OK, I'm sure this is easy for someone but I can't seem to find an answer anywhere. I have a textbox on an asp.net page. I need to make sure that anything written in that box is a decimal between 0 and 1 i.e: .110, .56, .034. Values such as -.99, 1.22, etc are not allowed, nor are alpha characters, a % sign or other non-numeric characters (except the decimal point).
Thanks in advance!
