Hi,
 
     We tried the examples given in the Telerik site for RadCalendar and implemented Localization for the same successfully. But, it works only for the Culture \ CultureInfo properties (like "en-US", "fr-FR") for both RadScheduler and RadCalendar. But, in our application we are using only "CurrentUICulture", which has the value of only neutral culture (like en, fr etc ...) . When this is assigned to the RadCalendar, we are getting the following error:

Message: Culture 'fr' is a neutral culture. It cannot be used in formatting and parsing and therefore cannot be set as the thread's current culture.
Stack trace:
   at System.Globalization.

CultureInfo.CheckNeutral(CultureInfo culture)
   at System.Globalization.CultureInfo.get_DateTimeFormat()
   at Telerik.Web.UI.Scheduler.Views.Month.RendererBase.CreateNavigationPane(Control container)
   at Telerik.Web.UI.Scheduler.Views.Month.Renderer.GetContent()
   at Telerik.Web.UI.RadScheduler.CreateContent()
   at Telerik.Web.UI.RadScheduler.CreateChildControls(Boolean bindFromDataSource)
   at System.Web.UI.Control.EnsureChildControls()
   at System.Web.UI.Control.FindControl(String id, Int32 pathOffset)
   at Telerik.Web.ChildControlHelper.FindControlRecursive(String ID, Control root)
   at Telerik.Web.ChildControlHelper.FindControlRecursive(String ID, Control root)
   at Telerik.Web.ChildControlHelper.FindControlRecursive(String ID, Control root)
   at Telerik.Web.UI.RadAjaxControl.OnPagePreRender(Object sender, EventArgs e)
   at System.EventHandler.Invoke(Object sender, EventArgs e)
   at System.Web.UI.Control.OnPreRender(EventArgs e)
   at System.Web.UI.Control.PreRenderRecursiveInternal()
   at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)


But, as per the information given in the link below, the 'CultureInfo' property should also support the two letter ISO Language names like "en" or "fr" etc ..  
     http://www.telerik.com/help/aspnet-ajax/p_telerik_web_ui_radcalendar_cultureinfo.html

Can you please let us know a solution for this ? How can we assign the 'CurrentUICulture' (TwoLetterISOLanguage Name) value to the 'RadCalendar' control, which has only the 'CultureInfo' property ?

Thanks & Regards,
Karthik.

Hi,

The problem is that a Thread's culture can not be neutral. It must be specific like en-US or fr-FR. Give this suggestion a try and let me know how it goes.

Hello Pavlina,

I don't see a suggestion to try.  Would you post the suggestion to try as I'm having this same issue.  Thank you.

Hi David,

The suggestion of Pavlina applied with code will look in a similar way:
<telerik:RadCalendar ID="RadCalendar1" runat="server" CultureInfo="fr-FR"></telerik:RadCalendar>

You can find more details on how to localize RadCalandar in the following article:
