The eventClickPostBack() method invokes the server-side click handler using a PostBack.
This only applies to ASP.NET WebForms.
DayPilot.Scheduler.eventClickPostBack(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 Scheduler integrations.
Use the data parameter to include custom values with the PostBack request.
const e = dp.events.find(1);
dp.eventClickPostBack(e, { source: "custom-button" });
