How to get Recurence Rule Object from Recurence Rule String

[Rahul]

Hello


We are storing recurrence rules string in appointment table. Now we need to generate recurrences for the rule stored in appointment table.  We try to create object of recurrence rule with the examples found in your forum by passing the RecurrencePattern  object as in posted code below but it gives an error of having no such constructor. is there any other way to get recurrences for recurrence rule string.

Appointment fitnessAppointment = new Appointment();
fitnessAppointment.Subject = "Fitness";
fitnessAppointment.Start = DateTime.Now;
fitnessAppointment.End = DateTime.Now.AddHours(2);

RecurrencePattern recurrencePattern = new RecurrencePattern();
recurrencePattern.Frequency = RecurrenceFrequency.Weekly;
recurrencePattern.MaxOccurrences = 30;
recurrencePattern.DaysOfWeekMask = RecurrenceDays.Monday | RecurrenceDays.Wednesday | RecurrenceDays.Friday;

RecurrenceRule recurrenceRule = new RecurrenceRule( recurrencePattern );

fitnessAppointment.RecurrenceRule = recurrenceRule;


we are using this code but gives an error that no such constructor is available for this class.



Thanks

Hi rahul,

Here is a snippet that should give you an idea:

RecurrenceRule parsedRule;
RecurrenceRule.TryParse(recurrenceString, out parsedRule);

We are converting from another calendar control to the telerik scheduler.  We have historic appointments that are stored in separate fields in the database (frequency, maxoccurrences, interval, etc).  We need the ability to display these old appointments in the new telerik scheduler.  In order to do this we need to convert the data from the database into the telerik recurrence string.  We would like to use the code below.

RecurrencePattern recurrencePattern = new RecurrencePattern();
recurrencePattern.Frequency = RecurrenceFrequency.Weekly;
recurrencePattern.MaxOccurrences = 30;
recurrencePattern.DaysOfWeekMask = RecurrenceDays.Monday | RecurrenceDays.Wednesday | RecurrenceDays.Friday;

RecurrenceRule parsedRule;
RecurrenceRule.TryParse(recurrenceString, out parsedRule);

In the code above how can I get the recurrenceString?

Hi Michael,

Here is a sample code how the recurrence rule can be added to an appointment:

RecurrenceRule newDayly = new DailyRecurrenceRule(interval, range);
      newAppointment.RecurrenceRule = newDayly.ToString();

You can also refer to the Populating the Recurrence rule help topic.

Hope this will be helpful.
