Hi Scott,
I solved that problem. It was basically java Script problem that has been
solved. However two more requirements:
1) I have to expand the tree by clicking the nodes.
2) When the web application will be first loaded, then the tree will be
expanded with only first level. That means:
If A
--->B
----->D
---->C
---->E
is a tree then my requirement is(When application is first loaded):
A
----->B
------>C
I'm sure it can be done. Can u help me with some direction and sample code?
Thanks
