Navigation Menu Default Issue

(0) Share

Report

Posted on by omd001

I have created a navigation menu using Collections.

I can navigate from various screens well when clicking on the individual menu. However, if I come from another screen with a Home button on it, I am being redirected to the Home screen perfectly, but the menu being highlighted is the second item in my gallery.

I tried putting the following on the Home Screen's gallery's Default setting but to no avail.

Lookup(NavigationMenu, Row=1)

In the FillTemplate, I have the following:

If(ThisItem.Row = _selectedTutorial.Row, RGBA(220, 220, 220, 1), RGBA(0,0,0,0))

Hi @omd001 ,

What exactly is NavigationMenu (is it a List) and is Row a field in the list?

Hi @WarrenBelz, thanks for your speedy reply.
It is a collection, see below. The idea is actually from this blog, however it didn't specify defaulting a gallery item for an individual screen.

Hi @omd001 ,

The Default should be OK (except for the capitalising of LookUp)

LookUp( NavigationMenu, Row=1 )

The TemplateFill can simply be

If( ThisItem.IsSelected, RGBA(220, 220, 220, 1), White )

Please click Accept as solution if my post helped you solve your issue. This will help others find it more readily. It also closes the item. If the content was useful in other ways, please consider giving it Thumbs Up.

Hi @WarrenBelz , I have tried that many times but to no avail. I tried the following:

1. In Home Screen > Gallery > Default:
LookUp( NavigationMenu, Row=1 )
2. In Screen 2 > Gallery > Default
LookUp( NavigationMenu, Row=2 )
etc.

I found the answer @WarrenBelz
I have to set the Screen's OnVisible to the following:

Set(yourvariable, {Row: 1, Title: "Home", Image: yourimage})

And then you have to do the same for other screens with the correct Row ID.
