Answer 1

Align a control in parent vertically:

InsidePanel.Location = new Point(
    0, (OutsidePanel.Height - InsidePanel.Height) / 2
);

Align a control in parent horizontally:

InsidePanel.Location = new Point(
    (OutsidePanel.Width - InsidePanel.Width) / 2, 0
);

If you do have form resizing, you will need to make sure this is added to you resize event handler to make sure the controls stay centered.

You can use a TableLayoutPanel control.

1. Drag a TableLayoutPanel onto your form
2. Set the Dock property to Fill
3. Remove one of the columns from the Columns collection because by default you will get 2 columns.
4. Add one more Row to your panel because by default you will get 2.

Then:

1. Put the textbox into the second row.
2. Set the Dock property to Fill

Set the sizes for the rows for the TableLayoutPanel as shown in the following screenshot:
