Hello, I have a DataGrid and want to be able to mouseover a (LinkButton, HyperLink, <a></a>) control / tag (which ever is easiest of the 3, or possibly all), and somehow retrieve a value from one of the fields (databound fields) in that row. I then want to take that value and perform some processing with it behind the scenes in C#. How would I do this?

my DataGrid

<asp:DataGrid ID="dgSummary" runat="server" AllowPaging="True" AllowSorting="true"
                                PagerStyle-Mode="NumericPages" PagerStyle-Position="TopAndBottom" PagerStyle-HorizontalAlign="center"
                                PagerStyle-BackColor="#CCCCCC" PagerStyle-NextPageText="Next Page" PagerStyle-PrevPageText="Prev Page"
                                Font-Size="14px" AutoGenerateColumns="False" CellPadding="2" PageSize="10" Width="80%"
                                OnPageIndexChanged="dgSummary_PageIndexChanged" OnSortCommand="dgSummary_SortCommand"
                                OnItemCommand="dgSummary_ItemCommand">
                                <HeaderStyle BackColor="#CCCCCC" HorizontalAlign="Center" Font-Bold="true"></HeaderStyle>
                                <Columns>
                                    <asp:TemplateColumn Visible="false">
                                        <ItemTemplate>
