Remarks
Use the MenuItemStyle class to represent the style of a menu item in the Menu control. A menu item is displayed in either a static menu or a dynamic menu. A static menu is always displayed in a Menu control, whereas a dynamic menu is displayed only when the user positions the mouse pointer over a parent menu item that contains a dynamic submenu. You can specify different style characteristics (such as font size and color) for each of the different menu item types. The following table lists the available menu item styles.
| Menu item style property | Description |
|---|---|
| DynamicHoverStyle | The style settings for a dynamic menu item when the mouse pointer is positioned over it. |
| DynamicMenuItemStyle | The style settings for an individual dynamic menu item. |
| DynamicMenuStyle | The style settings for a dynamic menu. |
| DynamicSelectedStyle | The style settings for the currently selected dynamic menu item. |
| StaticHoverStyle | The style settings for a static menu item when the mouse pointer is positioned over it. |
| StaticMenuItemStyle | The style settings for an individual static menu item. |
| StaticMenuStyle | The style settings for a static menu. |
| StaticSelectedStyle | The style settings for the currently selected static menu item. |
When multiple style properties are set for a static menu item, the style properties are applied in the following order:
StaticMenuItemStyle. If the LevelMenuItemStyles collection or LevelSubMenuStyles collection is defined, it is applied at this time, overriding the other menu item style properties.
StaticSelectedStyle. If the LevelSelectedStyles collection is defined, it is applied at this time, overriding the other menu item style properties.
Likewise, the style properties for a dynamic menu item are applied in the following order:
DynamicMenuItemStyle. If the LevelMenuItemStyles collection or LevelSubMenuStyles collection is defined, it is applied at this time, overriding the other menu item style properties.
DynamicSelectedStyle. If the LevelSelectedStyles collection is defined, it is applied at this time, overriding the other menu item style properties.
The MenuItemStyle class inherits most of its members from the Style class. It extends the Style class by providing properties that control the amount of space around a menu item's text, as well as the space between adjacent menu items. Use the HorizontalPadding property to control the amount of space to the left and right of the menu item's text. Similarly, the VerticalPadding property controls the amount of space above and below the menu item's text. You can control the amount of spacing between the menu item that the MenuItemStyle object is applied to and its adjacent menu items by setting the ItemSpacing property.
For more information on the inherited style settings, see Style.
