Nested DataGrids in WebApplication.

Question

Hello Friends..

I have a prob..
I want a code to show data in Nested Datagrids in VB.net.
I have 3 Tables which are linked to each other using some common fields in it.

I want to show datagrid as...

field 1 [from table one] [its value] 
    field 1.1 [from table two] [its value] 
    field 1.2 [from table two] [its value]
         field 1.2.1 [from table three] [its value]

Like that..and all the fields are nested based on their values in DB that are linked with wach other.

If you could help me..i'll be thankful to your clement effort.
Thanks
