Vue Gantt - tasks

Configures tasks.

Type:

Default Value: null

DevExtreme Gantt Chart - Tasks

Use the dataSource option to bind the widget 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'), use appropriate options (keyExpr, parentIdExpr, etc.) to map data fields.
