function nodeChecking(sender, args) {

           args.set_cancel(true);

       }

Here's the code for single and double-click on a node:

function clientDoubleClickHandler(sender, args) {

           var currentNode = args.get_node();

           var allNodes = currentNode.get_allNodes();

           if (currentNode.get_checked()) {

               for (var i = 0; i < allNodes.length; i++) {

                   allNodes[i].set_checked(false);

                   currentNode.set_checked(false);

               }

           }

           else {

               for (var i = 0; i < allNodes.length; i++) {

                   allNodes[i].set_checked(true);

                   currentNode.set_checked(true);

               }

           }

       }

       function clientNodeClickingHandler(sender, args) {

           var currentNode = args.get_node();

           if (currentNode.get_allNodes().length == 0) {

               if (currentNode.get_checked()) {

                   currentNode.set_checked(false);

               }

               else {

                   currentNode.set_checked(true);

               }

           }

       }
