Changing the Expand / Collapse Animation

By default, the animation for the expand/collapse behavior of the C1TopicBar control is set to System, meaning that the behavior follows the settings of a user's operating system. If you'd rather have control over this, you can turn the animation on by setting to Animation property to On, or you can turn the animation off by setting the Animation to Off.

Using the Properties Window

Complete the following steps:

1. Navigate to the Toolbox and double-click the C1TopicBar icon. The C1TopicBar control is added to the form. Observe that one page, named Page 1, appears on the control by default. If you'd like to add more pages to the control, see Adding Topic Pages to the TopicBar.
2. Right-click the C1TopicBar control to open its context menu and then select Properties.
3. The Properties window opens with the C1TopicBar control's properties in focus.
4. Locate the Animation property, click its drop-down arrow, and select a setting from the list.

Using Code
