Regular expression for validating date of birth

If i want to continue loading and load that record into some error can i do that?

Hello All, On my websites registeration form, I am trying to do a client side validation for users birthday. Total Days/365.25 You can create a custom validator for this

I want to validate if the birthdate entered by user is between current year and past 100 years. NET-Web-Pages-Creating-Custom-Validators Put the following into a C# class file named Birthday and place it in a folder named App_Code (exactly like that) in your root folder: @Mike, Like always thank you for the answer. I have tried several dates between today and 100 yrs ago, but none of them work.

When you are expecting dozens, or even hundreds, of responses in your Google Forms, it is always a good idea to have some rules in place and respondents data should be matched against these rules even before they submit the form.

For instance, if your form is asking for a person’s year of birth, they should only be allowed to enter a number between 19.

For example, checking a valid date of birth, social security number, full name where the first and the last names are separated by a comma, finding number of occurrences of a substring, replacing substrings, date formats, valid email formats, a currency format, and so on. NET, the Regex class represents the regular expression engine. Regular expressions are a pattern matching standard for string parsing and replacement and is a way for a computer user to express how a computer program should look for a specified pattern in text and then what the program is to do when each pattern match is found. They are a powerful way to find and replace strings that take a defined format.

It can be used to quickly parse large amounts of text to find specific character patterns; to extract, edit, replace, or delete text substrings; and to add the extracted strings to a collection to generate a report. In this post, we will learn how to split the string using Reg Ex in C#.

I have removed many codes and shorten my html with only the required codes relevant to this thread.

C# Regex class offers methods and properties to parse a large text to find patterns of characters. A regular expression or regex or regexp is a sequence of characters that defines a pattern.

The field will now accept input value like 1920, 2010 but would reject other values that fall outside the range.

A regular expression may appear gibberish but they aren’t so difficult to read and understand if you can know the basic rules of the language.

You'll likely want to use a Range Validator similar to what oned_gk suggested : Try sumitd answer string str Year = "1998"; string str Month = "4"; string str Day = "5"; Date Time d1 = Date Time. Try entering dates in the following format: yyyy-mm-dd If that doesn't work, double check the code you have htere and compare it to what I posted. That's why the single field validator I created doesn't work for you.
