DevExpress, der bekannte Anbieter von Controls für Winforms, WPF und Silverlight bietet sein AgMenu für Silverlight kostenlos an.

Key Features

• Popup Menu Control – a standalone control allowing you to enhance your application’s usability with context commands.
• Flexible Appearance Customization – if you need to change the look and feel of menu items, you don’t necessarily have to assign the same template to each and every item in the hierarchy. AgMenu allows you to specify menu-level and submenu-level settings so you can enable common templates for items, sub-menu items and separators.
• Reading Menu Structure from XML Files – menu hierarchy can be described in an external XML file that can be bound to the menu control. Data binding is specified in XAML, so no coding is required.
• Animation Effects – when showing submenus, DevExpress Silverlight Menu controls can use three different animation effects – fading, sliding and scrolling.
• Submenu Scrolling – if a child list doesn’t fit into the browser window, scroll buttons allow end-users to access all commands in that list.
• Checked Items – menu items can support checked and unchecked states thus indicating to end-users if an option has been enabled.
• Radio Group Items – DevExpress Silverlight Menu controls allow you to join items into radio groups, thus allowing only one item in a group to be checked at a time.
• Full Support for Templates – menu content customization has no limits since you can use Templates to embed any content into items and submenus.
• Toolbar Emulation – with the DevExpress Silverlight menu, it’s extremely easy to create Microsoft Office style toolbars.
