  1. I have a menu with a menu item called �Rename� �
    when I click that my folder should be in edit mode. suggest me how to do that.

After selecting a node and when I click delte key I need to call a function �
please give me a example.

  1. You must define a custom
    onclick handler by

           
menu.setOnClickHandler

(user defined function will receive a menuItem id and
tree item id as first and second parameters.)

 and on clicking Rename button call next code for tree

           
tree.editItem(tree_item_id);

 2. There are no such functionality available by default.
But you can extend existing keyboard_navigation functionality.

           dhtmlXTreeObject.prototype._onkey_delete=function(){

                 
//your onDelete code

          }

          tree.assignKeys([[“delete”,key_code_of_delete_key]]);
