Fire an event automatically after barcode scanner input

Question

I have a textbox on an asp.net page. I use a barcode scanner to get the barcode number into that textbox. I need to then automaticaly fire an event directly after the text box recieves that input. the only event that is exposed is the TextChanged event which doesnt achieve what i need. I am using c# for the code behind.

Regards

Solution

Use TextChanged event with AutoPostBack=true.

Also ensure that your scanner sends a carriage return after scanning(normally with scanning a code from the manual).
