c# winform 用listview做導航界面，控件上下移動後 順序不對？

private void button1_Click(object sender, EventArgs e)

{

listView1.Dock = DockStyle.None;

button1.Dock = DockStyle.Top;

button2.Dock = DockStyle.Bottom;

button3.Dock = DockStyle.Bottom;

button4.Dock = DockStyle.Bottom;

button5.Dock = DockStyle.Bottom;

button6.Dock = DockStyle.Bottom;

button7.Dock = DockStyle.Bottom;

button8.Dock .SendToBack();

button8.Dock = DockStyle.Bottom;

listView1.BringToFront();

listView1.Dock = DockStyle.Bottom;

listView1.Clear();

......

}

button2按鈕：

private void button2_Click(object sender, EventArgs e)

{

listView1.Dock = DockStyle.None;

button2.Dock = DockStyle.Top;

button1.SendToBack();

button1.Dock = DockStyle.Top;

button2.Dock = DockStyle.Bottom;

button3.Dock = DockStyle.Bottom;

button4.Dock = DockStyle.Bottom;

button5.Dock = DockStyle.Bottom;

button6.Dock = DockStyle.Bottom;

button7.Dock = DockStyle.Bottom;

button8.Dock = DockStyle.Bottom;

listView1.BringToFront();

listView1.Dock = DockStyle.Bottom;

listView1.Clear();

listView1.Items.Add("患者治療排班", "患者治療排班", 3);

}

其他按鈕也是這樣類似添加
