Repeater links not working with routing in ASP.Net

hi

refer below link:

http://www.aspforums.net/Threads/360946/How-to-hide-remove-ASPX-extension-in-URL-in-ASPNetaspx/

I used above code for my page that data is in datalist:

Customers.aspx

asp:DataList ID="dlCustomers" runat="server" RepeatDirection="Vertical" CssClass="dLmostanad">
    <ItemTemplate>
        <table class="table">
            <tr>
                <th colspan="2">
                    <b>
                        <%# Eval("Name") %></b>
                </th>
            </tr>
            <tr>
                <td colspan="2">
                    <%# Eval("Id") %><br />
                    <%# Eval("Country")%>
                </td>
            </tr>
        </table>
        <asp:ImageButton ID="ImgContinue" runat="server" CssClass="imgconM" ImageUrl="~/Image/Main/Continue.gif"
            CommandArgument='<%# Eval("ID")%>' OnClick="ContinueMostanad" ForeColor="Transparent"
            AlternateText="View"></asp:ImageButton>
    </ItemTemplate>
</asp:DataList>

CustomerDetails.aspx

<h1>
    Customer Details</h1>
<hr />
<b>Customer Id:</b>
<asp:Label ID="lblCustomerId" runat="server" />

Customers.aspx

protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        DataTable dt = new DataTable();
        dt.Columns.AddRange(new DataColumn[3] { new DataColumn("Id", typeof(int)),
                        new DataColumn("Name", typeof(string)),
                        new DataColumn("Country",typeof(string)) });
        dt.Rows.Add(1, "John Hammond", "United States");
        dt.Rows.Add(2, "Mudassar Khan", "India");
        dt.Rows.Add(3, "Suzanne Mathews", "France");
        dt.Rows.Add(4, "Robert Schidner", "Russia");
        dlCostumers.DataSource = dt;
        dlCustomers.DataBind();
    }
}
 
protected void ContinueMostanad(object sender, ImageClickEventArgs e)
{
    ImageButton ImgEdit = (ImageButton)sender;
    Response.Redirect("Customers/" + ImgEdit.CommandArgument);
}

now I have other page that bind data from database in repeater now I want wrote codes for repeater

in above code write code for Imagebutton that was in datalist now I want write it for <a> tag that is in repeater:

	<ul>
		  <asp:Repeater ID="Repeater1" runat="server">
                                <ItemTemplate>
                                    <li><a href='<%#"customerdetails.aspx?Secondclass="+Eval("Secondclass")+"&ID="+Eval("ID")%>' target="_blank">
                                        <%#Eval("Secondclass")%></a></li>
                                </ItemTemplate>
                            </asp:Repeater>
		
	</ul>
</li>
