View 1 RepliesWeb Forms :: Regular Expression For Empty TextBox
Nov 20, 2010I am using regex for server side validations.
I am facing a problem with regex. I want to check for sepecial characters like ><*&()%$@!~+...
I need to filter these special charecters...but the problem is in my 10 textboxes there only 3 are required...
I can submit the form without entering anything...but my regex is not allowing me to submit the form without giving a space from keyboard...
I just want to check for special charecters and empty textbox without giving a spacebar...
I just check these sites(http://regexlib.com/ and http://www.regular-expressions.info/) and read some documentation on regex...its kind of confusing....
Here is my regex for Middlename: ^[a-zA-Z''-'s]|[ ]{1,40}$ its worked but its not correct....then I changed it to ^[a-zA-Z''-'sd*]{1,40}$ this also not taking emptytextbox without giving a space...
My Goal:
In most of the textboxes I need to allow only numbers and - # _ in some textboxes....
For Address: need to allow alphabets and numbers and #-_' "
City: numbers and alphabets no special chars...
Main problem is I can write regex for most of these stuff but need to all textboxes without entering anything (empty textboxes).My work got stoped due to this.
