Thank you for using Syncfusion products.
As you shared, we have already considered this “Support for Scaling or Zooming in SfDataGrid” Xamarin.Forms. We are always trying to make our products better and feature requests like yours are a key part of our product growth efforts.
At the planning stage for every release cycle, we review all open features and identify features for implementation based on specific parameters including product vision, technological feasibility, and customer interest. We will let you know when this feature is implemented.
If you have any more specification/suggestions to the feature request, you can add it as a comment in the portal.
