For Each dgi In DataGrid1.Items

Dim productId As Integer = Convert.ToInt32(DataGrid1.DataKeys(dgi.ItemIndex))

    Hi cmh,

    It looks like you are using the Web Forms DataGrid control, rather than the Windows Forms DataGrid. This is a Windows Forms forum, so you might want to try your question at the Data Presentation Controls forum at asp.net.
