Occurs on the client side when a submenu pops up.
PopUp: ASPxClientEvent<ASPxClientMenuItemEventHandler<ASPxClientMenuBase>>
The PopUp event's data class is ASPxClientMenuItemEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| item | Gets the menu item object related to the event. |
The PopUp event occurs on the client side when a menu item’s submenu pops up within a particular menu object (the ASPxMenu or ASPxPopupMenu). For a menu object of the ASPxPopupMenu type, this event is also fired when the popup control appears.
The PopUp event provides an argument of the ASPxClientMenuItemEventArgs type. The event argument’s ASPxClientMenuItemEventArgs.item property allows you to access the menu item whose submenu is invoked.
If the PopUp event is raised for a popup menu control, the event argument’s ASPxClientMenuItemEventArgs.item property returns null.
