ASP.NET NavBar, SiteMap and Tag Cloud
for Web Forms and MVC

The UI Elements that make up the NavBar include Groups, Group Headers, Group Content, Group Expand Buttons, Group Header Image, Items, Item Image and Loading Panel. Countless customization options provide precise control over its design and layout.

Our ASP.NET NavBar control supports standard data binding. Any object which implements the IHierarchicalEnumerable or IHierarchicalDataSource interface (e.g. SiteMapDataSource, XmlDataSource) may be used as a data source for this control.

The ItemLinkMode property specifies how navbar items are represented as links within the navbar control. By default, this property is set to ContentBounds which makes the navbar entirely interactive. If you need to display a simple navbar (such as a set of links within groups), set the ItemLinkMode property to TextOnly.

Available options include:

• Text Only
• Text and Image
• Content Bounds

Predefined bullet styles:

• Circle
• Decimal
• Disc
• Lower Alpha / Upper Alpha
• Lower Roman / Upper Roman
• Square

Our ASP.NET NavBar control supports AJAX technology by implementing the ability to load the content of a group from the server via a callback when the group is expanded. This approach allows the navbar to avoid the initial transfer of all its group's data to the client.

Turn on the EnableCallBacks option to enable the use of callbacks. In this instance, the contents of the collapsed groups are not represented on the client. When a group is expanded for the first time, its content is retrieved from the server and then cached on the client. The next time the group is expanded, its content is taken from the client and no callback to the server is performed.

The look of each basic element of the navbar control can be completely changed by creating a specific template which defines how the element will be rendered by a client browser.

Tag Cloud items are rendered as hyperlinks. A click on this link navigates the application to the specified location. The larger the item's weight, the more popular the item. Popular items have larger font sizes.

The ShowValues property allows an element's rank (weight) to be displayed together with the element's caption.
