Hi Team,

Thank you for your response. I just create a empty web form and make it simple to demonstrate the problem.

The code is like the following,

in aspx:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="ListBoxIssue.aspx.cs" Inherits="test_ListBoxIssue" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<!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">

<asp:ScriptManager ID="scriptManager1" runat="server"></asp:ScriptManager>

<div>

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">

<div>

<telerik:RadListBox ID="lbSelected" runat="server" Width="300" Height="500"

EnableDragAndDrop="true" AllowReorder="true" ButtonSettings-ShowReorder="false">

<ItemTemplate>

<span>

<asp:Label ID="lblText" runat="server" Text="Hello"></asp:Label>

<asp:DropDownList ID="ddlDefaultOptions" runat="server">

<asp:ListItem Text="1" Value="1"></asp:ListItem>

<asp:ListItem Text="2" Value="2"></asp:ListItem>

<asp:ListItem Text="3" Value="3"></asp:ListItem>

<asp:ListItem Text="4" Value="4"></asp:ListItem>

<asp:ListItem Text="5" Value="5"></asp:ListItem>

</asp:DropDownList>

</span>

</ItemTemplate>

</telerik:RadListBox>

</div>

</telerik:RadAjaxPanel>

</div>

</form>

</body>

</html>

in code-behind:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using Telerik.Web.UI;

public partial class test_ListBoxIssue : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

lbSelected.Items.Add(new RadListBoxItem());

}

Accepted
