If I have a field which is supposed to take only ‘number’ data. How can I prevent user from entering any character ? I read about validation but its not working in my case.
Instead of displaying that entered character is invalid. I want to prevent user from entering wrong character. (Something like a field supposed to take only number wont take any char i.e nothing will be displayed if user enters a char). Is it possible…?
IF not how does that ‘rules’ work ? Does it display any message later ?
