Hi Kind,
Thanks for contacting Syncfussion support. Currently the CurrentCellEndEdit/BeginEdit events are only available only for the GridTextColumn, PickerColumn, DateTimeColumn, and NumericColumn. It will be made available for the template columns when the EditTemplate support is given for SfDataGrid. A feature request has already been logged for the EditTemplate support and you can expect the feature to be available in any of the upcoming releases.
Valuing your feedback and we have mentioned about the limitation of the CurrentCellEndEdit/BeginEdit events in our documentation also which will be refreshed online on 23rd March 2017.
Please let us know if you may require further assistance.
Regards,
Vimal Prabhu
