Saving Dynamically Created Tabs on PostBack

I know this has been asked before, but I feel like I'm losing my way trying to follow the other examples out there.  Does anyone see a straightforward solution to my particular problem?
Goal:
Two column Master Page
Left column contains a list of [stuff] (I'm trying a Repeater with LinkButtons)

Left side looks like this:
<asp:Repeater
    <ItemTemplate>
                <asp:LinkButton ID="lbShowReport" runat="server" Text='<%# Eval("Title") %>' CommandName="Select">
                </asp:LinkButton>
