解决方案2：不隐藏ShowExpandButton实现NavBarControl自动缩放。

打开frmMain.cs文件，添加以下代码：

C# Code:

//NavBarControl尺寸改变时的标记
private bool _OnSizeChangingNavBar = false;

private void navBarControl1_SizeChanged(object sender, EventArgs e)
{
  if (_OnSizeChangingNavBar) return;
  if (_OnSizeChangingDock) return;
  
  try
  {
    _OnSizeChangingNavBar = true;
    
    if (dockPanel1.Visibility == DockVisibility.Visible && navBarControl1.Visible && navBarControl1.Width > 0)
    {
      dockPanel1.Width = navBarControl1.Width;
    }
  }
  finally
  {
    _OnSizeChangingNavBar = false;
  }
}

修改原有dockPanel1_SizeChanged事件的代码：

C# Code:

//Doc组件尺寸改变时的标记
private bool _OnSizeChangingDock = false;

//frmMain.dockPanel1_SizeChanged
private void dockPanel1_SizeChanged(object sender, EventArgs e)
{
  if (_OnSizeChangingDock) return;
  
  try
  {
    this.SuspendLayout();
    _OnSizeChangingDock = true;
    
    navBarControl1.Dock = DockStyle.None;
    navBarControl1.Left = xtraScrollableControl1.DisplayRectangle.X;//滚动容器的实际坐标
     navBarControl1.Top = xtraScrollableControl1.DisplayRectangle.Y;//滚动容器的实际坐标
     navBarControl1.NavigationPaneGroupClientHeight = 100;//导航按钮展开显示明细菜单区域的高度。
     navBarControl1.Height = navBarControl1.Groups.Count * 70 + navBarControl1.NavigationPaneGroupClientHeight;//手工指定NavBar组件的高度
     navBarControl1.OptionsNavPane.ShowOverflowButton = false;//不显示底部的动态扩展按钮
     navBarControl1.OptionsNavPane.ShowOverflowPanel = false;//不显示底部的动态扩展按钮区域
     xtraScrollableControl1.HorizontalScroll.Visible = false;//不显示横向滚动条
    
    //若NavBar显示垂直滚动条，要预留明细区域的滚动条，约25个像素
     if (xtraScrollableControl1.VerticalScroll.Visible)
    navBarControl1.Width = dockPanel1.Width - 25;//右侧预留边距
     else
    navBarControl1.Width = dockPanel1.Width - 5;//右侧预留边距
    
    //NavBar全屏自适应高度
     if (dockPanel1.ClientSize.Height - 60 > navBarControl1.Height)
    navBarControl1.Height = dockPanel1.ClientSize.Height - 60;
    
  }
  finally
  {
    _OnSizeChangingDock = false;
    this.ResumeLayout();
  }
}
