Typically, you will use the following properties to customize the appearance of NavBar elements at the View level:

• NavBarViewBase.ItemImageSettings and NavBarViewBase.GroupImageSettings - Specify the display regions and stretch modes for element images.
• NavBarViewBase.ItemFontSettings and NavBarViewBase.GroupFontSettings - Specify font settings applied to the element text.
• NavBarViewBase.ItemLayoutSettings and NavBarViewBase.GroupLayoutSettings - Specify the position and alignment of element text and images.
• NavBarViewBase.ItemDisplayMode and NavBarViewBase.GroupDisplayMode - Specify whether image only, text only or both image and text are displayed for NavBar elements.

At the group and item levels, you can use the settings listed below to customize the appearance of NavBar elements:

• NavBarGroup.ImageSettings, NavBarGroup.ItemImageSettings and NavBarItem.ImageSettings.
• NavBarGroup.FontSettings, NavBarGroup.ItemFontSettings and NavBarItem.FontSettings.
• NavBarGroup.LayoutSettings, NavBarGroup.ItemLayoutSettings and NavBarItem.LayoutSettings.
• NavBarGroup.DisplayMode, NavBarGroup.ItemDisplayMode and NavBarItem.DisplayMode.

Settings specified at the group level override settings defined at the View level. Similarly, item-level settings override settings defined at the View and group levels.

When an advanced appearance customization is required, you can use the NavBarViewBase.GroupVisualStyle, NavBarViewBase.ItemVisualStyle, NavBarGroup.ItemVisualStyle, NavBarGroup.VisualStyle and/or NavBarItem.VisualStyle properties. Styles assigned to these properties target visual objects that visualize NavBar items and groups.

To learn more about style customization, see the Styling View Content Elements topic.

Example

This example demonstrates how the appearance of groups and items can be customized at different levels within the NavBarControl by using specific style properties. To learn more about appearance customization, please refer to Styling View Content Elements.
