                            <asp:AccessDataSource ID="AccessDataSource1" runat="server" DataFile="~/Blue Coral DB.mdb"
                                SelectCommand="SELECT * FROM RoomList"></asp:AccessDataSource>
Dim i As Integer
        For i = 0 To GridView1.Rows.Count - 1
            Dim chk As CheckBox = CType(GridView1.Rows(i).Cells(0).FindControl("CheckBox1"), CheckBox)
            If chk.Checked Then
                '
            End If
        Next

I will suggest you to use RowDataBound even of griedview where you can cath each row of gridview and use FindControl method in this event.
