Capture OnSelect of Barcode Scanner Control

Posted on by pTaunk

Barcode scanner control only has these two properties:

OnScan – Actions to perform when a barcode is successfully scanned.

OnCancel – Actions to perform when a barcode scan is canceled by the user.

We want to capture a third scenario when the scanner control is clicked ( before the OnScan is triggered). Usually the button control in PowerApps has OnSelect function which is missing from this control. Do you have any idea on how can we achieve that.

Hi @pTaunk ,

Yes, barcode scanner do not have a OnSelect property , but I have a workaround for your reference:

1\Add an other button and set it's OnSelect property to:

Select(BarcodeScanner1); YourOnSelectedEvent;

2\Set the barcode scanner control's visible property to:

false

Doing so is equivalent to using your newly created button as an initiator for the barcode scanner, and it also has the OnSelect property.

Best Regards,

Bof

Hi @v-bofeng-msft ,

Thank you. This worked perfectly for my use case. This is a simple and effective solution that I was trying to over engineer.
