pageable.pageSize Number

The number of data items which will be displayed in the TreeList.

This setting will not work if the TreeList has an already existing DataSource instance.

Example - setting the page size

<div id="treeList"></div>
<script>
    $("#treeList").kendoTreeList({
        columns: [
          { field: "id" },
          { field: "name" }
        ],
        dataSource: {
            data: [
              { id: 1, parentId: null, name: "item 1" },
              { id: 2, parentId: 1, name: "item 2" },
              { id: 3, parentId: 1, name: "item 3" },
              { id: 4, parentId: 1, name: "item 4" },
            ]
        },
        pageable: {
            pageSize: 2
        }
    });
</script>
