MenuItemStyleCollection.Add Method

Appends the specified MenuItemStyle object to the end of the current collection.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public int Add(
	MenuItemStyle style
)

Parameters

style
Type: System.Web.UI.WebControls.MenuItemStyle
The MenuItemStyle to append to the end of the current collection.

Return Value

Type: System.Int32
The zero-based index of the added MenuItemStyle.

Use the Add method to append the specified MenuItemStyle object to the end of the collection. As an alternative, you can insert a MenuItemStyle object into the collection at a specific index by using the Insert method.

The following code example demonstrates how to use the MenuItemStyleCollection class to specify the style settings for the menu items in a Menu control based on the menu item's level. In this example, the LevelMenuItemStyles property is created declaratively, and one MenuItemStyle object is removed and another added to the MenuItemStyleCollection object.
