    Hi Jeevan,

    You need to use a regular expression to validate. A good site to test RegEx with a library of examples is regex101.com. You can test your expressions against a test list of inputs live which helps a lot. 

    In this case, I was able to create the following that only allows alphabetic characters, does not allow spaces, only allows a capital letter as the first character, and makes sure the string is 3-25 characters long (the 2,24 below is for the character validation after the first letter):

    ^[A-Z]([A-Za-z]){2,24}$

    I tested this in my environment and it validates correctly.

    Thanks,
    Mike
