Datagrid.....Urgent.....Pls help~!!!!!!!

Hi all,

I'm doing an .Net web application and is currently dealing with datagrids.

I wish to create 3 datagrids and combine them together. What i mean is that i wish to have a small datagrid within a medium datagrid within a over large datagrid.

So far I'm able to create all three datagrids and have the medium datagrid within the large datagrid. But i'm still unable to put the small datagrid into the medium datagrid.

I wonder if anybody could help.......

Thankx!!!
