I used a concept of taking a length of the input field and restrict the numbers and symbols as a first character but it doesn't work out. Can some one help me by using pipe concept to allow only a alphabet as a first character.
Thanks in advance

You can use regular expression, like:
^[a-zA-Z][a-zA-Z0-9.,$;]+$?Explanation:
^Start of line/string.[a-zA-Z]Character is in a-z or A-Z.[a-zA-Z0-9.,$;]Alphanumeric or.or,or$or;.+One or more of the previous token (change to * for zero or more).$End of line/string.The special characters I have chosen are just an example. Add your own special characters as appropriate for your needs. Note that a few characters need escaping inside a character class otherwise they have a special meaning in the regular expression.
I am assuming that by "alphabet" you mean A-Z. Note that in some other countries there are also other characters that are considered letters.
