RadScheduler: MinutelyRecurrenceRule is not parsed correctly


I am using CalHelper to convert recurrence rule to and from string.

It looks like when I convert rule to string and then parse it back to recurrence, some of the properties get dropped.

Please see below from my VS editor highlighting this:


Am I doing something wrong, or is this a bug?

Hi, Anu,

The CalHelper.RecurrenceRuleToString method returns an incomplete string representation of the recurrence rule which can't be completely parsed by the CalHelper.TryParseRecurrenceRule method later. If you want to extract the recurrence rule to text and then parsed the rule back, the appropriate method is CalHelper.RecurrenceRuleToStringEx.

            MinutelyRecurrenceRule rule1 = new MinutelyRecurrenceRule();
            rule1.Interval = 15;
            rule1.Start = DateTime.Today.AddDays(1);
            rule1.End = DateTime.Today.AddDays(2);  
            string rule1String = CalHelper.RecurrenceRuleToStringEx(rule1);

            RecurrenceRule rule2;
            CalHelper.TryParseRecurrenceRule(rule1String, out rule2);  

            Appointment a = new Appointment(DateTime.Now, TimeSpan.FromMinutes(10),"A1");
            a.RecurrenceRule = rule1;

            Appointment a2 = new Appointment(DateTime.Now, TimeSpan.FromMinutes(10), "A2");
            a2.RecurrenceRule = rule2;

I have approved this item in order to avoid any further confusion which method to be used.

I have also updated your Telerik points.

If you need any further assistance please don't hesitate to contact me.
