Controls You Can Use on Web Forms ASP.NET Navigation Controls Menu Control
The Menu control exposes several properties to specify the visual rendering of the menu items in the control. The following table lists the available menu item styles you can specify for the Menu.
Instead of setting the individual style properties, you can specify styles that are applied to menu items based on their level by using the following style collections.
| Level style collections |
Description |
| LevelMenuItemStyles |
A collection of MenuItemStyle objects that control the style of the menu items on a level basis. |
| LevelSelectedStyles |
A collection of MenuItemStyle objects that control the style of selected menu items on a level basis. |
| LevelSubMenuStyles |
A collection of MenuItemStyle objects that control the style of the submenu items on a level basis. |
The first style in the collection corresponds to the style of the menu items at the first depth level in the menu tree. The second style in the collection corresponds to the style of the menu items at the second depth level in the menu tree, and so on. This is most often used to generate table of contents-style navigation menus where menu items at a certain depth should have the same appearance, regardless of whether they have submenus.
NOTE: If you use any of the level style collections listed in the previous table to define the style for the Menu control, these style settings override the individual menu item style properties.
Another way to alter the appearance of the control is to customize the images displayed in the Menu control. You can specify your own custom image for the different parts of the control by setting the properties shown in the following table.
| Image property |
Description |
| DynamicBottomSeparatorImageUrl |
An optional image displayed at the bottom of a dynamic menu item to separate it from other menu items. |
| DynamicPopOutImageUrl |
An optional image displayed in a dynamic menu item to indicate that it has a submenu. |
| DynamicTopSeparatorImageUrl |
An optional image displayed at the top of a dynamic menu item to separate it from other menu items. |
| ScrollDownImageUrl |
The image displayed at the bottom of a menu item to indicate that the user can scroll down to view additional menu items. |
| ScrollUpImageUrl |
The image displayed at the top of a menu item to indicate that the user can scroll up to view additional menu items. |
| StaticBottomSeparatorImageUrl |
An optional image displayed at the bottom of a static menu item to separate it from other menu items. |
| StaticPopOutImageUrl |
An optional image displayed in a static menu item to indicate that it has a submenu. |
| StaticTopSeparatorImageUrl |

The Menu control supports additional customization through templates, which offer more control over the rendering of certain elements. The following table lists the template types you can specify for the Menu.
| Template property |
Description |
| DynamicItemTemplate |
The template that contains the custom content to render for a dynamic menu item. |
| StaticItemTemplate |

You can control the vertical and horizontal position of a dynamic menu relative to its parent menu item by setting the DynamicVerticalOffset and DynamicHorizontalOffset properties, respectively. To control the indentation of the static submenu items within a static menu, use the StaticSubMenuIndent property.
