【转】ContextMenuStrip菜单应用

测试可用的代码：

#region   右键快捷菜单单击事件
        private void contextMenuStrip1_ItemClick(object sender, EventArgs e)
        {
            ToolStripItem item = (ToolStripItem)sender;
            Clipboard.SetText(item.Text); //把要插入的文本放到剪切板
            SendKeys.Send("^v"); // 模拟ctrl+v
        }
 #endregion

         //写右键快捷菜单控件
                for (int i = 0; i < DataClass.ClassCustomParameter.intRowCountCustomParmeter; i++)
                {
                    ToolStripMenuItem menuitem;
                    menuitem = new ToolStripMenuItem();
                    menuitem.Text = DataClass.ClassCustomParameter.strCustomParameter[i, 0];
                    menuitem.Name = "tllStripMenu" + i;
                    menuitem.Click += new EventHandler(contextMenuStrip1_ItemClick);
                    contextMenuStrip1.Items.Add(menuitem);
                }
                //各控件绑定右键快捷菜单
                textBoxCaseReason.ContextMenuStrip = contextMenuStrip1;

　　

【转】ContextMenuStrip菜单应用

ContextMenuStrip 控件提供了与某个控件关联的快捷菜单。也就是说通过这个控件可以方便的实现在别的控件上弹出右键快捷菜单。

例子：

1、先添加一个ContextMenuStrip 控件到Form上 
2、设置目标控件（如窗体、文本框等）的ContextMenuStrip属性，指向你刚才添加的ContextMenuStrip 控件。这样就实现了两者的关联。 
3、动态将一些菜单项添加到 ContextMenuStrip 控件中，如： 
//上下文菜单项 
ContextMenuStrip1.Items.Add(msEditNew); 
ContextMenuStrip1.Items.Add(msEditBar1); 
ContextMenuStrip1.Items.Add(msEditCut); 
ContextMenuStrip1.Items.Add(msEditPaste); 
ContextMenuStrip1.Items.Add(msEditDelete); 
ContextMenuStrip1.Items.Add(msEditBar2);

这样就OK了，你在目标控件上按右键时将弹出快捷菜单。

 

 

 

动态添加ContextMenuStrip项（ToolStripItem）

        //绑定菜单
        private void BindMenu(DataTable dt)
        {
            foreach (DataRow row in dt.Rows)
            {
                ToolStripItem item = new ToolStripMenuItem();
                item.Name = row[0].ToString();
                item.Text = row[1].ToString();
                item.Click += new EventHandler(contextMenuStrip1_ItemClick);
                contextMenuStrip1.Items.Add(item);
                //contextMenuStrip1.Items.Add(row[1].ToString(), null, contextMenuStrip1_ItemClick);
            }
        }

        private void contextMenuStrip1_ItemClick(object sender, EventArgs e)
        {
            ToolStripItem item = (ToolStripItem)sender;            
            MessageBox.Show(item.Name);
        }
