React Gantt - tasks

Configures tasks.

Type:

Default Value: null

DevExtreme Gantt Chart - Tasks

Use the dataSource property to bind the UI component to a data source, which contains tasks. If the field names in your data source differ from default names ('id', 'parentId', 'title', 'start', 'end', 'progress', 'color'), use appropriate properties (keyExpr, parentIdExpr, etc.) to map data fields.
