Weird behaviour and Lag while trying to edit in a Schedule component.

Hi,

I have an implementation of the reach schedule component. There are two problems I am facing:


Problems video: https://drive.google.com/file/d/1baHEzRTI8880NOcDdt1h0pj9biQWuOiR/view?usp=sharing


1) There is a lag while trying to edit the records. I will drag one side to change the timing, but the record will only show changed timing after couple of seconds. To be honest, I don't even mind the lag, if I could add a loading animation or message while the edited records shows up correctly. But I don't know on which event the loading animation should stop. I tried with 'actionComplete' event, but the actionComplete is executed far before the edited record shows up correctly. 


2) As you can see in the video, sometimes while trying to edit the last record, the last two records get mixed up. This bug is not consistent and shows up only some times. Not exactly sure what is causing it.


Adding some code snippets:

Hi Manisha Ghosh,


Greetings from Syncfusion Support,
 

We have thoroughly reviewed and validated the query you reported with your shared details and image screenshot.

Issue 1: There is a lag while trying to edit the records. I will drag one side to change the timing, but the record will only show changed timing after couple of seconds. To be honest, I don't even mind the lag, if I could add a loading animation or message while the edited records show up correctly. But I don't know on which event the loading animation should stop. I tried with 'actionComplete' event, but the actionComplete is executed far before the edited record shows up correctly.

We have checked and validated your video demo. You mentioned that when you resize events, they change from the old time to the new time, and you consider that an issue. However, when you resize events, they rerender, and that rerendering is clearly visible to you, so it’s not actually an issue.

Issue 2: As you can see in the video, sometimes while trying to edit the last record, the last two records get mixed up. This bug is not consistent and shows up only sometimes. Not exactly sure what is causing it.
 

We have thoroughly reviewed and validated the query you reported with your shared details and image screenshot. You mentioned that while resizing an event, two records get mixed up. However, we were unable to replicate the reported issue on our end. Please refer to the shared sample for your reference.


If you are still experiencing the issue, we kindly request the following to help us investigate further:


  1. Share a minimal sample that replicates the problem, or
