Cell Customization

The cells of the Scheduler can be easily customized either using the cell template or RenderCell event.

Setting cell dimensions in all views

The height and width of the Scheduler cells can be customized either to increase or reduce its size through the cssClass property, which overrides the default CSS applied on cells.

Check for cell availability

You can check whether the given time range slots are available for event creation or already occupied by other events using the isSlotAvailable method. In the following code example, if a specific time slot already contains an appointment, then no more appointments can be added to that cell.

You can customize cells such as work cells, month cells, all-day cells, header cells, resource header cells using renderCell event by checking the elementType option within the event. You can check elementType with any of the following.

Element type Description
dateHeader triggers on header cell rendering.
monthDay triggers on header cell in month view rendering.
resourceHeader triggers on resource header cell rendering.
alldayCells triggers on all day cell rendering.
emptyCells triggers on empty cell rendering on header bar.
resourceGroupCells triggers on rendering of work cells for parent resource.
workCells triggers on work cell rendering.
monthCells triggers on month cell rendering.
majorSlot triggers on major time slot cell rendering.
minorSlot triggers on minor time slot cell rendering.
weekNumberCell triggers on cell displaying week number.
