how can i get a specific value from a datagrid as a string ?

[Gelorge Polyrakis]

I m a begginer in asp so that may be very easy....

I use an access database and vb.net

The code is :
dim dtraw as System.Data.Oledb.oledbdatareader

OleDbConnection1.Open()
dtrav = OleDbCommand1.ExecuteReader() ' oledbcommand 1 is an sql
query
DataGrid1.DataSource = dtrav

DataGrid1.DataBind()

OleDbConnection1.Close()

That works geat but what i want to do is to take a specified value from a
datagrid (for example the third row of
column productid ) as a sting .


Is that possible?? thanks
