在右键菜单ContextMenuStrip下添加子菜单选项可以通过
ContextMenuStrip menuStrip ToolStripMenuItem mnuChartOption = new ToolStripMenuItem(); //新建菜单项对象 mnuChartOption.Name = "chart_option"; mnuChartOption.Text = "图形选项"; //点击弹出图形选项对话框 mnuChartOption.Click += delegate(object sender, EventArgs e) { }; menuStrip.Items.Add(mnuChartOption);
来实现。但是如果在右键菜单的子菜单选项下再添加子菜单选项,形成二级子菜单。

ToolStripMenuItem 的子级菜单仍然是ToolStripMenuItem ,主要通过DropDownItems属性来构建关联关系。
构建右键二级子菜单示例代码
ToolStripMenuItem mnuDirectPrint = new ToolStripMenuItem("直接打印"); mnuDirectPrint.Name = "directPrint"; mnuDirectPrint.Text = "直接打印"; mnuDirectPrint.Click += delegate(object sender, EventArgs e) { control.DoPrint(); }; ToolStripMenuItem mnuPrintPageSet = new ToolStripMenuItem("打印页面设置"); mnuPrintPageSet.Name = "printPageSet"; mnuPrintPageSet.Text = "打印页面设置"; mnuPrintPageSet.Click += delegate(object sender, EventArgs e) { control.DoPageSetup(); }; ToolStripMenuItem mnuPrint = new ToolStripMenuItem(); mnuPrint.Name = "mnuPrint"; mnuPrint.Text = "打印"; mnuPrint.DropDownItems.Add(mnuDirectPrint); mnuPrint.DropDownItems.Add(mnuPrintPageSet); menuStrip.Items.Add(mnuPrint);
