C#仿QQ设置界面导航

效果预览，选择左边标签，右边内容会自动滚动到适当位置

PS：界面新建一个panel1，用于存放左边的导航列表，右边拖一个dev控件：xtraScrollableControl1
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);
            
            
            
            
            
       }
