HI  ,     

See image：

One: For records marked in red, can I select these records and then delete them in batches?

Two: For the pink sections, can I select two groups and delete only all data from the 31st?

Hi aquan,

Greetings from Syncfusion Support,

We have reviewed and validated your query.

Query 1: For records marked in red, can I select these records and then delete them in batches?

Yes, you can select multiple events by holding Ctrl and clicking on each event with the mouse. After selecting, press the Delete key to remove all selected appointments at once.

Query 2: Can I select two groups and delete only all data from the 31st?

You can achieve this by using the deleteEvent method. This method accepts string | number | Record | Record[] as input. If you pass the ID(s) or record(s) of the appointments for the 31st, they will be deleted.
