();
        btn.Size = new Size(25, textBoxFolder.ClientSize.Height + 2);
        btn.Location = new Point(textBoxFolder.ClientSize.Width - btn.Width, -1);
        btn.Cursor = Cursors.Default;
        btn.Image = Properties.Resources.arrow_diagright;
        btn.Click += btn_Click;     
        textBoxFolder.Controls.Add(btn);
        // Send EM_SETMARGINS to prevent text from disappearing underneath the button
        SendMessage(textBoxFolder.Handle, 0xd3, (IntPtr)2, (IntPtr)(btn.Width << 16));
        base.OnLoad(e);
    }

    [System.Runtime.InteropServices.DllImport("user32.dll")]
    private static extern IntPtr SendMessage(IntPtr hWnd, int msg, IntPtr wp, IntPtr lp);

    private void btn_Click(object sender, EventArgs e) {
        MessageBox.Show("hello world");
    }

Do winforms textboxes have any properties that make an embedded button, at the end of the box, possible?
 
Something like the favorites button on the Chrome address box:
 
 
I've also seen something like the following in some Excel forms:
 
 
 
EDIT
 
I've followed Hans Passant's answer with the addition of a click event handler and it seem to work ok:
 
    protected override void OnLoad(EventArgs e) {
        var btn = new Button();
        btn.Size = new Size(25, textBoxFolder.ClientSize.Height + 2);
        btn.Location = new Point(textBoxFolder.ClientSize.Width - btn.Width, -1);
        btn.Cursor = Cursors.Default;
        btn.Image = Properties.Resources.arrow_diagright;
        btn.Click += btn_Click;     
        textBoxFolder.Controls.Add(btn);
        // Send EM_SETMARGINS to prevent text from disappearing underneath the button
        SendMessage(textBoxFolder.Handle, 0xd3, (IntPtr)2, (IntPtr)(btn.Width << 16));
        base.OnLoad(e);
    }

    [System.Runtime.InteropServices.DllImport("user32.dll")]
    private static extern IntPtr SendMessage(IntPtr hWnd, int msg, IntPtr wp, IntPtr lp);

    private void btn_Click(object sender, EventArgs e) {
        MessageBox.Show("hello world");
    }
