Hi Cosyspro,
Thank you once again for your valuable feedback and for sharing the detailed use case.
We have logged a feature request to provide support for disabling row selection and unselection in SfDataGrid when the user clicks the right mouse button. With this enhancement, selection behavior can be restricted to left-click interactions only. This will be considered for inclusion in one of our upcoming releases, and we will notify you once the feature is implemented.
You can also track and communicate with us regarding open feature requests at any time through our Feature Report page:
If you have any additional specifications or suggestions for this feature, please feel free to add them as comments on the portal and cast your vote to help prioritize the request.
We appreciate your continued support and patience.
Best Regards,
Muthu Kumar Madasamy.
