datagrid to allow drag and drop operation from tree control nodes dynamically

[phani]

Hello friends...

Im breaking my head since two weeks.
Reason is....
I had a datagrid with 5 rows and 5 columns initially. Beside the Datagrid i hav 5 tree controls adjacent to 5 rows respectively. Now my task is, I hav to drag a node from first tree which is adjacent to first grid row and drop those first tree nodes into first row of the datagrid only.
Similarly, the other tree nodes should be accessed onto adjacent datagrid rows respectively.

Also, i wan to add and delete datagrid rows dynamically.


can any one, plz help in this....

Hello friend,


Im sending a sample screen shot of my task in the following link.

plz see it.

http://203.163.252.17/flexmatrixdemo/bin/Login.html

u just enter any desired login username and pwd to proceed into my main screen.

At the main screen.. there will be a main tree adjacently follwed by sub trees.
If i drag any node from first sub tree(P1-->R1), then that particular node should be dropped into first row of my grid only. if i drop into second,third,r other rows of grid , the node should not be allowed to drop into those rows.
similarly, second sub tree nodes are responsible to drop into second grid row only. the other sub tree nodes follows the same.

In my sample, i took a datagrid back side and i placed list boxes on each row column.
but i know it seems blunder what i did.



so, plz assist me as soon as possible.
