Validate regular expresion - TextField

[Kaido]

Hi,

I had a problem with the regex property of the TextField.

If I do:

<ext:TextField ID="txtDiscount" Width="120" runat="server" Regex="[1][0][0]|[0-9]{1,2}(\.[0-9]{1,2})?"  RegexText="Invalid format" />

the validate is incorrect.

I've tried to do the next:

<ext:TextField ID="txtDiscount" Width="120" runat="server" />


<asp:RegularExpressionValidator ID="RegularExpressionValidator1" ControlToValidate="txtDiscount" ValidationExpression="[1][0][0]|[0-9]{1,2}(\.[0-9]{1,2})?" runat="server" ErrorMessage="Invalid format"></asp:RegularExpressionValidator>

and it found correcty.


I hope It cans be useful.

Best wishes.

Can you give me a couple examples of values you would like to accept?

[Kaido]

Sure,

the regular expresion must be validate a range [0-100]

For example:

100, 25.50, 64, etc...

An incorrect value:

100.36, 45454, etc...

I would use the following:

<asp:RangeValidator runat="server" ... MaximumValue="100" MinimumValue="1" Type="Currency" />

Cheers,
Timothy

Thank you for your reply, Timoty, but I don't want use an asp control because all controls of my page are coolite controls.

I use the property with other regular expresion (e-mail format, time format, etc...) and found correctly but I don't know why this regular expresion fail.

I used the asp:regularExpresionValidator control only to try if it was correct or not.

Hmm, looks to be like your regular expression was missing some stuff:

<ext:TextField ID="txtDiscount" Width="120" runat="server" Regex="^(100|([1-9][0-9]{0,1}(\.[0-9]{2})?))$"  RegexText="Invalid format" />

Works for me.

If you're dealing with currency, the following might be helpful, see http://forums.ext.net/showthread.php...-1.aspx#bm4991

Thanks, Timothy and geoffrey.mcgill.

I apologize for the trouble. I've forgotten to indicate the start condition with the "^" symbol.

But I don't understan why it's happening because by means of
others ways (asp validation controls, regex library, etc...) the previous regular expresion founds correctly. Is coolite more strict?





Thanks a lot :)

[Timothy]

Hello Kaido,

I would say that Coolite and ExtJS are using the regular expressions properly, and not that they are strict. I think Microsoft ASP.NET regular expressions are a little "candy coated" for first time regular expression users, so they will easily forgive you if you're missing your ^ $ characters ;)

Hope this all worked out for you.

Cheers,
Timothy

Hi, Timothy

You're absolutely right :) From now on, I will never forget to specify this characters.


Thank you so much ^^
