    Thanks Satyam!
        it worked! ..but i ran into another problem :(  which is related to the Distortion of treeview (can find the screeshot(Distortion.JPG) as attachment)..

    1.The div in which i am displaying tree is getting displayed with borders.

    2.For the datatable i am using "rowClickEvent" to highlight the row where the user knows on which row he is currently in..in this case the tree nodes appears blank(seems white color is overwriting the nodes) we can see this for "S.No" 1  from the Distortion.JPG attachment..

    what are the possibilities for this sort of distortions.

    You are giving the tree the id of an element that doesn't yet exist so
    it can contain it, nor can the tree parse what you haven't placed in
    that element yet. First you have to fill the cell, then you may refer
    to its contents.
