OnDefineMenu - cWebMenuBar

Parameter	Description
aMenu (ByRef)	tWebMenuItem array

Procedure OnDefineMenu tWebMenuItem[] ByRef aMenu

This event can be implemented to dynamically define a menu structure.

To define a menu structure, the tWebMenuItem array should be filled with items representing menu items. The entire menu should be defined at once and submenus can be placed in the aChildren array of tWebMenuItem. OnDefineMenu is called when the menu object is loaded on the client and when FullRefresh is called. If the dynamic menu items are clicked, the OnItemClick event fires in the object that defined the items.

Object oWebMenuButton is a cWebMenuButton
    Set psCaption to "Menu"
    Set pbMenuShowCaption to False
    
    Procedure OnDefineMenu tWebMenuItem[] ByRef aMenu

Defining Checkbox Menu Items

When using OnDefineMenu with a cWebMenuItemCheckbox, pbChecked is unavailable and thus the checked states need to be manually synced using UpdateItem.
