Catch event when Expanding/Collapsing Resources in Scheduler.

Hello,
Is there a way to know when the user Expands or Collapses the Resources in the Scheduler?
I want to be able to catch the event so I can update some data.
Thank you.

Hi Leonardo, 

Greetings from Syncfusion support. 

We have validated your reported query “Is there a way to know when the user Expands or Collapses the Resources in the Scheduler?” at our end. We have to let you know when we performing the Resource Expand and Collapse operation, the actionBegin event is triggered. So, we can update the data in the actionBegin event of the Scheduler like the below code. We have prepared a sample for your reference and it can be available below. 

[Index.razor] 
@{ 
    if(ExpandCollapse != null) 
    { 
        <em><p>@ExpandCollapse</p></em> 
    } 
} 
 
<SfSchedule TValue="TimelineResourceView" SelectedDate="@CurrentDate" Height="550px"> 
   <ScheduleEvents TValue="TimelineResourceView" OnActionBegin="OnActionBeginEvent"></ScheduleEvents> 
</SfSchedule> 
 
@code{ 
    public DateTime CurrentDate = new DateTime(2020, 8, 26); 
 
    public string ExpandCollapse; 
 
    public async void OnActionBeginEvent(ActionEventArgs<TimelineResourceView> args) 
    { 
        string[] RequestArray = { "resourceCollapse", "resourceExpand" }; 
        if (Array.IndexOf(RequestArray, args.RequestType) > -1) 
        { 
            ExpandCollapse = args.RequestType; 
        } 
    } 
} 


Kindly try the above sample and get back to us if you need any further assistance.

Hi Ravikumar,

Thank you that worked.

I have another question, is there a way to know exactly what resource we're clicking?
The event doesn't seem to have this information.

Thanks
