Syncfusion React Gantt Chart
The Syncfusion React Gantt Chart (GanttComponent) is a powerful project management component for visualizing, scheduling, and managing tasks over a timeline. It supports auto/manual scheduling, task dependencies, resource planning, interactive editing, Excel/PDF export, and rich customization.
When to Use This Skill
- Implementing a Gantt chart or project timeline in a React app
- Configuring task scheduling (auto, manual, custom modes)
- Setting up task dependencies (FS, SS, FF, SF) and constraints (ASAP, MSO, FNET, etc.)
- Binding local or remote data to the Gantt (local array, DataManager, UrlAdaptor, Ajax)
- Customizing taskbars, labels, milestones, and baselines
- Configuring resources and resource views (including multi-taskbar)
- Enabling editing (dialog, cell, taskbar drag) with validation rules
- Setting up column resize, reorder, freeze, or column menu
- Configuring WBS codes, tree column icons, or serial number columns
- Setting up filtering, sorting, or selection
- Scrolling to specific dates or controlling scroll position programmatically
- Exporting Gantt to Excel or PDF
- Handling Gantt events and enabling advanced features (undo/redo, virtual scroll, critical path, etc.)
- Globalization, localization, and RTL support

Task Scheduling
📄 Read: references/task-scheduling.md
- Auto, Manual, and Custom scheduling modes (
taskMode)
- Unscheduled tasks (duration-only, date-only, none)
- Project start date and end date configuration
- How scheduling mode affects parent task calculation
- Switching between modes dynamically
Task Dependency
📄 Read: references/task-dependency.md

- Mapping
taskFields.dependency in data source (string format: "2FS", "2FS+3d", "2SS+2h")
- Multiple predecessors per task (comma-separated:
"2FS,3FS")
- Offset values with units: day, hour, minute (e.g.,
"2FS+3h", "2FS-1d")
- Drawing dependencies via UI (drag from taskbar connection points)
- Programmatic dependency management (
addPredecessor, removePredecessor, updatePredecessor)
- Connector line customization (
connectorLineWidth, connectorLineBackground)
- Predecessor Offset Synchronization
autoUpdatePredecessorOffset={true} — recalculate offsets on load to account for calendar rules (weekends, holidays)autoUpdatePredecessorOffset={false} — display original offsets even if not matching rendered lines (visual inconsistency possible)
- Offset Updates During Editing
updateOffsetOnTaskbarEdit={true} — auto-recalculate offsets when dragging taskbars (default)updateOffsetOnTaskbarEdit={false} — preserve offsets; manual update required via dependency dialog
- Dependency Validation Modes (in
actionBegin event with requestType === 'validateLinkedTask')
respectLink={true} — revert invalid edits to maintain dependency integrityremoveLink={true} — remove conflicting dependencies to allow editspreserveLinkWithEditing={true} — update offsets to maintain links (default mode)
- Validation Dialog — disable all modes to show user-choice dialog (cancel edit, remove link, adjust offset)
- Parent Dependencies —
allowParentDependency={true} allows cross-parent dependencies; false restricts to siblings only
- Show/Hide Dependencies Dynamically — toggle
.e-gantt-dependency-view-container CSS visibility
- Disable Validation —
enablePredecessorValidation={false} disables auto-date validation based on predecessor links

};
const editSettings: EditSettingsModel = { allowEditing: true, allowAdding: true, allowDeleting: true, allowTaskbarEditing: true };
function App() {
return (
<GanttComponent
dataSource={data}
taskFields={taskFields}
editSettings={editSettings}
toolbar={['Add', 'Edit', 'Delete', 'Cancel', 'Update', 'Search', 'ZoomIn', 'ZoomOut', 'ZoomToFit']}
height="450px"
>
<ColumnsDirective>
<ColumnDirective field="TaskID" width="80" />
<ColumnDirective field="TaskName" headerText="Task Name" width="250" />
<ColumnDirective field="StartDate" />
<ColumnDirective field="Duration" />
<ColumnDirective field="Progress" />
</ColumnsDirective>

export default App;
Common Patterns
Enable Editing with Dialog
<GanttComponent
editSettings={{ allowEditing: true, mode: 'Dialog' }}
>
<Inject services={[Edit]} />
</GanttComponent>
Enable Cell Editing
<GanttComponent
editSettings={{ allowEditing: true, mode: 'Auto' }}
>
<Inject services={[Edit]} />
</GanttComponent>
Programmatically Add a Task
const ganttRef = React.useRef<GanttComponent>(null);
const addTask = () => {
ganttRef.current?.addRecord({ TaskID: 10, TaskName: 'New Task', Duration: 3 }, 'Below', 1);
};
Export to Excel
<GanttComponent toolbar={['ExcelExport']} allowExcelExport={true}>
<Inject services={[ExcelExport, Toolbar]} />
</GanttComponent>
Export to PDF
<GanttComponent toolbar={['PdfExport']} allowPdfExport={true}>
<Inject services={[PdfExport, Toolbar]} />
</GanttComponent>
Column-Level Validation Rules
<ColumnsDirective>
<ColumnDirective field="TaskName" validationRules={{ required: true }} />
<ColumnDirective field="Duration" validationRules={{ min: 1, max: 100 }} />
</ColumnsDirective>
Scroll to Date Programmatically
const ganttRef = React.useRef<GanttComponent>(null);
ganttRef.current?.scrollToDate('04/28/2024');
Column Resize with Min/Max Width
<ColumnDirective field="TaskName" minWidth="100" maxWidth="400" allowResizing={true} />
Reorder Columns Programmatically
const ganttRef = React.useRef<GanttComponent>(null);
(ganttRef.current as any).treeGrid.reorderColumns(['Duration', 'Progress'], 'TaskName');
(ganttRef.current as any).treeGrid.reorderColumnByIndex(2, 0);
Persist Tree Expand/Collapse State
const taskFields = { ..., expandState: 'isExpand' };
<GanttComponent collapseAllParentTasks={true} .../>
