RadSchedulerRecurrenceEditor does not persist the Selected month in YearView

RELATED TO:

Description 


In YearView of the RecurrenceEditor, when you postback the page, the dropdowns for selecting the month change their value back to the default value (January). 

This change may cause you to lose the selected month in the recurrence rule.

Explanation


The selected values of the dropdowns rely on the StartDate property of the RecurrenceEditor. This value is set by the Scheduler when the RecurrenceEditor is integrated in the Advanced form because it is taken from the appointment.

Solution


When using the RecurrenceEditor as a stand-alone control, the StartDate property should be set manually on postback:

<asp:label text="text" id="Label1" runat="server" />
<telerik:RadSchedulerRecurrenceEditor ID="RadSchedulerRecurrenceEditor1" runat="server"></telerik:RadSchedulerRecurrenceEditor>
<telerik:RadButton ID="RadButton1" runat="server" Text="RadButton" OnClick="RadButton1_Click"></telerik:RadButton>

protected void Page_Load(object sender, EventArgs e)
{
    if (RadSchedulerRecurrenceEditor1.RecurrenceRule != null && RadSchedulerRecurrenceEditor1.RecurrenceRule.Pattern != null)
    {
        var rrule = RadSchedulerRecurrenceEditor1.RecurrenceRule;
        RadSchedulerRecurrenceEditor1.StartDate = new DateTime(
                rrule.Range.Start.Year,
                (int)rrule.Pattern.Month,
                1);
    }
}
