On taskbar edit action, the taskbarEditing event will be triggered. You can prevent the taskbar from editing using the taskbarEditing event. This can be done by setting cancel property of taskbarEditing event argument to true. And we can hide the taskbar editing indicators like taskbar resizer, progress resizer and connector points by using queryTaskbarInfo event. The following code example shows how to achieve this.
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { GanttComponent, Inject, Edit } from '@syncfusion/ej2-react-gantt';
import { data} from './datasource';
function App(){
const taskFields = {
id: 'TaskID',
name: 'TaskName',
startDate: 'StartDate',
duration: 'Duration',
progress: 'Progress',
child: 'subtasks'
};
const editOptions = {
allowTaskbarEditing: true
};
function taskbarEditing(args){
if (args.data.TaskID == 4) // We can't edit Task Id 4
args.cancel = true;
};
function queryTaskbarInfo(args) {
if (args.data.TaskID == 6) {
args.taskbarElement.className += ' e-preventEdit' // Taskbar editing indicators are disabled
}
};
return <GanttComponent dataSource={data} taskFields={taskFields}
editSettings={editOptions} taskbarEditing={taskbarEditing} height = '450px' queryTaskbarInfo={queryTaskbarInfo}>
<Inject services={[Edit]} />
</GanttComponent>
};
ReactDOM.render(<App />, document.getElementById('root'));import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { GanttComponent, Inject, Edit, EditSettingsModel } from '@syncfusion/ej2-react-gantt';
import { data} from './datasource';
function App(){
const taskFields: any = {
id: 'TaskID',
name: 'TaskName',
startDate: 'StartDate',
duration: 'Duration',
progress: 'Progress',
child: 'subtasks'
};
const editOptions: EditSettingsModel = {
allowTaskbarEditing: true
};
function taskbarEditing(args: any){
if (args.data.TaskID == 4) // We can't edit Task Id 4
args.cancel = true;
};
function queryTaskbarInfo(args: any) {
if (args.data.TaskID == 6) {
args.taskbarElement.className += ' e-preventEdit' // Taskbar editing indicators are disabled
}
};
return <GanttComponent dataSource={data} taskFields={taskFields}
editSettings={editOptions} taskbarEditing={taskbarEditing} height = '450px' queryTaskbarInfo={queryTaskbarInfo}>
<Inject services={[Edit]} />
</GanttComponent>
};
