## 实现 ##

前面已经将鼠标的右键事件与方法绑定

this.zedGraphControl1.ContextMenuBuilder += MyContextMenuBuilder;

### 在方法MyContextMenuBuilder中 ###

//新建菜单项对象
                ToolStripMenuItem item1 = new ToolStripMenuItem();
                //设置名字
                item1.Name = "line_set";
                //设置显示文本
                item1.Text = "霸道流氓";
                //点击事件与方法绑定
                item1.Click += mouseEnter;
                //菜单项添加到右键菜单
                menuStrip.Items.Add(item1);

实现了添加一个右键菜单，将其点击事件与mouseEnter方法绑定。

### 在窗体类下定义事件 ###

//MouseEventHandler :表示将处理窗体、控件或其他组件的 MouseDown、MouseUp 或 MouseMove 事件的方法。
            // event关键字代表事件，返回类型为委托；
            public static event EventHandler mouseEnter;

然后在初始化窗体的位置将事件与自定义方法相绑定。

public Form1()
            {
                InitializeComponent();
                //Form1初始化后创建设置控件的方法并将当前ZedGraph控件传递
                createPane(zedGraphControl1);
                //事件与方法绑定
                mouseEnter += new EventHandler(OnmouseEnter);
    
            }

### 完整MyContextMenuBuilder方法 ###

private static void MyContextMenuBuilder(ZedGraphControl control, ContextMenuStrip menuStrip,
                        Point mousePt, ZedGraphControl.ContextMenuObjectState objState)
            {
                //新建菜单项对象
                ToolStripMenuItem item1 = new ToolStripMenuItem();
                //设置名字
                item1.Name = "line_set";
                //设置显示文本
                item1.Text = "霸道流氓";
                //点击事件与方法绑定
                item1.Click += mouseEnter;
                //菜单项添加到右键菜单
                menuStrip.Items.Add(item1);
                //汉化右键菜单
                foreach (ToolStripMenuItem item in menuStrip.Items)
                {
                    switch (item.Name)
                    {
                        case "copied_to_clip":
                            item.Text = @"复制到剪贴板";
                            break;
                        case "copy":
                            item.Text = @"复制";
                            break;
                        case "page_setup":
                            item.Text = @"页面设置...";
                            break;
                        case "print":
                            item.Text = @"打印...";
                            break;
                        case "save_as":
                            item.Text = @"另存图表...";
                            break;
                        case "set_default":
                            item.Text = @"恢复默认大小";
                            break;
                        case "show_val":
                            item.Text = @"显示节点数值";
                            break;
                        case "title_def":
                            item.Text = @"标题";
                            break;
                        case "undo_all":
                            item.Text = @"还原缩放/移动";
                            break;
    
                        case "unpan":
                            item.Text = @"还原移动";
                            break;
    
                        case "unzoom":
                            item.Text = @"还原缩放";
                            break;
    
                        case "x_title_def":
                            item.Text = @"X 轴";
                            break;
                        case "y_title_def":
                            item.Text = @"Y 轴";
                            break;
    
                    }
                }
            }
