I am making a device management app that is connected to a sharepoint list. I attached a barcode scanner to the home screen and asset lookup screen in the search bar. I can open the barcode scanner and scan a barcode but then it just goes back to the screen it was already on. These barcodes are already in the sharepoint list. how do I tell the barcode scanners to lookup the barcode in the sharepoint list and return the item in said list?

Re: power app Barcode scanner lookup and return value

If('Device List',Subtitle1=BarcodeScanner1.Value,Navigate('Device Details',ScreenTransition.Cover);If('Device List',Subtitle1,Not(BarcodeScanner1.Value,Navigate('Edit Device'))))
This is the strand I have for the onscan category. I am trying to tell the barcode scanner to go to the item in the device details screen with the corresponding serial number and if it does not have a corresponding serial number then go to the edit device screen so that I can make an item with that serial number. Subtitle 1 is where the serial number is on the device list screen where I am looking up the serial number.

Re: power app Barcode scanner lookup and return value

Hi @dsjordan，

Do you want to retrieve value from list based on barcode scanner value?

Could you please share a bit more about your scenario?

You should have some display controls like TextInput, once the barcode scanner scan a device, each TextInput control will be populated with the item corresponding to the barcode scanned.

Set the TextInput Default property as below:

LookUp(ListName,DeviceBarcodeColumn=BarcodeScanner1.Value).Column1

Note that DeviceCodeColumn is the column you save the barcode, the Column1 is where you want to display the returned item based on the barcode.
