contextMenuStrip添加菜单项

一.简单添加

(1)this.contextMenustrip1.Item.Add(“toolstripMenuitem1”)------------------添加单个菜单项

(2)this.contextMenustrip1.Item.AddRange(new System.windows.forms.ToolstripItem[]{this.toolstripMenuItem1,this.toolstripMenuItem2.....})----------添加多个菜单项

二.动态添加，同时添加对应点击事件

(1)首先实例化几个ToolStripItem（要为父级添加几个就实例化几个）

      //添加子菜单      toolStripItem    ts_1=new   toolStripItem("里面的text文本")；  //实例化一个

                                 ToolStripItem[] Tsi = new ToolStripItem[count];     //数组

(2)将其添加到ContextMenuStrip

((ToolStripDropItem)(contextMenustrip1.item[1])).DropdownIem.Add(ts_1);

(3)在实例化ToolStripItem要为实例化的ToolStripItem对象添加新的事件，然后再添加到ContextMenuStrip控件

ts_1.click+=new EventHandler(ts_1_click);

(4)添加ts_1_click方法

private void ts_1_click(object sender,EventArgs e)

{}

eg:动态添加

  private void btPrint_Click(object sender, EventArgs e)
        {
            this.contextMenuStrip2.Items.Clear();
            DataTable dt = DAL.TorchLabQuery.Query_ReportFormat(tbscpmc.Text);//通过报告导出格式表中的产品名称得到报告格式
            int count = dt.Rows.Count;
            ToolStripItem[] Tsi = new ToolStripItem[count];
            for(int i=0;i<count;i++)
           {
               this.contextMenuStrip2.Items.Add(dt.Rows[i]["ReportFormat"].ToString());
               this.contextMenuStrip2.Items[i].Click += new EventHandler(ts_1_click);    //对应的点击事件
           }
            contextMenuStrip2.Show(btPrint, 0, btPrint.Height);
        }

 private void ts_1_click(object sender,EventArgs e)
        {
            ToolStripMenuItem Tsm = (sender as ToolStripMenuItem);   
            string name = Tsm.Text;
            。。。。。。
        }
