Gridview AJAX hovermenu problem

[Ridge Howison]

Hello, Thank you for reading this post. Here is my situation. I am new to AJAX development. I have a gridview with 4 boundfield columns and 1 buttonfield column. I need to display a popup anytime a user hovers over the buttonfield column and popup a panel which has some database driven text and a button which says "Add this to my plan" and a cancel button on the popup. How do i associate a hovermenu extender to a buttonfield column with targetcontrolid? Does the hovermenu controller need to be associated in the rowcommand of the gridview? How does this need to be done. A code sample or a URL where someone has already done this will help my cause mightily ! Here is the code of what I have <asp:UpdatePanel ID="updPanel" runat="server" UpdateMode="Conditional">                                                       <ContentTemplate>                                                                <ASCPWebC:GridView                                                                         ID="gvProducts" runat="server" DataSourceID="odsProducts"                                                                         OnRowDataBound="RowDataBound" AutoGenerateColumns="false" AllowPaging="true" AllowSorting="true"                                                                         CssClass="datatable" CellPadding="0" CellSpacing="0" BorderWidth="0" GridLines="None" >
