Hi Team,
As attached below image, it is possible to display multiple custom parent control value in asp.net webforms.
You can set the content of the grid cells using BeforeCellRender (see also https://forums.daypilot.org/question/5098/can-we-assign-value-to-parent-control-in-daypilotscheduler1).
You can also add special rows to the bottom and use them to display totals but please note that frozen rows are only supported in the JavaScript version: https://doc.daypilot.org/scheduler/frozen-rows/
