I want to validate a text box that doesn’t accept any special characters using regular expressions. It just takes letters and numbers from 0 to 9. Please provide me the correct regex.

I want to validate a text box that doesn’t accept any special characters using regular expressions. It just takes letters and numbers from 0 to 9. Please provide me the correct regex.
This should do it:
^\w+$ or ^\w*$
This matches all letters (upper and lower), numbers and underscores.
If you don’t want to match underscores try:
^[a-zA-Z\d]+$ or ^[a-zA-Z\d]*$
