My situation is that I have a RadListView with RadDataPager, to display a bunch of calendars. I set the datasource of the RadListView in the code-behind and everything loads correctly. The problem is that the paging functionality does not work. I've created test page that replicates my issue.

My ASPX page:

                    <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Test.aspx.cs" Inherits="Test" %>         
                     
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">         
            <html xmlns="http://www.w3.org/1999/xhtml">         
            <head runat="server">         
                <title></title>         
            </head>         
            <body>         
                <form id="form1" runat="server">         
                <div>         
                    <telerik:RadScriptManager ID="RadScriptManager1" runat="server">         
                    </telerik:RadScriptManager>         
                    <telerik:RadListView ID="lvItems" runat="server" AllowPaging="true">         
                        <LayoutTemplate>         
                            <telerik:RadDataPager ID="dpTopPager" runat="server" PagedControlID="lvItems" PageSize="7"         
                                Skin="Office2007">         
                                <Fields>         
                                    <telerik:RadDataPagerButtonField FieldType="Numeric" PageButtonCount="10" />         
                                </Fields>         
                            </telerik:RadDataPager>         
                            <asp:PlaceHolder ID="itemPlaceholder" runat="server"></asp:PlaceHolder>         
                        </LayoutTemplate>         
                        <ItemTemplate>         
                            <div>         
                                <%#DataBinder.Eval(Container, "DataItem.Value") %>         
                            </div>         
                        </ItemTemplate>         
                    </telerik:RadListView>         
                </div>         
                </form>         
            </body>         
            </html>         
                     

The code-behind:

                    using System;         
            using System.Collections.Generic;         
            using System.Linq;         
            using System.Web;         
            using System.Web.UI;         
            using System.Web.UI.WebControls;         
                     
            public partial class Test : System.Web.UI.Page         
            {         
                protected void Page_Load(object sender, EventArgs e)         
                {         
                    if (!Page.IsPostBack)         
                    {         
                        Dictionary<int, int> items = new Dictionary<int, int>();         
                     
                        for (int i = 0; i < 23; i++)         
                        {         
                            items.Add(i, i);         
                        }         
                     
                        lvItems.DataSource = items.ToList();         
                        lvItems.DataBind();         
                    }         
                }         
            }         
                     

It's a simple demo, it just renders numbers. Now I notice that because I only bind my results on the first load that the paging doesn't work. I noticed that the normal asp.net DataPager control acts the same way, so is it just not possible to enable paging if I don't rebind the RadListView every time the page is changed or am I doing something wrong.?

Thanks.
