Auto scroll gallery

Hi, I'm trying to build a auto scroll gallery using a timer. I see that the entire gallery is moving outside the screen just showing a scrolling effect when the timer starts. Is it possible to scroll the gallery items dynamically without moving the entire gallery? Any solution to this would help a lot.

This is the code I have used:

OnTimerEnd - Set(myScrollValue, If(myScrollValue - 1 < Gallery3.TemplateWidth, myScrollValue - 1, 0));

In gallery X Property-
myScrollValue

Thanks

Hi @subharadwaj ,

You can use a Container to include the Gallery, outside of the Container, user a Slider control and Timer to move the coordinates of the Gallery. You can find the details of using Slider control to scroll the Gallery in below video:

Create Customized Horizontal Scrollable Gallery in Power Apps using Slider Control (youtube.com)

And next, you just need to add a Timer to control the value of the Slider control.

OnTimerEnd

UpdateContext({varSliderValue: varSliderValue + 5})

Slider default

varSliderValue

Hello @subharadwaj

I would suggest to play on the default value of your gallery. You can put it to tosmething like

Last(FirstN(_col, myScrollValue)) with _col being what ever you assigned as Items property of your gallery.
