Link on datafield in table cell

[crxcte1]

I'm popluating a table through a query and using the control, <asp:BoundColumn DataField="ID" HeaderText="ID"></asp:BoundColumn>. I'm wanting to make the datafield ID a link to query all cells for that ID and display. Does .NET have a control for re-populating.

Fname1 works fine and the link works fine but having problems updating. How can I pass the ID to the query when using a link?

<Columns>
<asp:EditCommandColumn ButtonType="LinkButton" UpdateText="Save&#160;" CancelText="Cancel" EditText="Edit&amp;nbsp"></asp:EditCommandColumn>
<asp:ButtonColumn Text="Delete" CommandName="Delete"></asp:ButtonColumn>
<asp:BoundColumn DataField="ID" Visible=False HeaderText="ID"></asp:BoundColumn>
<asp:HyperLinkColumn Text="ID" HeaderText="ID" DataTextField="ID" DataNavigateUrlField="ID" DataNavigateUrlFormatString="SingleMember.aspx?ID={0}" Target="_parent"></asp:HyperLinkColumn>
<asp:BoundColumn DataField="Fname1" HeaderText="Fname1"></asp:BoundColumn>

//SCRIPT
void updateDataBase(Object s,DataGridCommandEventArgs e){
HyperLink ID = (HyperLink) e.Item.Cells[3].Controls[0];
TextBox Fname1 = (TextBox) e.Item.Cells[4].Controls[0];

//QUERY
string strSQL="UPDATE members set ";
if (Fname1.Text=="") {strSQL +="Fname1=\"Null\",";} else {strSQL +="Fname1='" + Fname1.Text + "' ";}
strSQL += "WHERE ID='" + ID + "';


Query on error:
UPDATE members set Fname1='Chris' WHERE ID=System.Web.UI.WebControls.HyperLink
