Editing recurrence events shows wrong dates on the scheduler

These are the issues faced while editing the recurring events:

  • The timezone of the scheduler is Asia/Riyadh, I created the recurring events and the display was correct on the scheduler, but when I edit one event of the recurring events, both the edited event as well as the previous event is shown on the scheduler.
  • I am facing another issue, I need all the events of the scheduler to be displayed in a grid.

Hi Lavita, 

Greetings from Syncfusion Support. 

Q1: We have validated your reported problem and we have prepared a sample and it is working properly at our end. And for further reference kindly refer the below UG link, 

Q2: Based o your requirement, we have prepared a sample using dataBound event and for further reference kindly refer the below snippets, 

    function onDataBound() { 
        var schObj = document.querySelector('.e-schedule').ej2_instances[0]; 
        var gridObj = document.querySelector('.e-grid').ej2_instances[0]; 
        gridObj.dataSource = schObj.eventsData; 
    } 

And for further reference, kindly refer the below index and controller file in the below snippet, 

Code snippet: 
 
Index.cshtml file: 
@using Syncfusion.EJ2 
@{ 
    ViewData["Title"] = "Home Page"; 
} 
<div style="display: flex"> 
    <div> 
        <ejs-schedule id="schedule" width="100%" dataBound="onDataBound" selectedDate="new DateTime(2018, 2, 15)" height="650px"> 
            <e-schedule-eventsettings dataSource="@ViewBag.appointments"></e-schedule-eventsettings> 
        </ejs-schedule> 
    </div> 
    <div> 
        <ejs-grid id="grid"> 
            <e-grid-columns> 
                <e-grid-column field="Id" headerText="Identifiant"></e-grid-column> 
                <e-grid-column field="Subject" headerText="Subject"></e-grid-column> 
                <e-grid-column field="StartTime" headerText="StartTime"></e-grid-column> 
                <e-grid-column field="EndTime" headerText="EndTime"></e-grid-column> 
            </e-grid-columns> 
        </ejs-grid> 
    </div> 
</div> 


<script> 
    function onDataBound() { 
        var schObj = document.querySelector('.e-schedule').ej2_instances[0]; 
        var gridObj = document.querySelector('.e-grid').ej2_instances[0]; 
        gridObj.dataSource = schObj.eventsData; 
    } 
</script>

        { 
            ViewData["Message"] = "Your contact page."; 

            return View(); 
        } 

        public IActionResult Error() 
        { 
            return View(new ErrorViewModel { RequestId = Activity.Current?.Id ?? HttpContext.TraceIdentifier }); 
        } 
    } 
} 

Kindly try the above code snippet, if the issue still persists in at your side, kindly share the scheduler rendering code/image/video demo/running sample(if possible) for the better serve.

Thank you for your response.

 

I have another issue. I have installed Syncfusion.EJ2.AspNet.Core 17.4.0.49 version in my application. I am using the following in Layout: <script src="https://cdn.syncfusion.com/ej2/dist/ej2.min.js"></script> and material.css.

The issue I am facing is my code runs as expected locally but when I run it on server I am unable to save the edited recurring event. This happens only when I edit recurring event. The error I found in the console are as follows:

SCRIPT5007: Unable to get property 'StartTime' of undefined or null reference

1.        SCRIPT5007: SCRIPT5007: Unable to get property 'contains' of undefined or null reference

2.        SCRIPT5007: SCRIPT5007: Unable to get property 'getTime' of undefined or null reference

Thank you for your response. 
I am working on  Asp.net core 3.0 version.I have attached the document with screenshot of the error I get when I edit a recurring event and click on save. This issue is only in the live environment and for recurring event. 
Locally everything works as expected.

Thank you for your response. 
I am working on  Asp.net core 3.0 version.I have attached few related code and view with screenshot of the error I get when I edit a recurring event and click on save. This issue is only in the live environment and only for recurring event. Index.cshtml is the view and scheduledata.cs contains the models I use. 
Locally everything works as expected. 
 


HB Hareesh Balasubramanian Syncfusion Team February 21, 2020 12:27 PM UTC

Hi Lavita, 

Thanks for the update. 

We have validated your shared code snippets and we suspect that you have maintained the events for the scheduler locally which could be the cause, if you are using UrlAdaptor for the scheduler kindly maintain the appointments in DB. So, the CRUD actions will works properly. 

And for further reference, kindly refer the below UG link, 

Kindly try the above UG link and if you still face the issue please let us know. We awaiting to serve you better. 

Regards, 
Hareesh 


LA Lavita February 28, 2020 06:58 PM UTC

Thank you
I am not saving the data locally. Its saved in the DB. The thing is CRUD operation works fine for the non-recurring events, but only when editing recurring event I  am facing this issue, all the other operations work fine for the recurring event.


PG Pon Geetha A J Syncfusion Team March 2, 2020 11:20 AM UTC

While debugging the code I found the starttime and endtime format as given below 
 
 
 
And also the data is getting loaded continuously as you can see the number of request is 5844 as shown below 
 
 
 
Could you help me out with this?
