在Load里面新增如下代码使用：AnchorPanel APanel; private void Form3_Load(object sender, EventArgs e) { APanel = new AnchorPanel(panel1, xtraScrollableControl1); labelControl1.Text = groupControl6.Height.ToString(); if (groupControl6.Height < xtraScrollableControl1.Height) groupControl6.Height = xtraScrollableControl1.Height; panel1.Controls.Clear(); APanel.AddAnchor(groupControl1, false); APanel.AddAnchor(groupControl2, false); APanel.AddAnchor(groupControl3, false); APanel.AddAnchor(groupControl4, false); APanel.AddAnchor(groupControl5, false); APanel.AddAnchor(groupControl6, true); APanel.CurrentLable = APanel.GetMenu(0); } Demo下载地址：https://github.com/GarsonZhang/JumpPanel
