Tree view like control in data grid/repeater

[sridharvenkataramanan]

Hi,
I am trying to display a kind of tree like structure with in a data grid. Can any one suggest how to proceed or which control would be apt?

top nodes
+Cosmetics
+Beverages

Expanding top node cosmetics
-Cosmetics
+Perfumes
-Soap
the soap contains new, search , delete with different options within that
--Edit show assign check reorder
--Search
--Delete


here when the user clicks the cosmetics, and soap they would given edit, search, delete, with many predefined actions like show, assign, check each represents some browser button or drop down to perform some actions.
