What is the limit on the number of levels which can be viewed in hierarchical mode of ultrawebgrid.

I had heard its only 1. But recently i was playing with it and i could see multiple levels being displayed

as follows with some manual data.

Task

     Task1

        Task 2

But when i try to bind it to data from the database, it shows only 1 level. It just puzzles me what could be

wrong.

Thanks!!!
