How do I group columns in a DataGrid?

Hi Krishna.
Thanks for the reply. But the thing is I dont have to use DB its not part of project.. I am binding the DATA to Grid as below :

Grid1.DataSource = itemList; (Where Itemlist is a List of String)

Hope you are clear now..

So plz give me some idea on this or if u have any Sample application then do let me know.

Hai rajendra

You would have attached a datatable to the datgrid to fill data..and the datatable is been filled from the database....

instead fill the datable by using a select query in which combine street,city,country as one column and bind  that column to the particular column in the datagrid..

Example
select Street+City+Country as Address,Roll no+Class+Section as Student  from tablename

and bind Address to column in the datagrid  respectively...

Hope i made myself clear

With Regards
P.Krishna Prasad
