Resetting Barcode Reader Control

Posted on by CU25110749-0

I building an app for product inspection and in my inspection form I have a datacard for Part Number and I wanted to use BarcodeReader control to scan the barcode and then display the scanned value in the Part number field.

Therefore I am using the below formula in the default property of the the partnumber datacardvalue (Text Input Control)

First(BarcodeReader1.Barcodes).Value
 
However, I want to display the part number field empty in the new form but now it displays the previously scanned part number. 
How can I reset my Barcodereader control?

Hey,

So i would not display the value directly from the Barcode scanner but use an ectra step. Save the value in a variable.

You have the property "OnScan", There you can enter this Formula:

Set(varBarcode,First(BarcodeReader1.Barcodes).Value) //or UpdateContext({varBarcode:First(BarcodeReader1.Barcodes).Value})

You can choose if you never leave the screen when filling out the form you can use UpdateContext otherwise use the Set formula.

UpdateContext is cleare when leaving the screen.

If you use the set function just add after sending or canceling the form this:

Set(varBarcode,Blank())

If this solved your problem, please mark it as Solved to help others find the solution faster.
