我使用此代码创建一个动态菜单:

private void PopulateMenu()

    {

        DataSet ds = GetDataSetForMenu();

 

        Menu menu = new Menu();

        //menu.MenuItemClick += new MenuEventHandler(menu_MenuItemClick);

        foreach (DataRow masterRow in ds.Tables[0].Rows)

        {

            MenuItem masterItem = new MenuItem(" " + (string)masterRow["pkg_name"] + " ");

            menu.Items.Add(masterItem);

            foreach (DataRow childRow in masterRow.GetChildRows("Children"))

            {

 

                MenuItem childItem = new MenuItem((string)childRow["city"] + "<hr />");

                masterItem.ChildItems.Add(childItem);

 

                childItem.NavigateUrl = ((string)childRow["url"]) + "?id=" + ((int)childRow["city_id"]);

            }

 

        }

        //foreach (DataRow parentItem in ds.Tables["City"].Rows)

        //{

        //    MenuItem categoryItem = new MenuItem((string)parentItem["city"]);



        //    menu.Items.Add(categoryItem);



        //    foreach (DataRow childItem in parentItem.GetChildRows("Children"))

        //    {

        //        MenuItem childrenItem = new MenuItem((string)childItem["Hotel_name"]);

        //        categoryItem.ChildItems.Add(childrenItem);

        //    }

        //}



        Panel1.Controls.Add(menu);

        Panel1.DataBind();

    }

 

    private DataSet GetDataSetForMenu()

    {

        SqlConnection myConnection = new SqlConnection(GetConnectionString());

        SqlDataAdapter adCat = new SqlDataAdapter("SELECT * FROM Package", myConnection);

        SqlDataAdapter adProd = new SqlDataAdapter("SELECT * FROM City", myConnection);

 

        DataSet ds = new DataSet();

        adCat.Fill(ds, "Package");

        adProd.Fill(ds, "City");

 

        ds.Relations.Add("Children", ds.Tables["Package"].Columns["pkg_id"], ds.Tables["City"].Columns["pkg_id"], false);

        return ds;

    }

 

    private string GetConnectionString()

    {

        string connectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;

        return connectionString;

    }

菜单面板中创建。我有一个锚标记酒店预订。我希望面板是可见的onmouseover酒店预订。我怎么能这样做吗？

请指导我。

预先感谢
