US vs UK datetime/string format failing on certain machines. Ideas

[adolf garlic]

I'm having a problem with dates.
(No not the sort that you have at christmas)

I have a webform with a text box and a calendar control.
You can either
- enter a date manually (we are talking uk style here dd/mm/yyyy) in the
textbox
- click a date on the calendar which puts the date value in the textbox (uk
style)

pointing a browser at my machine this works fine
pointing at the UAT and production machines it falls in a heap with the
error shown below

I've asked our admin to check and he says everything is configured to be uk
where possible

This is for an intranet app so i'm not bothered about time zones and all
that crap.
i've seen a bunch of postings where people are using
datetime.parse( xx,formatprovid er) with all sorts of bits and pieces
and some of the formatting things are crazy
5 or 6 lines of code just to format something from a text box

i thought asp.net was supposed to make you more productive with fewer lines
of code!

why am i getting the error?
is there any file on the servers in question i can change to make it work?

also

all of the other date values on the screen (when using the other servers)
are shown using US date format

can anyone shed any light on this?

thanks!

I have a webform with a text box - enter a date manually (we are talking uk style here dd/mm/yyyy) in the Does this work on all machines?
- click a date on the calendar ... (uk style) Is the problem that putting the date converts it to mm/dd/yyyy ?

What is you Culture and UICulture in the web.config - if it's not set it'll
be en-US

<configuratio n>
<system.web>
<globalizatio n
culture="en-US"
uiCulture="en-US"
....

you can set the culture by code to

System.Threadin g.Thread.Curren tThread.Current Culture =
System.Globaliz ation.CultureIn fo.CreateSpecif icCulture("en-US");
System.Threadin g.Thread.Curren tThread.Current UICulture =
System.Threadin g.Thread.Curren tThread.Current Culture;
