Any updates on this?

WiniUI doesn't have an in-box DataGrid, so you are using a control that is maintained elsewhere. Probably the Windows Community Toolkit.

We are using the DataGrid control from the Windows Community Toolkit.

@DhivyaBharathi-SF3890 Yes, and that is maintained in the Windows Community Toolkit repo. Issues with that DataGrid should be raised there:
