Hi All,

I am writing validation for an email address. First off, i want to make sure
there isn't a problem using 2 RegularExpressionValidator's for one field....

Other than that this is what I have, the first works fine, but the second,
where I'm trying to exclude ":", I can't figure out the syntax....

<ASP:textbox id="email" Text="" size="32" runat="server" />
<asp:requiredFieldValidator id="ValRequired1" runat="server"
ControltoValidate="email" Display="dynamic">* You must enter an Email
Address.</asp:requiredFieldValidator>
<asp:RegularExpressionValidator id="ValRequired2" ControlToValidate="email"
Display="Dynamic"
ValidationExpression=".+[@].+[.].+"
runat="server"> <br>*Invalid Email Address
</asp:RegularExpressionValidator>
<asp:RegularExpressionValidator id="ValRequired3" ControlToValidate="email"
Display="Dynamic"
ValidationExpression=".+[^:].+"
runat="server"> <br>*Can Not Contain /:,;
</asp:RegularExpressionValidator>

I have also tried...
".*[^:].*"
"[^:]"
"[^\:]"

Thanks
Rel

PS> my next step will to be sure to exclude "/", ";" and ","

how do you exculde more than 1 character with 1 expression?

It seems like you want to match so that all characters in the string
cannot be ':'

The bracket's let you define a set of characters that can match, e.g.
[a-z] or [12345]. If you put an ^ in the front, it will match anything
that is not one of the characters - e.g. [^a-z] will match any character
that is not between a and z (lowercase).

I believe the syntax for what you want is:

[^:]*

To list all three characters you'd do something like:

[^:;,]*

And adding slash in there may work as:

[^:;,/]*

Or you might have to escape the backslash:

[^:;,\/]*

Hope some of that's useful.

Kirk
