Hi everyone.

I am struggling with the problem resetting value in text input from barcode reader in gallery.

In my app, I created a button for adding new blank row in gallery.

And in the gallery, it consists of barcode reader and text input to show the value.

When I press the button adding new row, the text input is fine.

But adding another row, the text input is not blank. It contains the value the same as the first row.

Even if I create a clear button, it still shows that value when I press adding new row.

I search for solutions and try them to my app for weeks but still doesn't work.

Hi Nandit,

I have tried your method and it works!

I don't have to reset the text input.

Thank you so much and so sorry for replying to you late.

Hi CU24100400-0,

I think you should keep the Barcode Reader outside the gallery and update the ScanningMode property to "Scan Multiple". you can then add a gallery to the screen with the following in the Items property:

BarcodeReader1.Barcodes

Put an Input Box inside the gallery and that's it. Whatever you will scan will keep getting added to the Gallery.

Hope this helps,

Kind regards,

Nandit
