your gridview doesnt have event wired in markup.

try adding in onrowcommand="gridviewproducts_rowcommand" looks this:

<asp:gridview id="gridviewproducts" runat="server" autogeneratecolumns="false"  backcolor="white" bordercolor="#999999" borderstyle="solid" borderwidth="1px"  cellpadding="5" cellspacing="1" datakeynames="pkey"  datasourceid="sqldatasourceproducts" forecolor="black" gridlines="vertical" onrowcommand="gridviewproducts_rowcommand">
