Hi Holger,
Greetings from Syncfusion support.
We would like to inform you that, if we want to render the every cell based on the day in the different color means, we need to access the td element for the particular table cell and add the corresponding back ground color to them. We could not access the DOM element in the server side and there is no possible to achieve the requested requirement in the server side.
Regards,
Sureshkumar P.
