Hi fpellus,

Please, make sure that your Grid is not with height: auto. When height is auto the grid creates UI row for each Data row. Otherwise, it uses virtualization i.e reuses the UI rows. Also make sure that you do not have a logic in editing/updating events which requires loops through all rows. This thing may slow down the Grid.

Best regards,
