Gantt add and edit dialogs can be opened dynamically by using openAddDialog and openEditDialog methods. The following code example shows how to open add and dialog on separate button click actions.
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { ButtonComponent } from '@syncfusion/ej2-react-buttons';
import { GanttComponent, Inject, Edit, Selection } from '@syncfusion/ej2-react-gantt';
import { data } from './datasource';
class App extends React.Component {
constructor() {
super(...arguments);
this.taskFields = {
id: 'TaskID',
name: 'TaskName',
startDate: 'StartDate',
duration: 'Duration',
progress: 'Progress',
child: 'subtasks'
};
this.editOptions = {
allowEditing: true,
allowAdding: true
};
}
editHandler() {
this.ganttInstance.editModule.dialogModule.openEditDialog();
}
addHandler() {
this.ganttInstance.editModule.dialogModule.openAddDialog();
}
render() {
return (<div>
<ButtonComponent onClick={this.addHandler.bind(this)}>Open Add Dialog</ButtonComponent>
<ButtonComponent onClick={this.editHandler.bind(this)}>Open Edit Dialog</ButtonComponent>
<GanttComponent dataSource={data} ref={gantt => this.ganttInstance = gantt} taskFields={this.taskFields} allowSelection={true} editSettings={this.editOptions} height='450px'>
<Inject services={[Edit, Selection]}/>
</GanttComponent></div>);
}
}
;
ReactDOM.render(<App />, document.getElementById('root'));<!DOCTYPE html>

};
ReactDOM.render(<App />, document.getElementById('root'));NOTE: We should select any one of the row in Gantt to open the edit dialog.
