Dear All,

I have created a simple scanning system:

1. Click the respective scan button

2. Scan barcode

3. Scanned data is populated into text input beside the clicked scan button

Need help to create a simpler UX design as per below:

1. Select any text input I want

2. Click scan to scan barcode

3. Populate the scanned data into selected text input

Hope to receive some guidance from this community. Thanks in advance.

Hi @JAWL ,

Set a Variable on the OnSelect of each Text box (example)

UpdateContext({varScan:"to"})

Then OnScan

UpdateContext({varCode:Self.Value})

Then the Default of the Text box

If( varScan = "to", varCode )

Hi @WarrenBelz

I followed your instructions but the scanned data populated in all selected text boxes. Refer to screenshots below:
1. I select Serial Number text box to scan Barcode 123
2. But when I select PN text box to scan another barcode, the "123" auto-populated and the "123" disappears in Serial Number text box.

I want the "123" sticks with Serial Number text box and the "123" will not be auto-populated on the next selected text box. Did I miss anything?

@JAWL ,

I have now gone to the effort of building a model - the problem before was resetting. You need this on the OnSelect of your boxes

UpdateContext({varScanBox: "TO"})
UpdateContext({varScanBox: "PN"})
UpdateContext({varScanBox: "SN"})

On the Scanner OnScan

If( varScanBox = "TO", UpdateContext({varScanTO: Self.Value}), varScanBox = "PN", UpdateContext({varScanPN: Self.Value}), varScanBox = "SN", UpdateContext({varScanSN: Self.Value}) )

And on the text box Default

varScanTO
varScanPN
varScanSN

@warren

I followed your instructions above for the first text box and OnScan. I did for the next text box per below. What should I tweak?
