Hi Mark,
Thanks for contacting Syncfusion support.
Currently we don’t have support in Grid to perform Delete action when the SelectionMode in Grid is set as Cell. But we have considered this requirement as a feature improvement and logged a feature improvement task “Provide support to perform Delete action in Grid when SelectionMode is Cell” for this requirement. We have planned to implement this and include this feature improvement in our upcoming bi-weekly release which is expected to be rolled out on or before end of April, 2020.
You can now track the current status of your request, review the proposed resolution timeline, and contact us for any further inquiries through this link.
Please get back to us if you need further assistance.
Regards,
Renjith Singh Rajendran.
