Hello Team, hope you are doing well.

I'm currently developing a QR Code application. I have 4 datacards namely: ID, Material Type, Material Density and title

i have used powerAutomate to generate QR-Code each time a row is created on my list. This one is working well.

For example I have: ID=2, Material Type=baw, Material Density=dnl and title is HD786. The QR-Code generated is 2bawdnlHD786

The issue is, I am not able to autofill the datacards after scanning the QR-Code on the application.

The code i have use on OnScan property of the barcode reader button is:

UpdateContext({varbarcode:Self.Barcodes});

And the code for one of the text input of the datacardvalue is :

First(varbarcode).Value

Can you please help how can i autofill each datacards with their corresponding values

Thank you ...

Hi @sahilauzim ,

If you run this OnScan

With( {_Code: First(Self.Barcodes).Value}, UpdateContext( { varBarcode: { ID: Value(Left(_Code,1)), Type: Mid(_Code,2,3), Density: Mid(_Code,5,3), Title: Mid(_Code,8,5) } } ) )

then the values you need should be varBarcode.ID, varBarcode.Type, varBarcode.Density, varBarcode.Title

@sahilauzim ,

Please re-check - I amended the code shortly after I posted it.

working good.. but it is static
But in fact, I want it to be dynamic so that it takes the exact values for each field same as on the list.
For example, it will display the values on each datacard based on the ID for each row.

Can you please help?

@sahilauzim ,

Sorry but I am unclear what you want to do here and what do you mean by static ? Those values will update on each scan and just need to be the Default of the relevant controls that will write them to the data source.

Hello ...
What i mean is, for each datacard, the value is not the same. Please find the screenshots below.

I will explain in details what I have done so far.
1. I used powerAutomate to create QR-Code each time a new item is created on my list. Please find the screenshot.

2. When a row is created, a QR-code is generated.

3. The code i have use for the 'bar-code reader' - Property - OnScan

4. on each datacard (text input), on default property, i have used
- varBarcode.Title
- varBarcode.Type
- varBarcode.Density

5. When I scan the QR-Code on my mobile

The output is not the same as the item I created on my list.

I hope this provides you with insight into where I may be making mistakes.

@sahilauzim ,

I don't think the code is a mistake based on what you have posted - the barcode seems to have a pipe | symbol separating some elements which is not what I based my code on.
