The axinom-pager is a webcontrol made by axinom. It's an independent
control providing basic-pager-functionality. You can set the amount of
links to show, limit the PageSize and react on events fired by the
pager (for example LinkClicked).
1. Add a reference to the assembly Axinom.Framework.dll.
2. Create a new TestPage (for example Test.aspx) with the following content
<%@ Register TagPrefix="Axinom" Namespace="Axinom.Framework.UI" Assembly="Axinom.Framework" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<html>
<head>
<title>PagerTest</title>
</head>
<body MS_POSITIONING="GridLayout">
<form id="Form1" method="post" runat="server">
Here are a few runbers:<br>
<br>
<asp:Repeater Runat=server ID="numberRepeater">
<ItemTemplate>
<asp:Label Runat=server ID="numberLabel"/><br>
</ItemTemplate>
</asp:Repeater>
<Axinom:AxPager id="numberPager" runat="server" />
</form>
</body>
</html>
As you can see, there is a repeater and the axinom-Pager on this page.

4. Description As you can see, there is a repeater which is bound to a List of 100 Numbers. The Method Filter() returns the set of numbers needed for the page of numbers to show. The Method InitPager sets the base-properties of the Pager like the amount of links to show and how many items should be shown per page. this Method is only called if there is no postback.
2 events are registered in method InitializeComponent(). The first one is for the repeater occurring for each number in the ArrayList bound to the repeater. The second event is for the Pager. If a link is clicked to show another page with numbers, this event is raised and the repeater is bound to the new filtered datasource.
