Globalization of DateTime for Persian

in blazor ui version 2.24.1 I use this code in program.cs for globalization:

public static async Task Main(string[] args)
        {
            var builder = WebAssemblyHostBuilder.CreateDefault(args);
            builder.RootComponents.Add<App>("#app");
            builder.Services.AddTransient(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });

            builder.Services.AddTelerikBlazor();

            // register a custom localizer for the Telerik components, after registering the Telerik services
            builder.Services.AddSingleton(typeof(ITelerikStringLocalizer), typeof(SampleResxLocalizer));

            var host = builder.Build();

            await SetCultureAsync(host);

            await host.RunAsync();
        }

 private static async Task SetCultureAsync(WebAssemblyHost host)
        {
            var jsRuntime = host.Services.GetRequiredService<IJSRuntime>();
            var cultureName =await jsRuntime.InvokeAsync<string>("blazorCulture.get");

            if (cultureName != null)
            {
                var culture = new CultureInfo("fa-IR");

                DateTimeFormatInfo info = culture.DateTimeFormat;
                info.AbbreviatedDayNames = new string[] { "ی", "د", "س", "چ", "پ", "ج", "ش" };
                info.DayNames = new string[] { "یکشنبه", "دوشنبه", "ﺳﻪشنبه", "چهارشنبه", "پنجشنبه", "جمعه", "شنبه" };
                info.AbbreviatedMonthNames = new string[] { "فروردین", "ارديبهشت", "خرداد", "تير", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };
                info.MonthNames = new string[] { "فروردین", "ارديبهشت", "خرداد", "تير", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };
                info.AMDesignator = "ق.ظ";
                info.PMDesignator = "ب.ظ";
                info.ShortDatePattern = "yyyy/MM/dd";
                info.FirstDayOfWeek = DayOfWeek.Saturday;
                CultureInfo.DefaultThreadCurrentCulture = culture;
                CultureInfo.DefaultThreadCurrentUICulture = culture;
            }
        }

when use TelerikDatePicker , id dosenot work properly. the code of my component in here:

<div class="demo-section k-form k-form-vertical">
    <div class="k-form-field">
        <label for="travel-date" class="k-label k-form-label">Travel Date</label>
        <div class="k-form-field-wrap">
            <TelerikDatePicker Min="@Min" Max="@Max" @bind-Value="@selectedDate" Id="travel-date"></TelerikDatePicker>
        </div>
    </div>
    <div class="k-form-field">
        <p>The selected travel date is: <strong>@selectedDate?.ToShortDateString()</strong></p>
        <p>The selected travel date is: <strong>@selectedDate?.ToString()</strong></p>
        <p>The selected travel date is: <strong>@selectedDate?.ToUniversalTime()</strong></p>
        <p>The selected travel date is: <strong>@selectedDate?.ToLongDateString()</strong></p>
    </div>
</div>

@code  {
    public DateTime Max = new DateTime(2050, 12, 31);
    public DateTime Min = new DateTime(1950, 1, 1);
    private DateTime? selectedDate=DateTime.Now;
}

Hello Ali,

It has been a few months since this was opened, and there seems to be no further issue in this particular regard discussed in this thread. So, I am marking this one as "Declined" to keep the portal tidy as it does not seem to relate to an actual bug in the components. If there is new pertinent information or an actual issue, please provide the relevant information and this could be reopened.

Hello Ali,

Have you switched to the Gregorian calendar with translated (localized) strings? Only the Gregorian calendar and Gregorian dates can work correctly with the DatePicker due to the compatibility issues between the two calendars. This is the reason for the offset (incorrect date). 

If you have already switched to Gregorian calendar and Gregorian dates, and there is a problem, please describe it in more detail -

  • explain the meaning of the Arabic strings that you are using in your test scenario
  • describe the current unexpected behavior
  • describe the desired behavior

Hello,

Our Calendar and Date/Time Pickers support the Gregorian calendar only. You can still localize the month and weekday names though.

If you are actually trying to use the Gregorian calendar and the problem is different, please explain in more detail what exactly does not work as expected.
