You can add menu items to a menu control programmatically at application run-time by customizing the menu control’s code-behind file:
...\Menu Panels\menu.ascx.cs (.vb)
Override the Page_Load method in Section 1 and add this code:
MenuItem item = new MenuItem();
item.Text = "DynamicMenu1";
item.Value = "DynamicMenu1";
this.MultiLevelMenu.Items.Add(item);
You can display an image next to menu item text in a menu control by modifying or adding the imageUrl property in sitemap file. Each menu item for which an image is to be displayed should have the URL of the image specified in the sitemap file.
<siteMapNode title="{Menu:Add} Categories" description="{Menu:Add} Categories" url="~/Categories/AddCategories.aspx" imageUrl="~/Images/MenuAddRecord.gif" roles="" />
To display only the image and no menu item text, modify the menu control’s code-behind file, located in:
...\Menu Panels\menu.ascx.cs (.vb)
In Section 1, change the ModifyMenuItem() method to include this line:
e.Item.Text=”””;
