[Solved] Week numbers is wrong

[Jan Mucha]

Hello, I found the problem of the week numbers in calendar. Numbering is not correct. Current week number is 1 greater than the reality.

Hi Jan,

By default RadCalendar does not apply week numbers according to the ISO standard, because the ASP.NET framework itself does not do this.

In order to make RadCalendar apply week numbers according to the ISO 8601 standard, please use the approach demonstrated below:

<%@ Page Language="C#" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">

    protected void Page_Load(object sender, EventArgs e)
    {
        System.Globalization.CultureInfo c = new System.Globalization.CultureInfo(RadCalendar1.CultureInfo.ToString());
        c.DateTimeFormat.CalendarWeekRule = System.Globalization.CalendarWeekRule.FirstFourDayWeek;
        RadCalendar1.CultureInfo = c;
    }

</script>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
<title>RadControls for ASP.NET AJAX</title>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" />

<telerik:RadCalendar ID="RadCalendar1" runat="server" FirstDayOfWeek="Monday" />

</form>
</body>
</html>

All the best,
Tsvetina
