27 Apr 20234 minutes to read

To customize default values of pager dropdown, you need to define pageSizes as array of strings.

ej.treegrid.TreeGrid.Inject(ej.treegrid.Page);

var treeGrid = new ej.treegrid.TreeGrid({
  dataSource: window.projectData,
  idMapping: "TaskID",
  parentIdMapping: "parentID",
  treeColumnIndex: 1,
  height: 260,
  allowPaging: true,
  pageSettings: { pageSizes: ["5", "10", "All"] },
  columns: [
    { field: "TaskID", headerText: "Task ID", textAlign: "Right", width: 70 },
    { field: "TaskName", headerText: "Task Name", width: 100 },
    {  field: "StartDate", headerText: "Start Date", textAlign: "Right", width: 100,
      format: { skeleton: "yMd", type: "date" } },
    { field: "EndDate", headerText: "End Date", textAlign: "Right", width: 100,
      format: { skeleton: "yMd", type: "date" } },
    { field: "Duration", headerText: "Duration", textAlign: "Right", width: 90 },
    { field: "Priority", headerText: "Priority", width: 90 }
  ]
});
treeGrid.appendTo("#TreeGrid");
