Creation of Child within child using datatable

imranmomin

HI,
I want to create a datatable which has 3 sub child for each parent,but there is seperarte query for each child row that is to be called when the row is clicked.
E.g :- suppose parent1 is the main row, then i click on parent1 and sql query is fired and generate 2 sub child of it, then i click on any one of the sub child again a seperate query is fired and generate again sub child of that sub child.

Hope you understand my query..

Thanks in Advance
