Implementation of Tree Strucure in ABAP

Question

Hi,
I have to display a report in the tree structure.
            --->Node....
Root Node------>Node....
--->Node.....
>Node....
The report goes like this...Is there any way to implement the same. I have to display the report in ALV.
and it is interactive.
Thanks in advance,

hi sumanth,
you can use htmln:Tree tag for ur problem
u try this code,
<htmlb:tree id      = "t1"
                    title   = "t1"
                    tooltip = "Tooltip for t1"
                    toggle  = "X" >
                <htmlb:treeNode id    = "n1"
                                text  = "n1"
                                image = "@09@" />
                </htmlb:treeNode>
                <htmlb:treeNode id     = "node3"
                                link   = "http://www.xyz.com"
                            text   = "Node3"
                            isOpen = "true"
                            image  = "@A0@" />
          </htmlb:treeNode>
    </htmlb:tree>
u can similarly add any number of trees and their nodes.
and u can also define events in eventhandler corresponding to each child.
try this code in event handler
DATA: event TYPE REF TO CL_HTMLB_EVENT.
  event = CL_HTMLB_MANAGER=>get_event( runtime->server->request ).
  IF event IS NOT INITIAL AND event->name = 'tree'.
    DATA: tree_event TYPE REF TO CL_HTMLB_EVENT_TREE.
    tree_event ?= event.
  ENDIF.
