.net自带的Menu菜单实在不好看。
MagicLibrary此控件功能很强大，贴个下拉菜单的此控件用法。当然，此控件不仅仅只有这个用法，还有很多功能。比如说像VS.net这样的窗口控制、TabControl控件等等。
现举个例，用MagicLibrary做下拉菜单：

首先创建两个窗体Form1和Form2，再在主窗体Form1中加入ImageList控件。把所要的小图标加入到控件中。

（二）（TabControl控件）
MagicLibrary.dll控件功能中昨天写了个Menu的实现，全部以代码方式实现的一个例子。
在MagicLibrary.dll中，还一TabControl控件。
今天以拖拉方式（工具方法拖出）实现TabControl，其中加有Menu例子。
例子源码下载：/Files/HD/MagicLibrary_Demo/TabControlDemo.rar
截图如下：
例图一：
例图二：加入TabPage
例图三：关才已选择的TabPage
例图四：在已选择的TabControl中的RichTextBox控件右键菜单
例图五：TabControl控件的PositionTop属性设为flase
操作示例：
（界面设计）
项目中加入MagicLibrary.dll（包括解决方案资源管理器、工具箱中）。
项目中包括两个Form，分别为：Form1、Form2，Form1为起始Form。
打开Form1，在窗口设计器中从工具箱中拖入刚加入的控件：MenuControl，把MenuControl的Dock属性设为：Top，Name属性为：_topMenu，PositionTop属性设为：true，ShowArrows属性设为：true，ShowClose属性设为：true，ShrinkPagesToFit属性设为：false。接着再从工具箱中拖入：TabControl，把TabControl控件的Dock属性设为：Fill，Name属性为：_tabControl。
打开Form2，在窗口设计器中从工具箱中拖入控件：RichTextBox，把RichTextBox的Dock属性设为：Fill，Name属性设为：rtxContent
一：Form1
（代码实现）
打开Form1的代码设计器，在Form1的构造函数中加入：this.SetupMenu();
见源码：

见源码： public Form1() { // // Windows 窗体设计器支持所必需的 // InitializeComponent(); //加入菜单 this.SetupMenu(); }
接着复制这段代码到设计器中： /**//// <summary> /// 加入下拉菜单 /// </summary>
protected void SetupMenu() { Crownwood.Magic.Menus.MenuCommand top1 = new Crownwood.Magic.Menus.MenuCommand( "&PageControls" );
Crownwood.Magic.Menus.MenuCommand top1_1 = new Crownwood.Magic.Menus.MenuCommand( "&AddPage",new EventHandler( OnAddPageSelected ) );
Crownwood.Magic.Menus.MenuCommand top1_2 = new Crownwood.Magic.Menus.MenuCommand( "&RemovePage",new EventHandler( OnColseSelected ) );
Crownwood.Magic.Menus.MenuCommand top1_3 = new Crownwood.Magic.Menus.MenuCommand( "&Exit",new EventHandler( OnExitSelected ) );
top1.MenuCommands.AddRange( new Crownwood.Magic.Menus.MenuCommand[]{ top1_1,top1_2,top1_3 } );
Crownwood.Magic.Menus.MenuCommand top2 = new Crownwood.Magic.Menus.MenuCommand( "&TabControl" );
Crownwood.Magic.Menus.MenuCommand top2_1 = new Crownwood.Magic.Menus.MenuCommand( "&Top",new EventHandler( OnTopSelected ) );
Crownwood.Magic.Menus.MenuCommand top2_2 = new Crownwood.Magic.Menus.MenuCommand( "&Buttom",new EventHandler( OnButtomSelected ) );
top2.MenuCommands.AddRange( new Crownwood.Magic.Menus.MenuCommand[]{ top2_1,top2_2 } );
this._topMenu.MenuCommands.AddRange( new Crownwood.Magic.Menus.MenuCommand[]{ top1,top2 } );
this._tabControl.MouseUp += new MouseEventHandler( OnMouseUpTabPage ); } /**//// <summary> /// 加入页面 /// </summary>
protected void AddPage() { Form2 f2 = new Form2(); System.Windows.Forms.Control ctlForm = f2;
Crownwood.Magic.Controls.TabPage tp = new Crownwood.Magic.Controls.TabPage( "Page"+this._tabControl.TabPages.Count.ToString(),ctlForm );
this._tabControl.TabPages.Add( tp ).Selected = true; }
protected void OnExitSelected( object sender , EventArgs e )
{ DialogResult dr = MessageBox.Show( "Are you sure exit application?","Warning",MessageBoxButtons.YesNo,MessageBoxIcon.Warning );
if ( dr == DialogResult.Yes ) { Application.Exit(); } } protected void OnTopSelected( object sender,EventArgs e ) { this._tabControl.PositionTop = true; }
protected void OnButtomSelected( object sender , EventArgs e ) { this._tabControl.PositionTop = false; }
protected void OnAddPageSelected( object sender , EventArgs e ) { this.AddPage(); }
protected void OnMouseUpTabPage( object sender , System.Windows.Forms.MouseEventArgs e )
{ if ( this._tabControl.TabPages.Count>0 && e.Button == MouseButtons.Right && this._tabControl.SelectedTab.Selected )
{ Crownwood.Magic.Menus.MenuControl muMenu = new Crownwood.Magic.Menus.MenuControl();
Crownwood.Magic.Menus.MenuCommand menu1 = new Crownwood.Magic.Menus.MenuCommand( "&SavePage" );
Crownwood.Magic.Menus.MenuCommand menu2 = new Crownwood.Magic.Menus.MenuCommand( "&Close",new EventHandler( OnColseSelected ) );
Crownwood.Magic.Menus.PopupMenu pm = new Crownwood.Magic.Menus.PopupMenu();
pm.MenuCommands.AddRange( new Crownwood.Magic.Menus.MenuCommand[]{ menu1,menu2 } );
pm.TrackPopup( this._tabControl.PointToScreen( new Point( e.X,e.Y ) ) ); } }
protected void OnColseSelected( object sender , EventArgs e ) { if ( this._tabControl.TabPages.Count > 0 )
{ this._tabControl.TabPages.Remove( this._tabControl.SelectedTab ); } } （添加事件）打开Form1窗口设计器，选中TabControl控件，向控件加入MouseUp事件：
/**//// <summary> /// 单击TabControl关闭按钮时关闭已选择的TabPage /// </summary> /// <param name="sender"></param> ///
<param name="e"></param> private void _tabControl_ClosePressed(object sender, System.EventArgs e) { if ( this._tabControl.TabPages.Count > 0 )
{ this._tabControl.TabPages.Remove( this._tabControl.SelectedTab ); } } 二：Form2 打开Form2窗口设计器，选中RichTextBox，为RichTextBox控件添加MouseUp事件：
private void rtxContent_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e) { if ( e.Button == MouseButtons.Right )
{ System.Windows.Forms.RichTextBox rt = ( RichTextBox )sender; Crownwood.Magic.Menus.MenuControl muMenu = new Crownwood.Magic.Menus.MenuControl();
Crownwood.Magic.Menus.MenuCommand menu1 = new Crownwood.Magic.Menus.MenuCommand( "&Copy" );
Crownwood.Magic.Menus.MenuCommand menu2 = new Crownwood.Magic.Menus.MenuCommand( "&Cut" );
Crownwood.Magic.Menus.PopupMenu pm = new Crownwood.Magic.Menus.PopupMenu();
pm.MenuCommands.AddRange( new Crownwood.Magic.Menus.MenuCommand[]{ menu1,menu2 } ); pm.TrackPopup( rt.PointToScreen( new Point( e.X,e.Y ) ) ); } }
