Menu.DisappearAfter Property

Note: This property is new in the .NET Framework version 2.0.

Gets or sets the duration for which a dynamic menu is displayed after the mouse pointer is no longer positioned over the menu.

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

[ThemeableAttribute(false)] 
public int DisappearAfter { get; set; }
/** @property */
public int get_DisappearAfter ()

/** @property */
public void set_DisappearAfter (int value)

public function get DisappearAfter () : int

public function set DisappearAfter (value : int)

Property Value

The amount of time (in milliseconds) a dynamic menu is displayed after the mouse pointer is no longer positioned over the menu. The default is 500.

By default, a dynamic menu automatically disappears after a certain duration when the mouse pointer is no longer positioned over the menu. Use the DisappearAfter property to specify the duration.

NoteNote

A dynamic menu disappears immediately if the user clicks outside of the menu.

You can also specify that a dynamic menu should never automatically disappear by setting this property to -1. In this case, the dynamic menu item will disappear only when the user clicks outside the menu.

This property cannot be set by themes or style sheet themes. For more information, see ThemeableAttribute and ASP.NET Themes and Skins Overview.

The following code example demonstrates how to use the DisappearAfter property to specify that a dynamic menu should disappear after the user moves the mouse pointer away from the menu for more than two seconds.
