There is some mixing up going on in most of times between the terms "caret" and "cursor". Cursor is the mouse cursor, caret is the vertical blinking bar inside the textbox that indicates the insertion point.
You can control caret position (and selection) by
Example if you want move caret before 3th character set
SelectionStart = 2
SelectionLength = 0

If you mean the mouse cursor and the caret at the same time, then you can use a code like:

// save current cursor position and selection 
        int start = textBox.SelectionStart;
        int length = textBox.SelectionLength;

        Point point = new Point();
        User32.GetCaretPos(out point);

        // update text
        textBox.Text = value;

        // restore cursor position and selection
        textBox.Select(start, length);
        User32.SetCaretPos(point.X, point.Y);
