示例效果：
FrameForm分为上左右三区
上区显示TopUC的顶部Logo及欢迎语
左区显示LeftMenuUC的左侧功能按钮菜单
右区显示点击左侧功能按钮后对应的用户控件窗体内容
(事实上功能按钮应该由传统的WinForm菜单来代替 WinForm程序就应该有自己的传统的样式 而不是和Web类似
不过为了类似于web系统的框架页面
所以尝试了本示例)
示例涉及的窗体及用户控件：
FrameForm 框架窗体 包含两个SplitContainer
SplitContainer1对窗体上下分隔
SplitContainer2对SplitContainer1的Panel2进行左右分隔
TopUC 顶部用户控件
LeftMenuUC 左侧菜单用户控件 其中包含两个功能按钮button1 button2
ContentUC1 内容用户控件1 为button1所调用 将显示的框架的右区
ContentUC2 内容用户控件2 为button1所调用 将显示的框架的右区
