I have radpanelbar defined in my code in front with an embedded user control.

    
            <telerik:RadPanelBar ID="RadPanelBar1" runat="server">  
        
                <Items runat="server">  
        
                    <telerik:RadPanelItem ID="RadPanelItem1" runat="server">  
        
                        <uc:ComponentDescriptionPurpose ID="ComponentDescriptionPurpose" runat="server" /> 
        
                    </telerik:RadPanelItem> 
        
                </Items> 
        
            </telerik:RadPanelBar>

In the code-behind, I need to access a function within the user control. I tried below to find it, but it doesn't work.
How do I find it within the panelbar so I can access its functions?

    
                    Dim ComponentDescriptionPurpose As Telerik.Web.UI.RadPanelBar = DirectCast(Page.FindControl("ComponentDescriptionPurpose"), Telerik.Web.UI.RadPanelBar)  
        
                    ComponentDescriptionPurpose.LoadByOrm(idKey)

Thanks.

Hello Moon,

Here's a sample code snippet that shows the needed approach.

ASPX:

    
            <%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default2.aspx.vb" Inherits="Default2" %> 
        
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
        
            <%@ Register Src="WebUserControl.ascx" TagName="WebUserControl" TagPrefix="uc1" %> 
        
            <!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"> 
        
                <telerik:RadScriptManager ID="RadScriptManager1" runat="server"> 
        
                </telerik:RadScriptManager> 
        
                <telerik:RadPanelBar ID="RadPanelBar1" runat="server"> 
        
                    <Items runat="server"> 
        
                        <telerik:RadPanelItem ID="RadPanelItem1" runat="server" Text="Root RadPanelItem1" 
        
                            Expanded="true"> 
        
                            <Items> 
        
                                <telerik:RadPanelItem runat="server" Value="templateHolder"> 
        
                                    <ItemTemplate> 
        
                                        <uc1:WebUserControl ID="WebUserControl1" runat="server" /> 
        
                                    </ItemTemplate> 
        
                                </telerik:RadPanelItem> 
        
                            </Items> 
        
                        </telerik:RadPanelItem> 
        
                    </Items> 
        
                </telerik:RadPanelBar> 
        
                </form> 
        
            </body> 
        
            </html>

Code-behind:

    
            Imports Telerik.Web.UI 
        
            Partial Class Default2 
        
                Inherits System.Web.UI.Page 
        
                Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 
        
                    Dim txtb As TextBox = DirectCast(RadPanelBar1.FindItemByValue("templateHolder").FindControl("WebUserControl1").FindControl("TextBox1"), TextBox) 
        
                    txtb.Text = "test" 
        
                End Sub 
        
            End Class

You did finally provide me with the solution via the support tickets... So I thought I should share it with others who want to know:

Codebehind:

    
                        Dim ComponentDescriptionPurpose As ComponentDescriptionPurpose = DirectCast(RadPanelBar1.FindItemByValue("templateComponentDescriptionPurpose").FindControl("ComponentDescriptionPurpose"), ComponentDescriptionPurpose)  
        
                        ComponentDescriptionPurpose.LoadByOrm(ReviewId)

Here is the user control setup, code in front:

    
                    <telerik:RadPanelItem ID="RadPanelItemComponentDescriptionPurpose" runat="server">  
        
                        <Items> 
        
                            <telerik:RadPanelItem runat="server" Value="templateComponentDescriptionPurpose">  
        
                                <ItemTemplate> 
        
                                    <uc:ComponentDescriptionPurpose ID="ComponentDescriptionPurpose" runat="server" /> 
        
                                </ItemTemplate> 
        
                            </telerik:RadPanelItem> 
        
                        </Items> 
        
                    </telerik:RadPanelItem>
