WINFORM递归创建memustrip问题，请高手协助！！！！！！！！！！！

zl194 2009-11-30 10:42:31

写了半天也写不好，请哪位好心帮我写个例子，创建和调用，数据库表如下，不胜感激！！！

表是下面的样子



CREATE TABLE [tb_Auth] (

	[cAuth_Id] [varchar] (12) COLLATE Chinese_PRC_CI_AS NOT NULL ,

	[cAuth_Name] [varchar] (60) COLLATE Chinese_PRC_CI_AS NOT NULL ,	

	[cSupAuth_Id] [varchar] (12) COLLATE Chinese_PRC_CI_AS NULL ,

	CONSTRAINT [aaaaaUA_Auth_PK] PRIMARY KEY  NONCLUSTERED 

	(

		[cAuth_Id]

	)  ON [PRIMARY] 

) ON [PRIMARY]

GO



insert into tb_Auth

SELECT 'P01','基础设置','P' UNION ALL

SELECT 'P02','运行管理','P' UNION ALL

SELECT 'P03','查询分析','P' UNION ALL

SELECT 'P0101','档案','P01' UNION ALL

SELECT 'P0102','人员','P01' UNION ALL

SELECT 'P0201','启动','P02' UNION ALL

SELECT 'P0202','终止','P02' UNION ALL

SELECT 'P0203','调整','P02' UNION ALL

SELECT 'P020301','延时','P0203' UNION ALL

SELECT 'P020302','复制','P0203'

请哪位好心帮我写个例程吧，谢谢。

menuStrip1_ItemClicked仅针对一级菜单，就是横条上面的菜单
如果要每一个都响应，其他的子菜单你得设置DropDownItemClicked事件
就是说菜单的ItemClicked和DropDownItemClicked事件仅仅是指本身所包括的这一级，不再向下传递的
可以将4楼代码中的
menu.Click += new EventHandler( menu_Click );
换成
menu.DropDownItemClicked += new ToolStripItemClickedEventHandler( menuStrip1_ItemClicked );

谢谢楼上两位了，非常感谢！
另外我想让所有的菜单都执行相同的处理事件程序，但是不知怎么的，只有第一级菜单能执行，如果两位回来帮我再看一下。我用的事件是下面的。



        private void menuStrip1_ItemClicked(object sender, ToolStripItemClickedEventArgs e)

        {

            MessageBox.Show(e.ClickedItem.Name.ToString());

        }

点击第一级菜单没问题，第二级就没反应。

这里用的是DataTable,楼主可以根据需要换成其他的



        private void button1_Click( object sender, EventArgs e )

        {

            DataTable dt = GetTable();



            //从顶级菜单开始加载

            LoadSubMenu( dt, "P", menuStrip1.Items );



        }



        /// <summary>

        /// 递归加载子菜单

        /// </summary>

        /// <param name="dt">菜单数据表</param>

        /// <param name="supauthid">父菜单ID</param>

        /// <param name="parent">父菜单集合</param>

        private void LoadSubMenu( DataTable dt, string supauthid, ToolStripItemCollection parent )

        {

            DataRow[] rows = dt.Select( string.Format( "cSupAuth_Id='{0}'", supauthid ) );

            foreach ( var item in rows )

            {

                ToolStripMenuItem menu = new ToolStripMenuItem( item["cAuth_Name"].ToString() );

                

                parent.Add( menu );



                LoadSubMenu( dt, item["cAuth_Id"].ToString(), menu.DropDownItems );



                if ( menu.DropDownItems.Count == 0 )

                {

                    //如果没有子菜单，则绑定事件

                    menu.Click += new EventHandler( menu_Click );

                }

            }

        }



        /// <summary>

这个是递归生成工具栏按钮，原理一样的
