Hi Julian Mayer,
As of now, DataGrid does not have support for performing
filtering from server side. We have already considered your request as a
feature. We will implement this feature in any of our upcoming releases. 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 appreciate
your patience and understanding until then. You can follow up with the below
feedback for further details,
