kendo treeview get selected node data
// First to which ever element you specified your treeview with its datasource
// Create a new variable of it:
var tv = $('.mytree').data('kendoTreeView');
// You can get the node that you select by calling select() on your treeview
var selected = tv.select();
// Then use your selected as a parameter in the dataItem() function.
var item = tv.dataItem(selected);
// Then you can see what kind of data is inside it by e.g.
console.log(item); // and opening the inspector and expanding your item object
// Or
alert(JSON.stringify(item));
// The object you specified in the data source will be shown with other useful variables.
// To see how to use the data source with json check http://jsfiddle.net/NZq4A/2/
