这是一个完整的示例解决方案,用于演示我上面的建议。请注意,这一切都是在代码中完成的,并且只使用一个列,但也可以与设计器生成的控件(当然)和多个列一起使用。只需确保将所有控件设置为一行(例如,标签及其相应的输入控件)以Visible = false
使未使用的行正确折叠。
TableLayoutPanel tlp = new TableLayoutPanel();
tlp.RowStyles.Add(new RowStyle(SizeType.Absolute, 25));
tlp.RowStyles.Add(new RowStyle(SizeType.Absolute, 25));
tlp.RowStyles.Add(new RowStyle(SizeType.Absolute, 25));
tlp.RowStyles.Add(new RowStyle(SizeType.Absolute, 25));
tlp.RowStyles.Add(new RowStyle(SizeType.AutoSize));
tlp.RowStyles.Add(new RowStyle(SizeType.AutoSize));
tlp.RowStyles.Add(new RowStyle(SizeType.Absolute, 25));
TextBox b1 = new TextBox(); b1.Dock = DockStyle.Fill;
TextBox b2 = new TextBox(); b2.Dock = DockStyle.Fill;
TextBox b3 = new TextBox(); b3.Dock = DockStyle.Fill;
CheckBox special = new CheckBox(); special.Text = "Special?";
TextBox b4 = new TextBox(); b4.Dock = DockStyle.Fill; b4.Visible = false;
TextBox b5 = new TextBox(); b5.Dock = DockStyle.Fill; b5.Visible = false;
Button button = new Button(); button.Text = "Save";
special.CheckedChanged += new EventHandler((sender, args) => { b4.Visible = b5.Visible = special.Checked; });
tlp.Controls.Add(b1, 0, 0);
tlp.Controls.Add(b2, 0, 1);
tlp.Controls.Add(b3, 0, 2);
tlp.Controls.Add(special, 0, 3);
tlp.Controls.Add(b4, 0, 4);
tlp.Controls.Add(b5, 0, 5);

tlp.BringToFront();
