I have a problem where I need to see if the textbox entry is an alphanumeric value. The format for this entry Character(A-Z) then Number(0-9), where there’s only one alphabet and Numbers can be as many as he wants.The lphabet should always come first.A minimum of 2 characters have to be entered.
Example is A100, A1.
It should not accept 1A.
The above means, starting at the beginning of the string, one character in the set A_Z, followed by one or more characters in the set 0-9, followed by the end of the string.
