Alex that is perfect.  Thanks very much to you and Andrew.

Hello,

please fix all links to localization.

THX.

Any news about calendar localization? Suggested links are broken.

I'm updating localization programmatically:

  dte.Language = XmlLanguage.GetLanguage("it-IT");

but Today field doesn't get translated and it's still using english date format.

Thank you. Bye!

Hello,

You can add the following code after the InitializeComponent():

 Infragistics.Windows.Editors.Resources.Customizer.SetCustomizedString("TodayButtonCaption", "Oggi: {0:d}");

in order top chage the Caption of the "Today" button.

Hope this helps you.

Hello Stefan,
thank you for your suggestion.

I'm currently using these two lines of code:

    dte.Language = XmlLanguage.GetLanguage("it-IT");
    Infragistics.Windows.Editors.Resources.Customizer.SetCustomizedString("TodayButtonCaption", "Oggi: {0:d}");

where, of course, both the language code (it-IT) and today's translation are variables that depend on user's language selection.

Everything works ok, except for the dates that are being shown, both in calendar field and in today's date suggestion. I would like to translate only calendar's strings, not date format: it should follow Regional Options that are currently active on the machine.

For example, my current regional settings are Italian, with this date format: dd/MM/yyyy.
This is what happens if user selects a language:

1) Italian: everything is displayed in italian (strings all lower case!) and dates are showed using Regional Options format. Ok.

2) English: everything is displayed in english (strings have the first letter in uppercase) and dates don't follow Regional Options (they're using english format, MM/dd/yyyy).

So... how to translate only strings?
Thanks again, bye!

Thank you for pointing me to the right direction.
I solved with this row:

editor.FormatProvider = Thread.CurrentThread.CurrentCulture;

since Format property has no effect while you're in edit mode.
Thanks for your assistance, bye Maria

Hello Maria,

You set XamDateTimeEditor's Format Property to a static value like this: 

xamDateTimeEditor1.Format = "dd/MM/yyyy";

or you can set it to the machine format like this:

xamDateTimeEditor1.Format = Thread.CurrentThread.CurrentUICulture.DateTimeFormat.ShortDatePattern;

Hope this helps you.

Stefan,
step by step, we are finally coming to a solution! :)

I've modified my code, in order to apply your last suggestion:

 dte.Language = XmlLanguage.GetLanguage(sLangCode); Infragistics.Windows.Editors.Resources.Customizer.SetCustomizedString("TodayButtonCaption", sToday + ": {0:" + Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortDatePattern+ "}");

Now a little sample with these two lines of code.
With a combo, the user can select the language of the application. When a language is selected, the application loads, showing all the strings in the choosen language, and using the current Regional Options to display date and time values.
Here you can see, respectively, English, Italian and French selections (the current date is yesterday, 11th december 2012, and Regional Options are Italian): 

Everything is ok, except for the date that is being shown on English calendar. This reveals that the field is not using Regional Options that are currently active. Probably, because when I set calendar's Language property, all locale's settings are modified and not only the labels' translation.

Anyway, thanks a lot for your help so far!
Bye, Maria 

Hello,

You can use the following code in order to use the Regional Options:

CultureInfo ci = (CultureInfo)Thread.CurrentThread.CurrentUICulture.Clone();
ci.DateTimeFormat.SetAllDateTimePatterns(new string[] { "dd/MM/yyyy" }, 'd');

Thread.CurrentThread.CurrentUICulture = ci;

Thread.CurrentThread.CurrentCulture = ci;

Infragistics.Windows.Editors.Resources.Customizer.SetCustomizedString("TodayButtonCaption", "Oggi: {0:" + Thread.CurrentThread.CurrentUICulture.DateTimeFormat.ShortDatePattern + "}");

If your ShortDateFomat is already set to dd/MM/yyyy you can skip the first 4 lines.

Hope this helps you.

Thank you,
but I would like date format to follow Regional Options settings, both in calendar and today fields.
For details, see my post above.

Have a nice day!
