Preserving connector segment changes

This feature ensures that any manual adjustments to connector segments are preserved when the source or target nodes are moved. Additionally, these changes are now fully integrated with the undo/redo stack, allowing users to seamlessly revert or reapply connector segment modifications. This improves precision while editing complex workflows or custom layouts.

Render HTML/SVG template nodes in symbol palette

Users can define and render custom nodes using an HTML or SVG template directly within the symbol palette. It enables rich visual representations, including styled shapes, icons, or interactive elements.

Gantt Chart

Optimized task loading and scrolling performance

Task loading with predecessor validation has been optimized, resulting in up to 3X faster load times. Scrolling performance has also been improved, providing a smoother and more responsive experience when working with large datasets.

DataGrid

Built-in row and column spanning

The DataGrid now supports the automatic merging of adjacent cells with identical values, both vertically and horizontally. When the same value appears in consecutive rows or columns, those cells are combined to create a more streamlined and readable layout. This enhancement improves data clarity and presentation.

Pivot Table

Hierarchical field list in server-side engine

The field list’s TreeView can now be rendered with a hierarchical (folder-like) structure when using the server-side engine. This enhancement aligns the behavior of the server-side Pivot Table with the client-side implementation, offering a more consistent and intuitive user experience across platforms. Explore this feature in this demo.

Query Builder

Performance improvements

The Query Builder component has received performance enhancements across multiple rendering and interaction scenarios. These optimizations reduce loading times for large datasets and complex configurations, benefiting developers building applications with extensive filtering requirements. For example, rendering 1,000 lock groups or rules is now 24.94x faster, enabling smoother query construction in data-intensive applications.

Scenario Performance improvement
Rendering 10 instances 1.82x faster
Rendering 100 instances 3.82x faster
Rendering with 100 rules 3.31x faster
Rendering with 1,000 rules 2.57x faster
Rendering with 100 lock groups or rules 2.01x faster
Rendering with 500 lock groups or rules 1.77x faster
Rendering with 1,000 lock groups or rules 24.94x faster
Rendering with 100 clone groups or rules 1.54x faster
Rendering with 500 clone groups or rules 1.54x faster
Rendering with 1,000 clone groups or rules 2.29x faster
Enabling drag & drop 1.25x faster
100 rules with separate connectors 2.25x faster
1,000 rules with separate connectors 1.33x faster
