C# - Linkbutton Inside Repeater For Paging

I'm doing a webpage with a search that brings a lot of information from MSSQL. What I did is a stored procedure that return only the page to be seen on the website. Right now I'm working on the paging as I need to show something similar than google. If you are at page 1 they show first 10 pages and if you are at page 19 they show since page 9 to 28. I think the best option to show the page numbers is using a linkbutton inside a repeater. The problem that I have now is that I do not know the best way to take the page number at postback.

Doing a quick sample I assigned an ArrayList to repeater.datasource:
<asp:Repeater ID="Repeater2" runat="server">
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CommandArgument="<%# Container.DataItem %>"><%# Container.DataItem %></asp:LinkButton>
</ItemTemplate>
</asp:Repeater>
<asp:LinkButton ID="LinkButton2" runat="server" CommandArgument="4654">Test #1</asp:LinkButton>

At my Default.aspx.cs file I have the next code

protected void Page_Load(object sender, EventArgs e)
{
if (this.IsPostBack)
{
string x = LinkButton2.CommandArgument;
//string y = LinkButton1.CommandArgument;
//I know this line will not work since the Linkbutton1 is inside the Repeater.
}

What Shall I do to make it works? Does anyone has a better solution for this paging?
