The eventClickCallBack() method invokes the server-side click handler using an AJAX callback.
This only applies to ASP.NET WebForms, ASP.NET MVC and Java versions.
DayPilot.Scheduler.eventClickCallBack(e, data)e (DayPilot.Event) - target object
data (object) - additional custom data sent to the server-side event handler
This is a legacy server-side helper for ASP.NET WebForms, ASP.NET MVC, and Java Scheduler integrations.
Use the data parameter to include custom values with the callback request.
const e = dp.events.find(1);
dp.eventClickCallBack(e, { source: "custom-button" });
