Custom header with server-side grid config


I’m configuring grid server-side because on the client I don’t know how many columns there will be at runtime.

I have a timestamp column and I want to put two text boxes with pop-up calendars in a custom header for this column. So users can filter by selecting a start and end date/timestamp.

Any tips on how to do this server-side?


Unfortunately there is no any ready to use samples of such functionality.
