  Hello Gururaj,
  
  FindControl searches only in the current Naming container, as documented in the MSDN. So, since both the RadPanelbar class and the RadPanelItem are naming containers, you need to search inside the RadPanelItem and not in the RadPanelbar itself.

  Hello Gururaj,
  
  FindControl is a generic ASP.NET framework method, documented in MSDN.

  Would it really have been that hard for you to post an example?

  Hello Jim,
  
  Checkout the following example which shows how to access the controls placed in ItemTemplate of PanelBarItem.
  
  ASPX:
  

  <telerik:RadPanelBar ID="RadPanelBar1" runat="server">

  <Items>

  <telerik:RadPanelItem runat="server" Text="Catelog" Value="Catelog">

  <ItemTemplate>

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

  </ItemTemplate>

  <Items>

  <telerik:RadPanelItem runat="server" Text="Child1">

  <ItemTemplate>

  <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

  </ItemTemplate>

  </telerik:RadPanelItem>

  <telerik:RadPanelItem runat="server" Text="Child2">

  </telerik:RadPanelItem>

  </Items>

  </telerik:RadPanelItem>

  </Items>

  </telerik:RadPanelBar>

  
  CS:
  

  protected void Button1_Click(object sender, EventArgs e)

  {

  // Get reference to the panelbaritem which contains control

  RadPanelItem panelItem1 = (RadPanelItem)RadPanelBar1.FindItemByText("Catelog");

  Label Lbl = (Label)panelItem1.FindControl("Label1"); // Use FindControl method to get the control

  Lbl.Text = "Text Changed"; // Set property of control from code

  // Access the panelbaritem which contains control

  RadPanelItem panelItem2 = (RadPanelItem)RadPanelBar1.FindItemByText("Child1");

  TextBox txtBox = (TextBox)panelItem2.FindControl("TextBox1");

  txtBox.Text = "Text Changed";

  }

  Hi Jim, I am enclosing a very interesting code for you to solve this problesm for ever.
  
  
  First it is a class I have done:
  
  

   

   

   

   

  namespace GenLib.Comun 

  {

      public class CtrlFinderPrv 

      {

          public Control FindUniqueControl(Control control, string  id) 

          {

              Control  foundControl = FindUniqueControlRecursive(control, id); 

              return  foundControl; 

         }

          protected Control FindUniqueControlRecursive(Control control, string id) 

          {

              Control foundControl = null; 

              if (control.ID == id) 

              {

                  foundControl = control;

              }

              else 

              {

                  foreach (Control childControl in control.Controls) 

                  {

                      foundControl = FindUniqueControl(childControl, id);

                      if (foundControl != null) 

                      {

                          break; 

                      }

                  }                

              }

              return foundControl; 

          }

      }

  }

  Then to use it, you just create an instance of it an use like this piece of code
  
  

  // GenlibPrv is a service class I have that creates an instance of CtrlFinderPrv class. 

    

     

  RadEditor aEd = (RadEditor) GenlibPrv.GetCtrlFinderPrv().FindUniqueControl(RadPanelBar1,"PresentadionEd"); 

   if(aEd != null )  

  {

     aEd.ImageManager.UploadPaths = imagepath;

     aEd.ImageManager.ViewPaths = imagepath;

     aEd.ImageManager.DeletePaths = imagepath;

     ...

    

    

    

  I hope this solve all your finding controls problems.
