  • Data Binding Enhancements. The nodes.customDataExpr and edges.customDataExpr options allow you to link extra fields (from a data source) to Diagram elements (discussion page).
  • Toolbox Configuration Options. To specify toolbox width toolbox.width, set the number of shapes displayed within a toolbox row toolbox.shapeIconsPerRow, and hide the Toolbox search box toolbox.showSearch. Use new toolboxWidthToHeightRatio property to modify the aspect ratio of toolbox shape items.
  • Toolbox Shape Templates. Introduced a new API for shape templates within the toolbox. Use the customShapeToolboxTemplate option to create a common template for all shapes and the toolboxTemplate option to set a template for an individual shape.

  

• Gantt

  • Editing API Enhancements. The Gantt component invokes these client-side events after a task, a resource or a dependency is modified:

With the new contextMenu.items option, you can customize Gant context menu items (add, remove and reorder items, customize default item behavior, etc.) (discussion page).

• Style Sheets

  • Migration to Sass. Integrate DevExtreme SCSS styles into your application build process. This change also allows you to customize CSS styles and minimize resulting CSS bundles (discussion page).
