Hiding a column in Datagrid

[dterza01]

Hi, I am using the following technique to hide a column in a datagrid. It works great, however, I am not able to get the item value anymore by calling

DataGrid1.Item(DataGrid1.CurrentRowIndex(), 0)

Is there a way to hide a column using this method and still get the value from the datagrid?
I do not want to use a Datagrid Table Style

Dim cn As New SqlConnection("Data Source=MyServer;User Id=MyUser;Password=MyPassword;Initial Catalog=Northwind")
cn.Open()
Dim da As New SqlDataAdapter("Select * From Products", cn)
Dim ds As New DataSet()
da.FillSchema(ds, SchemaType.Source, "Products")
da.Fill(ds, "Products")
' Next line hides column.
ds.Tables("Products").Columns("QuantityPerUnit").ColumnMapping = MappingType.Hidden
DataGrid1.SetDataBinding(ds, "Products")

Thanks in advance
