Retrieve Weeknumber

Neil posted over 12 years ago

How can I retrieve the week number for a selected date based on the week rule property? I've been through the documentation and intellisense and cannot find anything that works.

Thanks.

Hi nhutchinson,

this should be working:


    <title></title>
    <script language="javascript" type="text/javascript">
// <![CDATA[

        function Button1_onclick() {
            var wmc = $find('WebMonthCalendar1');
            var selectedDay = wmc.get_selectedDate();
            var days = wmc.get_days();
            var weekNumber;

            for (var i = 0; i < days.length; i++) {
                if (days[i].isSelected()) {
                    weekNumber = days[42 + Math.floor(i / 7)].get_weekNumber();
                }
            }
        }

// ]]>
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <ig:WebScriptManager ID="WebScriptManager1" runat="server">
        </ig:WebScriptManager>
        <ig:WebMonthCalendar ID="WebMonthCalendar1" runat="server" SelectionType="Single"
            OnSelectedDateChanged="WebMonthCalendar1_SelectedDateChanged" WeekRule="FirstFourDayWeek"
            EnableWeekNumbers="true">
        </ig:WebMonthCalendar>
    </div>
    </form>
    <p>
        <input id="Button1" type="button" value="button" onclick="return Button1_onclick()" /></p>
</body>
</html>

The get_days() returns array of visible days-cells in calendar, where first 42 items represent days. If application enables week numbers, then following 6 items represent week-number cells.
The properties of days and week numbers are different. For example, month-days have get_day/month/year/dow and other methods like isSelected/isWeekend/isFocus, but they are not week-numbers and that property and returns -1. The week numbers on other hand, do not have day-related properties and those methods return -1. But they have get_weekNumber. So, if application wants to check week-number displayed by a row where a month-day is located, then it may use following: weekNumber = days[42 + Math.floor(i / 7)].get_weekNumber();
