C1WebTopicBar, a descendant from the C1WebCustomFlatControl class, is a flat type Web control since it only has two levels. The C1WebTopicBar provides users the possibility to implement elegant Windows XP – styled or custom designed navigation panels on their Web pages. C1WebTopicBar consists of groups that contain items. These items can be collapsed or expanded.

The C1WebTopicBar has a full range of capabilities, some of which are listed below:

·      Implementing cascading style sheets.

·      Combining built-in functions from other controls into the panel groups.

·      Dragging and dropping group headers.

·      Modifying or customizing the appearance of the C1WebTopicBar.

·      Enabling Ajax (Asynchronous JavaScript And XML) when expanding groups of data.

The C1WebTopicBar features a C1WebTopicBarGroup Collection Editor which provides ease-of-use editing to the C1WebTopicBar. As a result, it will take the user less time to create powerful navigation panels.
