New row position in React Gantt component
2 Feb 202315 minutes to read
In Gantt, a new row can be added in one of the following positions: Top, Bottom, Above, Below and Child. This position can be specified through the newRowPostion property. We can make use of the toolbarClick event to create a context menu that specifies the position in which the new row is to be added when adding a record through toolbar click.
The following code snippets demonstrate how to achieve this.
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { GanttComponent, Inject, Edit, EditSettingsModel, Selection, Toolbar, ToolbarItem } from '@syncfusion/ej2-react-gantt';
import { ContextMenuComponent } from '@syncfusion/ej2-react-navigations';
import { data } from './datasource';
function App (){
const taskFields = {
id: 'TaskID',
name: 'TaskName',
startDate: 'StartDate',
duration: 'Duration',
progress: 'Progress',
child: 'subtasks'
};
const editOptions = {
allowAdding: true
};
let ganttInstance;
const toolbarOptions = ['Add'];
let cMenu
function toolbarClick(args) {
if (args.item.id === 'GanttExport_add') {
cMenu.open(40, 20);
}
}
const menuItems = [
{
text: 'Bottom'
},
{
text: 'Above'
},
{
text: 'Below'
},
{
text: 'Child'
},
{
text: 'Top'
}
];
function select(args) {
if (args.item.text === "Bottom") {
ganttInstance.editSettings.newRowPosition = "Bottom";
ganttInstance.openAddDialog();
} else if (args.item.text === "Above") {
if (ganttInstance.selectedRowIndex == -1) {
alert("Please select any row");
} else {
ganttInstance.editSettings.newRowPosition = "Above";
ganttInstance.openAddDialog();
}
} else if (args.item.text === "Below") {
if (ganttInstance.selectedRowIndex == -1) {
alert("Please select any row");
} else {
ganttInstance.editSettings.newRowPosition = "Child";
ganttInstance.openAddDialog();
}
} else if (args.item.text === "Child") {
if (ganttInstance.selectedRowIndex == -1) {

} else {
ganttInstance.editSettings.newRowPosition = "Child";
ganttInstance.openAddDialog();
}
} else if (args.item.text === "Top") {
ganttInstance.editSettings.newRowPosition = "Top";
ganttInstance.openAddDialog();
}
}
