Answer 1

你把这个panel1放到Controls去试试
Controls.Add(panel1);

Answer 2

  楼上的朋友，可能领悟错了，panel1的变化不用管，我就想，不管pannel怎么变化，button紧贴pannel的TOP边框，大小不变，而datagridview填充余下的下方全部空间

Answer 3

datagridviewr.Anchor = ((System.Windows.Forms.AnchorStyles)((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom)
                        | System.Windows.Forms.AnchorStyles.Left)
                        | System.Windows.Forms.AnchorStyles.Right)));

Answer 4

datagridview要向四个方向伸展。
