Hello Team,

I am developing a QR Code application. I have a QR Code, for example: qr.abc.com/c73ffd8b-293f-4144-ae28-a110525c734c .

I have a list containing Machine Number, Material Type, Material Density, Model, UID. Please find the screenshot of the list below:

The QR Code is same as the UID.

I have my application. Find a screenshot below:

The issue is, when I scan the QR Code (qr.abc.com/c73ffd8b-293f-4144-ae28-a110525c734c), it should automatic fill in the datacard (UID) and based on the field UID, it should autofill the values for other datacards as well. I think we should use a function called lookup.

Can you please give me a solution.

If you are using display form as your connector then you can set up the DataSource as Filter(YourDataSource, UID = uidfromscannedqr)

Then the remaining data cards just select accordingly ThisItem.MachineNo and so on.

Hello .. The code is correct, but the values are not autofilled in the data cards.

1. I have put this code on the edit form of the screen.
2. On each datacardvalue (text input), i have put the following code in the default property.

3. On "OnScan" property of the QR Code, I did not add any code.

Can you please give me a solution so that I can see the values.

@sahilauzim ,

From what I can see, you have the default values referring to a data source, not the record/values from the scanned code, so firstly do you also want to display these saved values after you have scanned ? You could set a Variable OnScan of the barcode reader

UpdateContext( { varQRCode: LookUp( 'QR Code List', UID = First(Self.Barcodes).Value ) } )

then the Default (example)

Coalesce( varQRCode.'Material Type', TheItem.'Matrial Type' )

so it will show the scan code if present or the data source field if not. Note that this approach requires resetting the variable (Screen OnVisible would be a good start)

UpdateContext({varQRCode: Blank()})

Firstly have a look at what is in varQRCode after you scan. Put a label on the screen with

varQRCode.UID

I feel it is a problem with the barcode reader, because currently I cannot parse the barcode normally when I put the formula in onscan.
