Custom context menus in ASP RadScheduler disappear after AppointmentContextMenuItemClicked

I build custom context menus at runtime for each appointment. The menus work fine, I get the AppointmentContextMenuItemClicked event and am able to act on the menu option chosen, but the UI drops all of the custom menus. The next time I right-click on any appointment, it only has Edit and Delete options. I've tried Rebind() at the end of the AppointmentContextMenuItemClicked, but it does not refresh, and even if I call databind and step through the code where it reconstructs all of the menus, they still do not show up in the browser. Anyone dealt with this?

Appointment is invalid and Cannot Read Property errors for Scheduler in Chrome 61

*** Update from 17 Jan 2018 ***

The problem discussed below has been fixed in R1 2018 (2018.1.117).

*** End of update ***

The new Chrome 61 introduces some breaking changes which may lead to some of the following errors when the browser is scrolled and the resize handler of an appointment is clicked:

Uncaught TypeError: Cannot read property ‘viewPartIndex’ of null

Sys.WebForms.PageRequestManagerServerErrorException: Appointment Start time must be before the End time

Uncaught TypeError: Cannot read property 'cells' of undefined

Uncaught TypeError: Cannot read property 'resizeFromStart' of null

Uncaught TypeError: Cannot read property 'intervalIndex' of null;

Solution:

Placing the following JavaScript override before the declaration of the Scheduler should resolve all of the above issues:

<script type="text/javascript">

Telerik.Web.UI.RadScheduler.prototype._compensateScrollOffset = function(contentTable) {

//In Chrome and Safari document.documentElement.scrollTop is always 0, due to a browser bug

//In Internet Explorer there is no "document.scrollingElement"

var scrollingElement;

if ($telerik.isSafari || $telerik.isChrome) {

scrollingElement = document.body.scrollTop <= document.scrollingElement.scrollTop ? document.scrollingElement : document.body;

}

var bodyOffsetElement = scrollingElement ? scrollingElement : document.documentElement,

bodyScrollOffset = $telerik.getScrollOffset(bodyOffsetElement, false),

scrollOffset = $telerik.getScrollOffset(contentTable, true);

scrollOffset.x -= bodyScrollOffset.x;

scrollOffset.y -= bodyScrollOffset.y;

contentTable.targetRect.x += scrollOffset.x;

contentTable.targetRect.y += scrollOffset.y;

// The Safari issue here could be a problem in getLocation (used in getBounds). This code offsets it

//if($telerik.isSafari3 || $telerik.isSafari4 || $telerik.isChrome)

//{

// contentTable.targetRect.x += scrollOffset.x;

// contentTable.targetRect.y += scrollOffset.y;

//}

}

</script>

If any other issues are observed in Chrome 61+ environment, please share them along with more details and specific examples of the reproduction steps so we can update the information here.

Is there a way to iterate through each group by Resource item?

I would like to set some attributes to each group by item when binding the scheduler with appointments, filtered by some criterion.

My aim is to ultimately access this attribute via the DOM to then do further logic.

E.g.

'VB.Net

schedule.GroupBy = "FoodType"

'Other code...

Private Sub schedule_ResourceGroupByItemDataBound(sender As Object, e As EventArgs)

Dim group = e.Item

group.Attributes.Add("data-foodtypeid", group.Value)

End Sub

// Example case on the client

function schedule_Load(sender, args) {

$("schedule [data-foodtypeid='1']").hide();

}

4.5 radscheduler doesnt work with service

Just use the radscheduler scenario for a service and it works inserting detailed info via 4.0, but with 4.5 .net it gets the following error:

(How do I get around this??)

(also - I notice 4.5 doesnt display any tooltip type message liek 4.0 does, and if I type somehting in the simple form subject and hit options, in 4.0 it carries what I typed to the options screen, but 4.5 does not - something is disconnected??)

Rebind/ Refresh RadScheduler on closing RadWindow

Hi,

I have a custom edit form. I open it up by setting OnClientAppointmentEditing="OpenEditSchedulePopup".

In my page I have some dropdownlists which are used to filter the data in the RadSchedule. I use a RadAjaxManager so that when the dropdown selection is changed the RadSchedule is updated via Ajax.

I would like to get the same effect when the Custom Edit Popup is closed. I have noticed that when the standard edit form is closed it uses Ajax to rebind the RadScheduler. How do I get my custom Edit popup form to use ajax to update the radscheduler when it is closed?

The standard edit form is doing it so I am sure it is possible.

.net 4.5 radscheduler doesnt work

I use this sample:

https://demos.telerik.com/aspnet-ajax/scheduler/examples/advancedformtemplate/defaultcs.aspx?_ga=2.107659522.1423900032.1612185078-422710438.1602686251

It works fine.

I upgrade to .net 4.65 (and use the .45 version of the control)

When you go to the advanced form and save - it just sits there forever.

I posted another issue that I THOUGHT was just with a service, looks like thats not the case. Looks like scheduler 4.5 version simply does not work. This is in latest and back to 2019 Q1 version (I dont have any earlier than that)

Expanding recurrence in C# instead of using SQL UDF.

Hello!

Is there possibility to expand RecurrenceRule in C# instead of using SQL UDF (provided here: http://www.telerik.com/community/forums/aspnet-ajax/scheduler/sql-reporting-display-all-recurring-appointments.aspx)?

For example I have List of type Appointment and I want to expand Recurrences in elements which have RecurrencyRule != null so the result will be List of upcoming events ordered by Start attribute.

Is this possible?

Thanks in advance

EDIT:

I've opened ExpandRecurrence_UDF zip file from post about SQL UDF and I've found function which returns occurences for RecurrenceRule string but when I try to parse my RecurrenceRules which are being parsed by SQL UDF function I can't get this make to work under C#.

Function:

    
                    public static IEnumerable ExpandRecurrence(string recurrenceRule, DateTime rangeStart, DateTime rangeEnd) 
        
                    { 
        
                        List<OccurrenceInfo> occurrences = new List<OccurrenceInfo>(); 
        
                        RecurrenceRule rrule; 
        
                        if (RecurrenceRule.TryParse(recurrenceRule, out rrule)) 
        
                        { 
        
                            rrule.SetEffectiveRange(rangeStart, rangeEnd); 
        
                            foreach (DateTime occStart in rrule.Occurrences) 
        
                            { 
        
                                OccurrenceInfo info = new OccurrenceInfo(occStart, occStart.Add(rrule.Range.EventDuration)); 
        
                                occurrences.Add(info); 
        
                            } 
        
                        } 
        
                        return occurrences; 
        
                    }

Occurences class:

    
            public class OccurrenceInfo 
        
            { 
        
                private DateTime start; 
        
                private DateTime end; 
        
                public OccurrenceInfo(DateTime start, DateTime end) 
        
                { 
        
                    this.start = start; 
        
                    this.end = end; 
        
                } 
        
                public DateTime Start 
        
                { 
        
                    get { return start; } 
        
                    set { start = value; } 
        
                } 
        
                public DateTime End 
        
                { 
        
                    get { return end; } 
        
                    set { end = value; } 
        
                } 
        
            }

Sample RecurrenceRule string which I'm tryign to parse:

    
            RecurrenceRule.TryParse("DTSTART:2008422T000000Z\nDTEND:2008423T000000Z\nRRULE:FREQ=YEARLY;INTERVAL=1;BYMONTHDAY=22;BYDAY=MO,TU,WE,TH,FR,SA,SU;BYMONTH=04\n", out rrule)

I've tryed to use Replace function to convert \n to Environment.NewLine but it was returning false too.

EDIT2: I've found bug in my RecurrencyRule string. Month in DTSTART and DTEND was in X format (for months 1-9) instead of XX
