Carousel.ItemRealizing

[zigzigzig]

Hello All,

Toying around with carousel controls, trying to implement external buttons that appear and reappear based on carousel item entry:

Code: Select all

Evtroutine Handling(#Button1.Click)
#Carousel1.previtem Animate(False)
Endroutine

Evtroutine Handling(#Button2.Click)
#Carousel1.nextitem Animate(False)
Endroutine

Evtroutine Handling(#Carousel1.ItemRealizing) Item(#theItem)
#sys_web.console.log Text(#Carousel1.currentItem.entry.asString)
#Button1.visible := (*Not (#Carousel1.currentItem.Entry = 1))
#Button2.visible := (*Not (#Carousel1.currentItem.entry = #Carousel1.items.itemcount))
Endroutine
End_Com

It seems the itemRealized event is only firing once, sometimes twice? And yeah, I have the designCreation property set to OnViewing.
This seems really simple, but the event seems to be firing once or twice and then never again.
Any ideas?

It looks as though there's an issue with Carousel. Please report this to your regional help desk

The simple work around is to manage the "CurrentItem" yourself.

Assuming a design instance per page, something like the following should work

Code: Select all

Mthroutine Name(ShowItem)
Define_Map For(*Input) Class(#Prim_nmbr) Name(#Item)

#CurrentItem := #Item

#Carousel.MoveToItem( #CurrentItem )

#Previous.Enabled := #CurrentItem > 1
#Next.Enabled := #CurrentItem <> #Carousel.Items.ItemCount

Endroutine

Evtroutine Handling(#Next.Click)

#com_owner.ShowItem( (#CurrentItem + 1) )

Endroutine

Evtroutine Handling(#Previous.Click)

#com_owner.ShowItem( (#CurrentItem - 1) )

Endroutine
