I’m trying to figure an effective way of handling multiple barcode scan events. I have an embedded view containing a text field + button. What I want to happen is the button is pressed, the camera reads the barcode and the text field displays the scanned barcode. If there is only 1 instance of that embedded view, I can return the value via message handler or in a custom session property, then bind the text field there. However if I’m placing the embedded view in a flex repeater, how would I go about getting the barcode value sent to the correct text field? I do have a unique identifier as a parameter on the embedded view, but I can’t bind the barcode scan context property to that id. Similar to this: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/0/c087b66e5e1cd3863f42d0f956ec696fc6e9b605.png) Any ideas would be appreciated! ---

Never mind found a work around. Double up the script event of the button to save the identifier in session.custom in a script, then the scan barcode. Then from there when the barcode scanned session event is fired, you can read back the above and pair the barcode value with the identifier. ---

Thanks for sharing your solution @stevenson 🙂 Exactly what I searched the forum for. Works like a charm! 👌🏼 ---

Stevenson, do you mind sharing screenshots of what you did? I’m confused from your solution. ---

Here’s my button for a barcode scan: First script: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/4/f449dc20730718baf252e5b3ef04c09ca02608e3.png) Scan barcode: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/9/3931891ff608258b8995afdeb52231505fccceff.png) Session Handler: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/3/f37303a15a00ad1d8359f66ebbd10476b1fe6a14.png) “Barcode1” can be replaced with any unique identifier to handle multiple scan events and fields. From there the text field showing the scan value can just be bound to `session.custom.Barcode.Scanned[]` Hope this helps! ---

you’re amazing, thank you so much! Just a quick question. Would this way of setting up the barcodes allow me to connect specific barcodes to specific tags? ---

I don’t see why not. You could have a change event script on the session.custom.Barcode object that would write the newly scanned barcode to a tag. ---

Thank you again, I really appreciate it!
