Creating a Hierarchical data grid

Hi I need to create Heirarchical data grid from a database view. I have a view which contains information like Country State District -------------------------------------------------------------------------------- India Kerala Trivandrum India Kerala Kollam India Kerala Ernakulam India Kerala Alappuzha India Tamilnadu Kanyakumari India Tamilnadu Coimbatore India Tamilnadu Ramanathapuram USA Massachusets Boston USA Massachusets Corncord etc.... I need to present the information as Contry: India State : Kerala District Trivandrum Kollam Ernakulam Alappuzha State : Tamilnadu District Kanyakumari Coimbatore Ramanathapuram Contry: USA State : Massachusets District Boston Corncord I need to provide check box on the left of every entity for making a selection. If I select a state all the district should be selected. How can I implement this in a data grid. Or Is there another way to implement this without a data grid ? Any help highly appreciated Thanks Baiju
