The timeRangeDoubleClickCallBack() method executes the server-side time range double-click action using a CallBack (ASP.NET WebForms, ASP.NET MVC, Java).
DayPilot.Scheduler.timeRangeDoubleClickCallBack(start, end, resource, data)start (DayPilot.Date) - start of the time range
end (DayPilot.Date) - end of the time range
resource (string) - resource of the time range
data (object) - additional custom data
Use this legacy helper to trigger the server-side time range double-click action manually.
The data parameter lets you include additional custom data with the callback request.
const start = new DayPilot.Date("2026-03-09T09:00:00");
const end = new DayPilot.Date("2026-03-09T10:00:00");
dp.timeRangeDoubleClickCallBack(start, end, "R1", { source: "selection" });
