Drag and Drop the Record from another component to Gantt
17 Feb 20224 minutes to read
In Gantt, it is possible to drag a record from another component and drop it in Gantt chart with updating the Gantt record. Here, dragging an item from TreeView component to Gantt and that item is updated as a resource for the Gantt record, we can achieve this, by using nodeDragStop event of TreeView control.
<ejs-gantt id='Gantt' dataSource="ViewBag.DataSource" height="280px" gridLines="Both" treeColumnIndex="1"
resources="ViewBag.projectResources">
<e-gantt-taskfields id="TaskId" name="TaskName" startDate="StartDate" endDate="EndDate" duration="Duration"
resourceInfo="Resources" progress="Progress" dependency="Predecessor" child="SubTasks">
</e-gantt-taskfields>
<e-gantt-editsettings allowEditing="true"></e-gantt-editsettings>
<e-gantt-resourcefields id="ResourceId" name="ResourceName"></e-gantt-resourcefields>
<e-gantt-labelSettings rightLabel="${if(Resources)}${Resources}${/if}"></e-gantt-labelSettings>
</ejs-gantt>
<ejs-treeview id="treedata" allowDragAndDrop="true" nodeDragStop="nodeDragStop">
<e-treeview-fields dataSource="ViewBag.projectResources" id="ResourceId" text="ResourceName"></e-treeview-fields>
</ejs-treeview>
<script>
function nodeDragStop(args) {
var ganttChart = document.getElementById('Gantt').ej2_instances[0];
var chartEle = ej.base.closest(args.target, '.e-chart-row');
var gridEle = ej.base.closest(args.target, '.e-row');
if (gridEle) {
var index = ganttChart.treeGrid.getRows().indexOf(gridEle);
ganttChart.selectRow(index);
}
if(chartEle){
var index = chartEle.ariaRowIndex;
ganttChart.selectRow(Number(index));
}
var record = args.draggedNodeData;
var selectedData = ganttChart.flatData[ganttChart.selectedRowIndex];
var selectedDataResource = selectedData.taskData.Resources;
var resources = [];
if (selectedDataResource) {
for (var i = 0; i < selectedDataResource.length; i++) {
resources.push(selectedDataResource[i].ResourceId);
}
}
resources.push(parseInt(record.id));
if (chartEle || gridEle) {
var data = {
TaskId: selectedData.taskData.TaskId,
Resources: resources
};
ganttChart.updateRecordByID(data);
var elements = document.querySelectorAll('.e-drag-item');
while (elements.length > 0 && elements[0].parentNode) {
elements[0].parentNode.removeChild(elements[0]);
}
}
}
</script>public IActionResult Index()
{
ViewBag.DataSource = GanttData.ProjectNewData();
ViewBag.projectResources = projectResources();
return View();
}The following screenshot shows dropping record from another component in to Gantt, and Rose Fuller is added as resource for the task Develop floor plan estimation.
