ActiveReportsJS: What's New in version 3.2

Frozen Headers

A table and a tablix data regions now expose the Frozen Rows and Frozen Columns properties that indicate how many rows and columns should remain visible when a report reader scrolls a report content that does not fit into a visible area of the Report Viewer component.

This feature only works when the Report Viewer mode is Galley.

The Frozen Headers page on the demo web-site shows this feature in action.

Performance improvements

Large reports now render faster than ever. The Sales Dashboard page on the demo web-site shows the report that visualizes 100000 records in a dashboard-like fashion.
