CompareValidator problem

Axel Dahmen

Hi,

I've got the same problem as described below. No answer found yet. Can
someone please help? (I'm using .NET 1.0 on my development machine and 1.1
on my webserver. Like Susanna, I only get the error on my webserver.)

TIA,
Axel Dahmen

I used compare validator control "ValueToCompare" in my aspx file like
this:

<asp:comparevalidator id="CompareValidator1" runat="server"
CssClass="image-caption" ValueToCompare="500,000.00"
Operator="LessThanEqual" Type="Currency" ErrorMessage="Tast inn et
tall som ikke er høyere enn 500000!" Display="Dynamic"
ControlToValidate="txtLaneSum" Text=""></asp:comparevalidator>


And it works fine on my development server. but when I have installed
this .NET application to the production server, I can not get the
ASP.NET page to work. I am given an error message as the following:

Server Error in / Application
The value '500,000.00' of the ValueToCompare property of

The current culture of the web form is used to convert from the string
"500,000.00" to a decimal value. If that culture treats "," as a decimal
place and period as a thousands separator (like many countries do), you will
get that error. Most likely your server is setup with a different default
culture than your development computer.

See the System.Globalization.CultureInfo object documention for an overview
of cultures.

See the <@ Page Culture= > attribute for setting a culture on one page.
You can also set the culture in the current thread:
System.Threading.Thread.CurrentCulture = [your CultureInfo object]

Hi, Peter,

unfortunately this is not the case. I have this problem with both, English
as well as German formatted prices. In the meantime I've found out that my
webserver converts SQL SMALLMONEY values into decimal values having a 4
digit precision. This value irritates the Validator. Here's an exact
description of the problem:
http://www.gotdotnet.com/Community/MessageBoard/Thread.aspx?id=214327

Any help is quite appreciated!

TIA,
Axel Dahmen

Be sure to do any number to string conversion using the same CultureInfo
object used by validators. That would be in
System.Threading.Thread.CurrentCulture.

For example, do convert a decimal value in 'val', pass the culture in
ToString()

decimal val = 32.12;
string vFormattedVal = val.ToString(System.Threading.Thread.CurrentCulture)

If this is the correct answer, may I recommend you post a solution to your
thread on gotdotnet so others involved know the results.

Thanks, Peter,

actually the correct answer would be that my webserver converts val into a
string having a precision of 4 digits. If you pass 32.12 to val, ToString()
yields "32.1200". The Validator is not able to convert this value into a
Currency value because of the two trailing zeros.

I've set the correct culture in Page_Init() so the culture is not the
problem here. After changing val.ToString() into val.ToString("F2")
everything works fine. However, one question remains: Why does my
development machine convert 32.12 into "32.12" whereas my webserver converts
it into "32.1200"...

I've posted my solution to GetDotNet. Still I'm curious how I can force my
webserver to behave like my development computer and vice versa. As long as
they behave differently I can't avoid missing errors during testing and
debugging.

regards,
Axel Dahmen
