Thanks for the reply. I have one more question regarding WebDataTree.

I have two webdatatrees, and  they are populated with the same data initially. I can drag any item from webdatatree1 and drop it to the webdatatree2 , so the levels of any node in webdatatree2 can be changed. There  might be a case where a new level is added to a node. Can someone suggest an efficient way to bind webdatatree so that it reflects all the dynamic changes made.The sql table I am using to generate webdatatree is :

Level_ID  Parent_ID Child_ID

0                  A                  B

1                 B                   C

2                C                    D

1               E                     F

1                G                   H

2                H                   I

3                 I                    J

I used webhierarchicaldatasource with self reference data but I am not getting the desired results. For the data I copied earlier, I want level 0 at root level then level 1 children then level 2 children. The rows with new levels can be added to the tree and also the existing rows can be deleted. Can you please provide a code how to bind it on the server side so that I can get all the levels of a tree. These levels are not static for example: the levels at 5 currently has no children but if I drop a node there then the next time the tree is loaded it should show a child at level 6. Please help I need the code urgently.
