Reset TextInput Default Barcode Reader value in Gallery

Posted on by BenceGyori

Hello!

I'm building an app where the user can take in assets, the quantity of which is dynamic.

The assets fill a Gallery, which has a TextInput control and a BarcodeReader control. The TextInput Default value is the last Value of the BarcodeReader.Barcodes table. This way, the TextInput gets filled properly, but the scanned values don't reset even after navigating to another page and back. This is my problem, because in case of ~50 assets, the user has to manually clear all ~50 TextInputs.

Things I have tried (and didn't work):

- Storing the scan in a variable and making it Blank on reset (using variable caused every TextInput to overwrite its value on every scan)

- Storing the scan in a collection and clearing it (same as previous)

- Resetting entire Gallery control (resets TextInputs with manual value, but not the ones with scanned values)

- Navigating to another page before resetting (still no reset on scans)

Can anyone please provide a solution, or at least an idea?

Thanks!

Edit: Grammar.

hey @BenceGyori

you need to call the Reset(Textinput) for every text input control separately

either onselect of a button or onvisible of screen

Let me know if my answer helped solving your issue.

If it did please accept as solution and give it a thumbs up so we can help others in the community.

Hello, @mmbr1606!

Thank you for your answer, but unfortunately it didn't resolve the issue.

I am using a Gallery, so there is only one editable TextInput, which already has it's value being reset on leaving the screen. The problem is that the TextInput successfully resets, but the Bardcode Reader's table containing the previous scans doesn't reset and I can't make it to do so. As I mentioned, I tried saving it to a variable and making it Blank() on reset, but since in that case the TextInput (and with that, all the TextInputs in the Gallery) have that variable on Default value, the next time the user scans something, all of the Gallery's TextInputs get that last scan as Default value.

I have a Form in the same app, where this "Last scan to variable and Blank to reset" method works just fine, but not here, with a Gallery control. I am asking if there is any method to make it work, or am I trying to accomplish something which Power Apps doesn't have a solution for?
