expression validator

[cmrhema]

Hello
I am using a text box where I want the user should input only alpha numeric values.
I tried to used regular expression validator
In the validation expression I wrote a-z,A-Z,0-9
But it does not work

Where am I wrong

Thanks Rohit
I have changed it to
^[a-zA-Z0-9]{8,8}$

So now the textbox will be vaildated for alphanumeric values also the length of the password should be only 8(neither more nor less)

One more question while browsing many a websites, I have noticed that when the user inserts any character(non alphabet and non numeric such as *,,>% etc)
It displays * not allowed.

for eg i have keyed in a * than it would prompt * not allowed
if i keyed in % than it would prompt % not allowed

Any idea what kind of validator should i use and where
