Sort on bound DataGrid

[Ya Ya]

I have create a page with SQLDateAdapter, SQLConnetion, DataSet and
Datagrid.
I have bound the Datagrid at design time.
I could not find a way to perform sort operation on the datagrid this way.
I could only sort when I am not bounding the datagrid at design time
Anyone has a code example for that (datagrid is bound in the designer) ?

Thanks for your time
