Help Cycling Through Gallery or SharePoint Items

[Aurora]

Hi All, 

My company has an app that tracks quality issues with parts we manufacture. When a quality issue is frequent enough, we create a "Quality Alert" that is displayed in the workshop for builder to see. Where I need help is:

We would like to have our quality app "Cycle Through" all of the quality alerts. Currently, I have a gallery that shows data for each quality alert and am wondering if there is a way to set a timer and have the gallery change the "selected Item" after a certain duration. We often include images with the quality alerts, So I have to be able to provide a section with a large enough image for our floor workers to see. I have a working image viewing component, So I know if I'm able to change the selected item, I can display that Items image. I'll include an image of what I have so far, though its basic so far. 

Any suggestions on where to start or what to do would be greatly appreciated. 

If I can have the app automatically change the selected gallery item, this layout should work.

Hi,

Reading your question the teleprompter came to time. See if you can adapt it to your need.

Power Teleprompter v2 - Power Platform Community (microsoft.com)

Should it work, here's the author's linkedin: Hardit Bhatia | LinkedIn

Hi @Aurora ,

The recently introduced Index() function should be of use here:

https://docs.microsoft.com/en-us/power-apps/maker/canvas-apps/functions/function-first-last

If you initialize a variable (varIndex) to 1 and then use buttons to increase (display next item) or decrease (display previous item).

For this you need to set the Item property of your form to:

Index(YourDataSource, varIndex)

The Next button should have the following OnSelect property:

Set(varIndex, If(varIndex+1 > CountRows(YourDataSource),1,varIndex+1)

Likewise the Previous button should have the following Onselect property:

Set(varIndex, If(varIndex-1<1,CountRows(YourDataSource),varIndex-1)

Hi @BCBuizer,

After some initial testing, I think this will work. Thank you for the help!
