Copy paste records in EJ2 TypeScript Gantt control
2 May 20236 minutes to read
You can copy and paste a record in the Gantt chart by using the addRecord
method and custom context menu
. It is also possible to copy and paste the parent record with multiple hierarchical child records on the required position.
import { Gantt, Edit, Selection, ContextMenu } from '@syncfusion/ej2-gantt';
import { GanttData } from 'datasource.ts';
Gantt.Inject(Edit, Selection, ContextMenu);
var copiedRecord: any;
var enableFlag: any;
let gantt: Gantt = new Gantt({
dataSource: GanttData,
taskFields: {
id: 'TaskID',
name: 'TaskName',
startDate: 'StartDate',
duration: 'Duration',
progress: 'Progress',
dependency:'Predecessor',
child: 'subtasks'
},
editSettings: {
allowAdding: true,
allowEditing: true,
allowDeleting: true,
allowTaskbarEditing: true
},
toolbar: ['Add', 'Edit', 'Update', 'Delete', 'Cancel', 'ExpandAll', 'CollapseAll'],
allowSelection: true,
enableContextMenu: true,
contextMenuItems: [
{ text: 'Copy', target: '.e-content', id: 'copy' },
{ text: 'Paste', target: '.e-content', id: 'paste' },
],
contextMenuClick: function (args) {
if (args.item.id === 'copy') {
copiedRecord = args.rowData;
copiedRecord.taskData.TaskID = gantt.currentViewData.length + 1;
}
if (args.item.id === 'paste') {
gantt.addRecord(copiedRecord.taskData,'Below',args.rowData.index);
if(copiedRecord.hasChildRecords) {
addChildRecords(copiedRecord, args.rowData.index + 1);
}
copiedRecord = undefined;
}
},
contextMenuOpen: function (args) {
if (args.type !== 'Header') {
if (copiedRecord) {
args.hideItems.push('Copy');
} else {
args.hideItems.push('Paste');
}
}
},
});
gantt.appendTo('#Gantt');
function addChildRecords(record: any, index: any) {
for(var i=0; i<record.childRecords.length; i++) {
var childRecord = record.childRecords[i];
childRecord.taskData.TaskID = gantt.currentViewData.length + 1;
gantt.addRecord(childRecord.taskData,'Child',index);
if(childRecord.hasChildRecords) {
addChildRecords(childRecord, index + (i+1));
}
}
}
