Bar Code Scanner for dropdown input value

(0) Share

Report

Posted on by EvaAGarcia

I have a PowerApp with dropdown values from a SP List; I have several cards that have dropdown values based on the first dropdown value. I would like to set up a scan button for the main dropdown input value, but still have the other dropdowns work with the scanned text input value. I hope this makes sense.

Example: SAP Equipment # populates FAA & Pump Name and other fields from a SP List.

Would like to scan SAP Equipment # and still populate the other fields.

Thanks for the assistance.

Hi @EvaAGarcia
Change the visible property for the Camera and Barcode Scanner control. In this case, I have a combo box named "ComboBox1"
BarcodeScanner and Camera Visible property is

ComboBox1.Selected.Value="Critical"

In this example, both are visible when combo box value is "Critical"

We can set it DisplayMode as well.

I finally have time to work on this scan feature. I'm not quite following what you have instructed.
In your example is "Critical" your column name?

Hi @EvaAGarcia

The previous one was to display the scan button based on the dropdown value. In that case, "Critical" is the choice value.

Get Data based on Scanner Value
We have 2 options based on the scan value using the scanner.

1. Display individual data (Without form)
Set the onscan property of the scanner

Set(ScannedRecord, LookUp(DataSource,Barcode=Value(BarcodeScanner1.Value)))

Set the label control to display FAA and pump Name

FAADataCard.text = ScannedRecord.FAAColumnName PumpNameDataCard.text = ScannedRecord.PumpNameColumnName

For Dropdown, Set the Default property as
ScannedRecord.ChoiceColumnName.Value

2. Display data on the form (Edit form)
Set Item property of Form as

LookUp(DataSource,Barcode=Value(BarcodeScanner1.Value))

and Datasource as SPListname or any data source
