Hi Igor,
In SfDataGrid we can add, remove and update more number of records efficiently when performing sorting, grouping and more summaries in place. But in GridTreeControl Filtering and Grouping, summaries are not supported and it has the Soring option only. In this case the performance issue does not occurwhen performing batch updates. However, when performing the add, remove, update operations in GridTreeControl the property changes occurs and updates the UI instantly.
