Asp button click event fire while HTML check box dynamically created pressing enter key

Seriously, nobody can help you fix a problem we can't see in code we can't see running on a system we can't access.

Click the green "Improve question" link and update your question to include the relevant parts of your code, the relevant parts of the code you've tried, and a clear and complete description of what you are trying to do and where you are stuck.
