I am trying to create a page where i can scan a barcode and the product will be sent into my product list.
I don't know about all barcode scanners, but all the ones I've used just act like an input device like a keyboard.
simply select a control and scan your barcode - the control will be populated with the barcode that has been read.
beyond that, you will need to provide a lot more information about your app for anything more detailed
Like Ajax, in my experience a scanner just provides input. They can be set to sent a Tab or Enter at the end, and you use the before/after update events of a textbox to handle the input (if handling is required).
FYI, I deleted your duplicate thread.
