Hello,

I am using RadScheduler in ASP.NET MVC - WebService binding. I am setting culture in OnLoad event, but this setting is reverted to English culture after some time (usually 2-3s). I observed, that it happens after my SchedulerProvider method GetAppointments(RadScheduler owner) is called, but not sure.
Do You have any clue what is wrong with that?I am stuck on this for a while.

Thank You

Here is my sample code:

    
            <script runat="server">  
        
            protected override void OnLoad(EventArgs e) 
        
                { 
        
                    // Set appropriate culture for calendar 
        
                    RadScheduler1.Culture = CRM.Web.Code.Globalization.GlobalizationManager.CurrentUICulture; 
        
                    // Set first and last day of a week 
        
                    switch (RadScheduler1.Culture.ToString()) 
        
                    { 
        
                        case "en-US": 
        
                            RadScheduler1.FirstDayOfWeek = DayOfWeek.Sunday; 
        
                            RadScheduler1.LastDayOfWeek = DayOfWeek.Saturday; 
        
                            break; 
        
                        default: 
        
                            RadScheduler1.FirstDayOfWeek = DayOfWeek.Monday; 
        
                            RadScheduler1.LastDayOfWeek = DayOfWeek.Sunday; 
        
                            break; 
        
                    } 
        
                    RadScheduler1.ShowAllDayRow = Model.ShowAllDayEvents; 
        
                    RadScheduler1.WorkDayStartTime = Model.WorkDayStartTime; 
        
                    RadScheduler1.WorkDayStartTime = Model.WorkDayEndTime; 
        
                    RadScheduler1.DayStartTime = Model.DayStartTime; 
        
                    RadScheduler1.DayEndTime = Model.DayEndTime; 
        
                    // Export iCalendar 
        
                    SchedulerAppointmentContextMenu.Items[0].Text = "ExportICalendar".GetLocalizedGlobal(); 
        
                    // Delete 
        
                    SchedulerAppointmentContextMenu.Items[2].Text = "Delete".GetLocalizedGlobal();

Hi Jan,

Thank you for sending detailed problem description.

In order for the client-side RadScriptManager globalization to work you must also set the Page culture to be the same as that of RadScheduler:

// Set appropriate culture for calendar

RadScheduler1.Culture = CRM.Web.Code.Globalization.GlobalizationManager.CurrentUICulture;

Page.Culture = RadScheduler1.Culture.ToString();

I hope this helps.

All the best,

Hello Jan,

The custom resource provider factory shouldn't be a problem - it doesn't seem to be used by the ScriptManager at all.

At the moment, I'm still not convinced that the culture is getting set on the client. Can you paste this in the address bar of the loaded page?
javascript:alert(Sys.CultureInfo.CurrentCulture.name);

If it matches your set culture then the problem is somewhere else. The full page source and/or live URL will help us a lot in tracking it down.

Kind regards,

Hello,

You are right, my client culture does not match the culture, which I have set on the server side. It is weird behavior for me. When I try to show the current culture with this code <%= System.Threading.Thread.CurrentThread.CurrentCulture.Name %>, everything is ok and it matches the set culture.

I override the culture in my page declaration (Culture="cs-CZ" UICulture="cs-CZ") and also in OnLoad method and in RadScheduler declaration, but nothing helped.
Anyway, I suppose it´s an error in my code somewhere.
Thank You for Your patient help.

Hello again,

I´m still lost in RadScheduler localization.Thanks to Your help, I found that the problem lies in MicrosoftAjax.js script which is rendered by Telerik_Web_UI_WebResource.
Sys.CultureInfo.CurrentCulture is overriden to "en-US" in this part of the script:
....
if(typeof __cultureInfo==="undefined")var __cultureInfo='{"name":"en-US","numberFormat"
....

My RadScriptManager registration follows:

<telerik:RadScriptManager ID="RadScriptManager1"
    runat="server"
    EnableScriptGlobalization="true"
    EnableScriptLocalization="true"
     >     </telerik:RadScriptManager>

I get "en-US" when I call : javascript:alert(Sys.CultureInfo.CurrentCulture.name);
System.Threading.Thread.CurrentThread.CurrentCulture.Name is "cs-CZ "

I really appreciate any help

Kind Regards Jan

P.s I can give You access to my application in case You will need more information.

Hello Jan,

Apologies for the late reply. I've set the culture on a test page to cs-CZ and this is what I see rendered in the form, right before the MS AJAX scripts are included:

var __cultureInfo =

'{"name":"cs-CZ","numberFormat":{"CurrencyDecimalDigits":2,"CurrencyDecimalSeparator":",","IsReadOnly":true,"CurrencyGroupSizes":[3],"NumberGroupSizes":[3],"PercentGroupSizes":[3],"CurrencyGroupSeparator":" ","CurrencySymbol":"Kč","NaNSymbol":"Není číslo","CurrencyNegativePattern":8,"NumberNegativePattern":1,"PercentPositivePattern":1,"PercentNegativePattern":1,"NegativeInfinitySymbol":"-nekonečno","NegativeSign":"-","NumberDecimalDigits":2,"NumberDecimalSeparator":",","NumberGroupSeparator":" ","CurrencyPositivePattern":3,"PositiveInfinitySymbol":"+nekonečno","PositiveSign":"+","PercentDecimalDigits":2,"PercentDecimalSeparator":",","PercentGroupSeparator":" ","PercentSymbol":"%","PerMilleSymbol":"‰","NativeDigits":["0","1","2","3","4","5","6","7","8","9"],"DigitSubstitution":1},"dateTimeFormat":{"AMDesignator":"dop.","Calendar":{"MinSupportedDateTime":"\/Date(-62135596800000)\/","MaxSupportedDateTime":"\/Date(253402293599999)\/","AlgorithmType":1,"CalendarType":1,"Eras":[1],"TwoDigitYearMax":2029,"IsReadOnly":true},"DateSeparator":".","FirstDayOfWeek":1,"CalendarWeekRule":0,"FullDateTimePattern":"d.

;

If this is on your page, your localization should be working. We'll be able to check this, as well for any other possible issues, if you can indeed grant us temporary access to the live application.

If all else fails and we can't persuade ASP.NET to render it you can just add this in a script tag right after the opening form tag.

I hope this helps.
