Associating rows in a repeater with rows in a SQL database
===

I have the following repeater that gets filled by the data from a SQL database with let say four columns. Three of them shown in the repeater (Name, Min, Max) and the fourth one being the primary key in the table. If need be I can add the primary key field as an invisible label in the repeater.  

    <asp:repeater id="rpt" runat="server"> 
        <ItemTemplate>                                                   
            <asp:Label ID="repeaterLbl"  text = <%#Container.DataItem("Name")%>  runat="server"/>
            <asp:Textbox ID="repeaterMinNumber"  text = <%#Container.DataItem("Min")%> runat="server"/> 
            <asp:Textbox ID="repeaterMaxNumber" text = <%#Container.DataItem("Max")%>  runat="server"/>  <br />                            
        </ItemTemplate>
    </asp:repeater> 

My question is if I change the text boxes text field (for Min or Max) and wish to save the data back into the SQL table, how can I associate the correct row in the repeater with the correct primary key (or row in the SQL table)? If providing code in code-behind please do so in Visual Basic.
