Barcode scanner to checkbox

(0) Share

Posted on by geoUPA

Hello,

My app behaves as an equipment inventory, with functionality for checking in and checking out items. The Check In and Check Out pages are galleries with checkboxes for each item, as well as a dropdown menu and search bar for filtering. When an item's checkbox is toggled on, the OnCheck property collects to a Google sheet the name of the item, whether it's being checked in or out, and who is interacting with the item. Everything on that end works as it should.

I also have a barcode scanner functionality, which can scan an item's physical barcode, and immediately sticks the serial number in the search bar. Once the serial number is in the search bar the gallery automatically filters to find the corresponding item. What I would LIKE to happen here is once the gallery filters for the correct item, it also automatically toggles the checkbox on -- rather than the user manually checking the box.

Is this something that I can accomplish? Here is a screenshot of the check in gallery and the screen once a barcode is scanned and filtered.

Hi @geoUPA ,
On the end of the code set a Variable
UpdateContext({vChecked:true}); Reset(CheckBoxName)
Make the Default of the Checkbox
If( vChecked, true, false )
You will need to reset the Variable onscreen exit (and entrance would be safe as well)
UpdateContext({vChecked:false});

Please click Accept as solution if my post helped you solve your issue. This will help others find it more readily. It also closes the item. If the content was useful in other ways, please consider giving it Thumbs Up.

Sorry @WarrenBelz , set a variable for which control?? This doesn't come naturally to me.

I set the variable (set(oncheck, vchecked) in the oncheck control
And put the (UpdateContext({vChecked:true});Reset(Checkinbox)) in the barcode onscan control
And set If(vChecked,true,false) in the checkbox default

Still no dice.

Hi @geoUPA ,
As long as the action (OnScan) triggers the variable set (as below) ,this should definitely work - try it with a button and then see what has to trigger it.

@WarrenBelz

So it is successfully checking the box onscan, however it is now checking all the boxes. Is this an issue with my updatecontext({vchecked: false})?

OK @geoUPA ,
I did not realize you had these in a gallery and there were multiple. So I assume the barcode is somewhere in the data of the gallery display item?
I will use the names in blue - BarCodeNo for the field & ScannedCodeNo for the code scanned - change to your actual names.
In the Reset of the CheckBox,
If( vChecked && ThisItem.BarCodeNo = ScannedCodeNo true, false )

Hi @WarrenBelz

Unfortunately the checkboxes are still all being ticked. Any other ideas?

Hi @geoUPA ,
Yes you cannot reset a control from outside the object, but strangely it works for me with an error showing in design mode. However if you reset the gallery instead of the checkbox, it works as below.
