Hi Irfan,
Thank you for contacting Syncfusion support.
The mentioned script error will be throw when we using command column for Editing as well as Editmode as batch. Command column feature doesn’t support the batch editing or cell editing. Because batch editing behavior is differing from that all other edit modes. So, we suggest you to use either Edit mode like normal, dialog, inlineform and externalform for command column or batch editing with no command column.
Thank you,
Venkatesh Ayothiraman.
