Prasad，



尝试以下方法，可能效率最高但效果不错。



这是ASPX

Prasad,

Try the following, might not be most efficient but works.

Here is the ASPX

<dx:ASPxRoundPanel ID="ASPxRoundPanel2" HeaderText="Some Menu" runat="server" Width="205px"

    Theme="Office2010Blue">
    <PanelCollection>
        <dx:PanelContent>

            <dx:ASPxNavBar ID="ASPxNavBar1" runat="server" Theme="Office2010Blue" Width="100%">
            </dx:ASPxNavBar>

        </dx:PanelContent>
    </PanelCollection>
</dx:ASPxRoundPanel>

这是c＃代码......

Here is the c# Code...

public partial class uc_menu : System.Web.UI.UserControl
    {
        List<MenuInfo> menuItems = new List<MenuInfo>();
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                int i = 1;
                // I am populating my list with Menu Items. You could easily substitute a data from a Database
                menuItems.Add(new MenuInfo() { MenuId = i++, MenuName = "ItemName1", MenuText = "itemText1", MenuUrl = @"http://Somesite/Page1.aspx", MenuGroup = "Group1" });
                menuItems.Add(new MenuInfo() { MenuId = i++, MenuName = "ItemName2", MenuText = "itemText2", MenuUrl = @"http://Somesite/Page2.aspx", MenuGroup = "Group1" });
                menuItems.Add(new MenuInfo() { MenuId = i++, MenuName = "ItemName3", MenuText = "itemText3", MenuUrl = @"http://Somesite/Page3.aspx", MenuGroup = "Group3" });
                menuItems.Add(new MenuInfo() { MenuId = i++, MenuName = "ItemName4", MenuText = "itemText4", MenuUrl = @"http://Somesite/Page4.aspx", MenuGroup = "Group1" });
                menuItems.Add(new MenuInfo() { MenuId = i++, MenuName = "ItemName5", MenuText = "itemText5", MenuUrl = @"http://Somesite/Page5.aspx", MenuGroup = "Group2" });
            }

            // My Method to build the Menu Items. 
            // I pass in my NavBar Control, List of menuItems I created above and a Title for the Round Panel Control
            //
            BuildNavBarItems(this.ASPxNavBar1, menuItems, "Main Menu Title");

        }

        private void BuildNavBarItems(ASPxNavBar navbar, List<MenuInfo> menuitems, string menutitle)
        {

            // Set the Title
            this.ASPxRoundPanel2.HeaderText = menutitle;
            string navUrl = string.Empty;
            
            // I use a Dictionary object to keep track of the Menu Groups

            Dictionary<string, NavBarGroup> navGroups =
                new Dictionary<string, NavBarGroup>();

            // Clear the Items to start fresh.
            navbar.Groups.Clear();


            foreach (MenuInfo m in menuitems)
            {
                navUrl = m.MenuUrl;

                // If the Key Exists in the Dictionary add the new Item to the items collection of that NavGroup
                if (navGroups.ContainsKey(m.MenuGroup))
                    navGroups[m.MenuGroup].Items.Add(new NavBarItem(m.MenuText, "", "", navUrl));
                else
                {
                    // Otherwise we add a new navGroup to the Navbar collection, add the navbarItem to it and store it in the dictionary
                    NavBarGroup navgroup = navbar.Groups.Add(m.MenuGroup, m.MenuGroup);
                    navgroup.Items.Add(new NavBarItem(m.MenuText, "", "", navUrl));
                    navGroups.Add(m.MenuGroup, navgroup);
                }
            }
        }

        private class MenuInfo
        {
            public int MenuId { get; set; }
            public string MenuName { get; set; }
            public string MenuText { get; set; }
            public string MenuUrl { get; set; }
            public string MenuGroup { get; set; }
        }
    }

我希望这会有所帮助。
