The RecurrenceRule does not have the correct Exceptions when modifying the series. The behavior in Outlook is to clear all exceptions when modifying the series. The behavior in Google Calendar is to consider the exception and modify the recurrence rule accordingly.

Create a recurrence appointment (starts on 20th Feb at 8:00 am, recurring daily), whose recurrence rule will be stored in the database as (Picture 1):

DTSTART:20180220T080000Z
DTEND:20180220T083000Z
RRULE:FREQ=DAILY;INTERVAL=1;BYDAY=MO,TU,WE,TH,FR,SA,SU

Further, I create an exception on 23rd Feb, which changes the start time to 8:15 am. This now, in Addition to inserting a new record for the exception, updates the master's recurrence rule to (Picture 2):

DTSTART:20180220T080000Z
DTEND:20180220T083000Z
RRULE:FREQ=DAILY;INTERVAL=1;BYDAY=MO,TU,WE,TH,FR,SA,SU
EXDATE:20180223T080000Z

So far, so good. Now I edit the master and change its start date to 19th Feb. I expect, that the master keeps the exception for 23rd, but the result is another one. The exception record is kept unchanged as expected! BUT the EXDATE in the master is wrong (Picture 3):

DTSTART:20180219T080000Z
DTEND:20180219T083000Z
RRULE:FREQ=DAILY;INTERVAL=1;BYDAY=MO,TU,WE,TH,FR,SA,SU
EXDATE:20180222T080000Z

There is an OnClientTimeSlotClick event that fires if the user clicks in a single time slot.

If the user clicks in one time slot and drags to select multiple time slots before releasing the mouse button no event is fired.

It would be useful if the existing event was fired in this case, or another event was added to fire in this case.

In firefox, the scheduler adds additional option buttons and checkboxes. 

We'd like to control how simultaneous appointments are displayed. It would be nice if the appointments are shown above eachother, as it were layers with transparancy.

If that's not possible than we'd like to control the placing of the appointments. For example the appointments in order of priority from left to right.

Please provide option in scheduler to freeze rows in randomly

Using the following setup, resize the appointment so that when releasing the mouse, it is over the appointment as demonstrated in the attached video with the attached project.

I am exporting all the appointments using the RadScheduler's Export Calendar functionality (RadScheduler.ExportToICalendar(apptCollection, true)). 

I have the scheduler working with both regular and recurring appointments in my project with RadScheduler along with different timezone for each of the appointments within the scheduler properly. 

However, when I export the same through the above API as an ICS file, I am seeing that the date time is always coming out as UTC on recurring events giving me the wrong results in Outlook. 

Hi,


I used "Telerik Ajax Rad Scheduler" using DLL  "Telerik.Web.UI.dll" version "2014.1.225.40", but i got an error "Failed to load resource: the server responded with a status of 404 (Not Found)" and UI styles are only loaded partially.



I also tried the below mentioned steps  provided on the URL , but it did not work. Please  let me know your thoughts and help me to overcome this scenario

1) https://www.telerik.com/forums/telerik-web-ui-webresource-axd-404-error-not-found

2) https://docs.telerik.com/devtools/aspnet-ajax/general-information/troubleshooting/web-resources-troubleshooting

In http://www.telerik.com/account/support-tickets/view-ticket.aspx?threadid=631805 Plamen indicated a feature request was created to implement CRUD via ODatabinding for the RadScheduler control but I can't find it. Currently it's read-only but we really would like to be able to maintain appointments as well via OData because we already have that API available in our product. This way we don't have to build\maintain a new web service.

When trying to drag and drop an appointment over the All Day slot, the ghost element is not positioned properly. This is easily observed when the browser is zoomed.

WORKAROUND approved by ADMIN: Set the LocalizationPath in the code behind, e.g. in Page_Load event

When the Scheduler is in an initially hidden container, the appearance is broken. 

Solution: call the .repaint() method of the control as soon as the parent becomes visible

Test Environment:

OS: Windows_11

This doesn't work: apt.Description = DescriptionText.Text;
