This would be a little bit different when working with checkboxes, you would need to loop through the items and see if they are selected, but you get the idea.

And let me state that it was not FUN and I'm sure that there is a better way then what I did below. I have a special circumstance, where the client wanted a new window to open when they clicked on the submit button. So I decided to loop through the grid get the ones that were checked and store them in Session along with the final count of how many were checked. These would later be re-read in the resulting page. I really REALLY hate what I did here and plan on going back to try and find a better way.. so if anyone has any hints :)

Private Sub btnAddWatch_Click(ByVal sender As System.Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles btnAddWatch.Click
        Dim OrthoG As DataGrid
        Dim DGitem As DataGridItem
        Dim Counter As Integer

        Try
            OrthoG = CType(Page.FindControl("DemoGrid"), DataGrid)
        Catch
            OrthoG = Nothing
        End Try

        If Not OrthoG Is Nothing Then
            Counter = 0
            For Each DGitem In OrthoG.Items
                If DGitem.ItemType = ListItemType.Item Or DGitem.ItemType = ListItemType.AlternatingItem Then
                    Dim ck = CType(DGitem.FindControl("ProductChk"), CheckBox)
                    If Not ck Is Nothing Then
                        If ck.Checked Then
                            Session("Ortho" + Counter.ToString()) = DGitem.Cells(1).Text
                            Counter = Counter + 1
                        End If
                    End If
                End If
            Next
            Session("OrthoCount") = Counter
        End If

        Page.RegisterStartupScript("os", "<script language='javascript'>window.open('addtowatchlist.aspx', '_blank', '');</script>")

End Sub
