27 Apr 20234 minutes to read

You can get the specific row and cell index of the Tree Grid by using rowSelected event of the treegrid. Here, we can get the row and cell index by using aria-rowindex (get row Index from tr element) and aria-colindex (column index from td element) attribute.

var treeGrid = new ej.treegrid.TreeGrid({
  dataSource: window.projectData,
  idMapping: "TaskID",
  parentIdMapping: "parentID",
  treeColumnIndex: 1,
  height: 267,
  rowSelected: rowSelected,
  columns: [
    { field: "TaskID", headerText: "Task ID", textAlign: "Right", width: 70 },
    { field: "TaskName", headerText: "Task Name", width: 150 },
    { field: "StartDate", headerText: "Start Date", textAlign: "Right", width: 90,
      format: { skeleton: "yMd", type: "date" } },
    { field: "EndDate", headerText: "End Date", textAlign: "Right", width: 90,
      format: { skeleton: "yMd", type: "date" } },
    { field: "Duration", headerText: "Duration", textAlign: "Right", width: 80 },
    { field: "Progress", headerText: "Progress", width: 80, textAlign: "Right" },
    { field: "Priority", headerText: "Priority", width: 90 }
  ]
});
treeGrid.appendTo("#TreeGrid");
function rowSelected(args) {
  alert("row index: " + " " + args.row.getAttribute("aria-rowindex"));
  alert("column index: " + " " + args.target.closest("td").getAttribute("aria-colindex"));
}
