    <div id="treeview"></div>
    <script>
        $("#treeview").kendoTreeView({
            checkboxes: true,
            check: function(e){
              var dataItem = this.dataItem(e.node);
              var rootNodes = $("#treeview").getKendoTreeView().dataSource.data();
              traverse(rootNodes, function(node) {
                if (node != dataItem) {
                  node.set("checked", false);
                  //node.select($());
                  //node.select().find("span.k-state-selected")
                }
              });
            },
          	select: function(e) {
              var dataItem = this.dataItem(e.node);
              dataItem.checked = true;
              $(e.node).find('input').prop('checked', 'checked');
              this.trigger('check', e);
            },
          dataSource: [ { id: 3, text: "about.html" },
                       { id: 4, text: "index.html"},
                       { id: 5, text: "logo.png"},                        
                       { id: 7, text: "mockup.jpg" },
                       { id: 8, text: "Research.pdf"},
                       { id: 10, text: "February.pdf" },
                       { id: 11, text: "March.pdf" },
                       { id: 12, text: "April.pdf" }]
        });
      
        function traverse(nodes, callback) {
          for (var i = 0; i < nodes.length; i++) {
            var node = nodes[i];
            var children = node.hasChildren && node.children.data();
            callback(node);
            if (children) {
              traverse(children, callback);
            }
          }
        }
      
      	$("#treeview").on('change', 'input', function() {
          let $li = $(this).closest('li');
          $("#treeview").data('kendoTreeView').select($li);
        });
    </script>
</body>
</html>

I've added the following code:

// To the grid options
select: function(e) {
    var dataItem = this.dataItem(e.node);
    dataItem.checked = true;
    $(e.node).find('input').prop('checked', 'checked');
    this.trigger('check', e);
},

// After grid initialization
$("#treeview").on('change', 'input', function() {
    let $li = $(this).closest('li');
    $("#treeview").data('kendoTreeView').select($li);
});

The first snippet makes sure that selecting an item by clicking it's label, the checkbox will be checked as well. That event also call check event to uncheck other items.

The last one makes sure a checkbox changed will be trigger the select event, doing the same as above.

I hope it helps.
