Cell background set in BeforeCellRender but not show for whole scheduler

Are you using the latest DayPilot version?

Something like this can happen:

1) if the Scheduler height is detected incorrectly (this may happen if the parent element is hidden during the Scheduler initialization) or

2) if it is initially rendered with a smaller height which is increased later

#1 - the latest version detects the hidden parent automatically and fixes the Scheduler when it becomes visible

#2 - recently, there was a bug that prevented the Scheduler from detecting window resizing correclty; this should be fixed in the latest release as well

You can also refresh the Scheduler manually by calling .show() on the client side (JavaScript):

dp.show();

Where "dp" is the value of ClientObjectName.

Hi Dan,
I am using latest version 8.1.3461.1 but the issues still reproducible.
It may regard to the height issues on DayPilot scheduler.
As i put DayPilot inside the Telerik RadPane, RadSplitter and the height is maybe not known that time.
To solve this, I put in a little trick DayPilotScheduler.setScrollX(1) and DayPilotScheduler.setScrollX(-1) in javascript.
After this little bit of code, it can show the background cell color correctly.
May I know is that any drawback/issues of using this code in javascript? It shouldn't be performance issues right?
Thanks.
