ListBox with radio Button Problem

[<richa soc-soft com>]

Hi all,

I have created a treeview in which I have radion buttons in first column
& some text in 2nd column. When I click on any radio button of other row
I could see both the rows having radio buttons .

How can I make them mutually exclusive? If 3rd is clicked 1st shud not
show radio on it.

Please help me soon its urgent.

Below is the code for reference.......
