Clear Barcode Scan so default Gallery items show

I am new to powerapps and I have created a very simple app. It is a sharepoint list that you can search by scanning a barcode. When you scan the barcode the gallery shows the item in the gallery. All I want to do is create a "Clear" button that when you tap it clears the barcode scan so you see all the items in the gallery again. Can someone please tell me how to do this simply?

It appears the gallery is being filtered using some variable called ODATA__dlc_BarCodeValue.  Can you please try putting this code in the OnSelect property of your Clear button?

Set(ODATA__dlc_BarCodeValue,"")

 

If its a Context Variable you might need to do this instead.

UpdateContext({ODATA__dlc_BarCodeValue: ""})

Thanks for the reply, but that did not work. The clear button did nothing.

Hi @KittyBreath ,

Do you want to clear up the BarcodeScanner1 value when you click the "Clear" button?

 

Based on the needs that you mentioned, I think the Reset function could achieve your needs. I have made a test on my side, please consider take a try with the following workaround:

Set the OnSelect property of the "Clear" button:

Reset(BarcodeScanner1)

 

Or

Set the OnSelect property of the "Clear" button to following:

Set(IsReset, false);Set(IsReset, true);

Set the Reset property of the Barcode Scanner control to following:

IsReset

 

Please consider take a try with above solution, check if the issue is solved.

Thanks for your reply. I had tried the 1st option you gave previously and the clear button did nothing. I just tried your second option and at least the clear button did clear the selection but it just left the gallery blank rather than going back to having the initial list of items in it.

You could just enable Clear on your search box and hit the X to clear the scan to return it to the default items.

 

It sounds like what you're looking for.

Thanks for the reply, however I am not talking about a search bar. The x you are referring to only applies to a text input. I have a barcode scanner I am trying to clear after the scan.
