(Monday) FirstDayOfWeek

[arjen]

I made changes to get CultureInfoCurrentCulture.DateTimeFormat.FirstDayOfWeek the first day of the week (for The Netherlands: Monday):

telerik.common.js:

firstVisibleDay: function (date, value) {
    var firstVisibleDay = new $t.datetime(date.year(), date.month(), 0, date.hours(), date.minutes(), date.seconds(), date.milliseconds());
    while (firstVisibleDay.day() != value) {
        $t.datetime.modify(firstVisibleDay, -1 * $t.datetime.msPerDay)
    }
    return firstVisibleDay;
},

telerik.calendar.js:
firstDay = 1 (Monday), I dont know how to use CultureInfoCurrentCulture.DateTimeFormat.FirstDayOfWeek in javascript

var firstDay = 1;
for (var i = firstDay; i < firstDay + 7; i++) {
    html.cat('<th scope="col" abbr="')
        .cat($t.cultureInfo.abbrDays[i % 7])
        .cat('" title="')
        .cat($t.cultureInfo.days[i % 7])
        .cat('">')
        .cat($t.cultureInfo.days[i % 7].charAt(0))
        .cat('</th>');
}
html.cat('</tr></thead><tbody>');
var currentDayInCalendar = $t.datetime.firstVisibleDay(viewedMonth, firstDay);

Calendar.cs:

BuildWeekHeader:

            int firstDay = (int)CultureInfo.CurrentCulture.DateTimeFormat.FirstDayOfWeek;

            for (int day = firstDay; day < firstDay + 7; day++)
            {
                row.Children.Add(renderer.HeaderCellTag(CultureInfo.CurrentCulture.DateTimeFormat.DayNames[day % 7]));
            }


BuildMonthView:
            int firstDayOfMonthView = DateTime.DaysInMonth(prevMonth.Year, prevMonth.Month) - ((int)(prevMonth).DayOfWeek) +
(int)CultureInfo.CurrentCulture.DateTimeFormat.FirstDayOfWeek;

Hello arjen,

Unfortunately choosing FirstDayOfWeek is not supported for the time being. Similar request is logged in our PITS, where you can vote for it.

Nevertheless the current votes, our goal is to implement this functionality for the next official release of the Telerik Components for ASP.NET MVC.

Kind regards,

Hello Georgi,

Its was not a question but some code donation (changes in Telerik source code) to make the calendar culture compliant.
My apologizes if it is the wrong place or not appreciated to donate some code.

Regards,
Arjen

Hello Arjen,

Thank you for the code snippets and sorry for the misunderstanding.

We will further develop given idea in order to cover all possible scenarios. Unfortunately we will not be able to use the given code snippets directly in Calendar UI component.

in PITS it has status RESOLVED, but I don't see this feature in 2010.3.1318 build.
I am quite uncertain about what was fixed?
For me Monday as a first day is working in calendar, but doesn't work in date picker
Please advise

Hello arjen,

Check this online demo, which shows that the FirstDayOfWeek works as expected.

Hello Rafael,

FirstDayOfWeek is connected with current culture. In other words if the culture is en-US, then the first day of week will be Sunday. You can observe this behavior in the demo which was linked in my previous message.

If you need to show first day of week to be not related with the current culture, then you will need to set it manually with overriding $.telerik.cultureInfo.firstDayOfWeek:

<% Html.Telerik().ScriptRegistrar()

                .OnDocumentReady(()=>{

                  %>

                         $.telerik.cultureInfo.firstDayOfWeek = 1; // thus the first day of week will be Monday.

                  <%

                })

                .Render();

%>
