Hi,

I have Default.aspx page like this ..

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>
 
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

</head>
<body>
    <form id="form1" runat="server">
    <telerik:RadScriptManager runat="server" ID="RadScriptManager1" />
    <telerik:RadSkinManager ID="QsfSkinManager" runat="server" ShowChooser="true" />

            <telerik:AjaxSetting AjaxControlID="RadButton1">

                    <telerik:AjaxUpdatedControl ControlID="RadPanelBar1" LoadingPanelID="RadAjaxLoadingPanel1">
                    </telerik:AjaxUpdatedControl>
                </UpdatedControls>
            </telerik:AjaxSetting>          
        </AjaxSettings>
    </telerik:RadAjaxManager>
    <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server">
    </telerik:RadAjaxLoadingPanel>
    
    <div>
        <telerik:RadPanelBar runat="server" ID="RadPanelBar1" Height="200" ExpandMode="FullExpandedItem">
        </telerik:RadPanelBar>
    </div>
    <telerik:RadButton ID="RadButton1" runat="server"   Text="RadButton">
    </telerik:RadButton>
    
    </form>
</body>
</html>

Default.aspx.vb :

Imports Telerik.Web.UI
 
Partial Class _Default
    Inherits System.Web.UI.Page
 
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not Page.IsPostBack Then
 
        End If
    End Sub
 
    Protected Sub RadButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadButton1.Click
        Dim i As Integer = 0
        If RadPanelBar1.Items.Count = 0 Then
            Do While (i < 5)
                Dim dateItem As New RadPanelItem()
                dateItem.Text = "Test" + i.ToString()
                RadPanelBar1.Items.Add(dateItem)
 
                Dim control As New RadPanelItem()
                Dim Panel1 As New Panel()
                Session("testText") = " Label" + i.ToString()
                Dim myControl As Control = LoadControl("TestUC.ascx")
                Panel1.Controls.Add(myControl)
                control.Controls.Add(Panel1)
                dateItem.Items.Add(control)
 
                i = i + 1
            Loop
        End If
    End Sub
End Class

ASCX :

<%@ Control Language="VB" AutoEventWireup="false" CodeFile="TestUC.ascx.vb" Inherits="TestUC" %>

<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>

ASCX.VB :

Partial Class TestUC

Inherits System.Web.UI.UserControl

Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init

End Sub

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Not Page.IsPostBack Then

Label1.Text = Session("testText")

End If

End Sub

End Class

When I am click on RadButton1 then I am adding 5 times usercontrol dynamically .If RadPanelBar1.Items.Count = 0 ..So I can able to see label value in 5 usercontrols that added in to radpanelbar.

If I click on RadButton1 2nd time then nothing to do becuase 5 time usercontrol added already in to radpanelbar.. that's why I put condition like this

If RadPanelBar1.Items.Count = 0
' Add user control here..
End If

Above condition causes nothing loaded in to UI.
