Limit numbers of item in gallery and show more as requested

Hi everyone!

I have a vertical gallery using collection with few hundred items. Now the user is asking to show only 10 items on visible (which I think can use FirstN() to achieve), but user also ask to have a button used to show 10 more items onto the current gallery every time selected.

Is there a way to achieve this requirement?

Thank everyone in advance for your support!!

Hi @ldanh

Add this to the OnVisible property of your screen.

Set(varShowNumber, 10)

Next, set the Items property of your gallery to this:

FirstN(YourCollection, varShowNumber)

Finally, on the button that increments the visible count by 10, add this to the OnSelect property:

Set(varShowNumber, varShowNumber + 10)

Hi @timl,

Excuse me for asking you again. Now I need to make the button only visible when the scroll reach the end of the gallery. Without reaching the end of the gallery the button will not be visible.
I'm not sure if there's a way to set a variable triggered at the end of the gallery.

Thank you so much for your help!!

Hi @ldanh - there is unfortunately no way to trigger the visibility of a control when a user reaches the end of a gallery.
