Hello, Nechama,
According to the provided information, I suppose that you want to customize the default DayViewHeader element and add some check boxes underneath the date. The easiest way to achieve this is to use SchedulerElementProvider class which allows to replace the default RadScheduler element with custom ones. Please, refer to the following article for further information: https://docs.telerik.com/devtools/winforms/controls/scheduler/fundamentals/scheduler-element-provider-
You need to create SchedulerElementProvider descendant class and override the CreateElement method, as shown in the following code snippet:
After that you need to create your custom element which should be inherit of the SchedulerHeaderCellElement class and override some of its the default properties and methods. Indeed, you can create a stack layout element which will contains the date and the check boxes in itself. Please refer to the following code snippet which demonstrates how to achieve the illustrated result:
I hope this information helps. If you need any further assistance please don't hesitate to contact me.
