    Regexps cannot detect null values. They only work with strings. You might have meant empty string.

^d*$ will match any input value that is either empty or composed solely of digits. Alternatively D will match any input value that has at least one character that is not a digit. For example, in Javascript:






console.log(/^d*$/.test(''));

console.log(/^d*$/.test('123'));

console.log(/^d*$/.test('x1'));

console.log(/D/.test(''));

console.log(/D/.test('123'));

console.log(/D/.test('x1'));

    Your solution does not work for you because the ^[D]$ pattern matches a string that only contains a single char other than a digit. Note that [ and ] can be safely removed as character classes only make sense when they have multiple chars/char ranges in them.



    I suggest



    [RegularExpression(@"^D+$", ErrorMessage = "Input can have no digits.")]
    
public string FirstName { get; set; }


    The @"^D+$" pattern only matches a string that has no digits in it. Note that RegularExpressionAttribute patterns should always match the whole input, so ^ and $ anchors are good to use here.

      Nov 20 '18 at 7:57











    • @AsifShakir If you need to show error if the input is empty, use [Required]. There is no reason for you to want to avoid it.

      – Wiktor Stribiżew
      Nov 20 '18 at 7:58













    • @WiktorStribiżew yeah you are right . But any possible way to check empty string with this pattern ?

    [Required(ErrorMessage = "{0} cannot be empty")]
    
[RegularExpression(@"^[a-zA-Z]+$", ErrorMessage = "{0} must have Alphabets only")]
    
[Display(Name = "First name")]
    
public string FirstName { get; set; }


    Error message if the input is empty:




    First name cannot be empty




    and if the input value contains non alphabet character(s):




    First name must have Alphabets only





    If you want to allow empty value, you could try:



    [RegularExpression(@"(^$)|(^[a-zA-Z]+$)", ErrorMessage = "{0} must have Alphabets only")]


    (^$) allow an empty string. Then, if it's NOT empty, continue to check with the pattern (^[a-zA-Z]+$) (alphabet characters only).

    • Without using [Required] how i dont Allow empty string with Regex pattern.

      – Asif Shakir
      Nov 20 '18 at 8:44











    • @AsifShakir In that case, you just need [RegularExpression(@"^[a-zA-Z]+$", ErrorMessage = "{0} is not valid.")]. This is not allowed an empty string and non alphabet characters with the error message: First name is not valid.

            @TânNguyễn In answers, "does not work" means "does not work for OP". Edited the wording in answer.

            @AsifShakir If you need to show error if the input is empty, use [Required]. There is no reason for you to want to avoid it.

            [Required(ErrorMessage = "{0} cannot be empty")]

[Display(Name = "First name")]
            
public string FirstName { get; set; }


            Error message if the input is empty:




            First name cannot be empty




            and if the input value contains non alphabet character(s):




            First name must have Alphabets only





            If you want to allow empty value, you could try:



            [RegularExpression(@"(^$)|(^[a-zA-Z]+$)", ErrorMessage = "{0} must have Alphabets only")]


            (^$) allow an empty string. Then, if it's NOT empty, continue to check with the pattern (^[a-zA-Z]+$) (alphabet characters only).

            • @AsifShakir In that case, you just need [RegularExpression(@"^[a-zA-Z]+$", ErrorMessage = "{0} is not valid.")]. This is not allowed an empty string and non alphabet characters with the error message: First name is not valid.

            How to change which sound is reproduced for terminal bell?

            Image
            3 Recently upgrade to 18.10 from 18.04, and using the terminal is becoming annoying: the new alert sound is a drip ( /usr/share/sounds/gnome/default/alerts/drip.ogg ), and the previous one is still located at ( /usr/share/sounds/ubuntu/stereo/bell.ogg ). My issue is that at the gnome-terminal, when autocompleting or pressing left BOTH sounds are reproduced, at the same time. I want to just have ubuntu/stereo/bell.ogg active, not both . At the moment I have been only able to reduce the volume of the alerts (but still both are played), or turn the alerts down (but I dislike both "solutions"). gnome-terminal 18.10 teminal-bell share | improve this question ...

            Can I use Tabulator js library in my java Spring + Thymeleaf project?

            0 I want to add Tabulator js to my java project. I added tabulator.min.js, tabulator.min.css to resources folder.

            Title Spacing in Bjornstrup Chapter, Removing Chapter Number From Contents

            Image
            up vote 5 down vote favorite 2 I would like to make it so that the vertical space below the title of each chapter is the same when using the Bjornstrup package (i.e. so that the descenders do not affect the spacing - as shown by the red arrow in the picture below). I think I'm fairly happy with the spacing around "A chapter", so I'd really like titles without descenders (e.g. "Contents") to have the same vertical spacing as "A chapter" below the title. I would also like to remove the large "0" in the contents title. Any help appreciated, as always. documentclass[11pt,a4paper]{book} % Packages[![enter image description here][1]][1] usepackage[left=3.5cm, right=3.5cm, top=4.3cm, bottom=4.25cm]{geometry} usepackage[utf8]{inputenc} usepackage{libertine} usepackage[libertine]{newtx...
