Property Value

Type	Default	Description
Int32	300

An integer value that specifies the time interval, in milliseconds, after which submenus get displayed within a menu control.

Remarks

When an end-user positions the mouse pointer over a menu item that contains a submenu, the submenu’s appearance can be delayed by a specific duration. Use the AppearAfter property to specify the duration, that represents the delay in displaying submenus within a menu control. Invoking a submenu utilizes a predefined animation effect, if the ASPxMenuBase.EnableAnimation property is enabled.

For the ASPxPopupMenu control, this AppearAfter property also affects the delay in invoking the root popup menu (the popup menu control itself), when a specific client action specified by the ASPxPopupMenu.PopupAction property is performed.

Example

This part of the Tabbed Menu demo illustrates how to customize the ASPxMenu control as a hierachical menu (with popped out submenus) which looks like a set of tabs.

Gradient borders for the menu’s root items (tabs) are drawn by using the RootItemTextTemplate property. The control’s style settings are defined via the ASPxMenuBase.ItemStyle property, ASPxMenuBase.SubMenuStyle property,etc.
