Help in Regular Expression

[Sandeep Akhare]

Hey Navaneeth the problem here is we can't use asp validator for our application as after firing we are changing the style sheet of controls (in base control) by re rendering its content

I guess this can't be done on a single regular expression. Are you allowed to use a custom JS function, Then you can make use of two expressions and validate it.

Use Trim function and check the length. This will trim white spaces in the both end. You can add whitespace trimming in regular expression too. But I think it will remove the spaces in between the words (Sandeep Akhare)

It's very interesting. Download RegExBuddy. It's a ultimate tool, and it helped me a lot to learn regular expressions.

That's what i am doing finally // Check for blank spaces In both first and last Name fields if (String.IsNullOrEmpty(txtFirstName.Text.Trim())) { this.reqFirstName.IsValid = false; } reqFirstName is my validator derived from custom validator this line of code i am writing in my Pages not in validator then question will be why i have used this validator. i think its not proper implementation of validator Any way thanks for your suggestions and providing me RE tool

^[\w\s,./?;'":`!~@#$%^&*()+=|{}[\]-]{1,500}$ use this for alpha bate,it handle many validation for alphabet in regular expression. first u put this in regular expression validate r and see what happen ofter that arrange this according to ur requirements. and for blank space use required validate r.
