  Hi,
  
  I'm using the panelbar and whant the first panel to expand, on start.
  
  This is my panel code:
  

  <telerik:RadPanelBar ID="RadPanelBar_Portfolio" Width="100%" Height="100%" CssClass="masterPanelBar"

      ExpandMode="FullExpandedItem" runat="server" >

      <Items>

          <telerik:RadPanelItem Value="MainPanel" Selected="true" Expanded="True">

              <HeaderTemplate>

                  <asp:label ID="Label8" Text="Portfolio" Font-Bold="true" runat="server" />   

              </HeaderTemplate>

              <ContentTemplate>

                  <table id="tbl_HeaderPortFolio" runat="server">

                      <tr>

  ....

                      </tr>

                  </table>

              </ContentTemplate>

          </telerik:RadPanelItem>

      </Items>

  </telerik:RadPanelBar>

  
  The panel bar is inside a RadSplitter.
  The radsplitter is inside a dynamically loaded control, that is in a RadAjaxPanel.
  
  As you can see, I set Selected="true" Expanded="True" 
  but that does not show the panel expanded. I always have to click the bar to see its content (the table)
  
  I tried also to set it in code :
  

  With RadPanelBar_Portfolio.FindItemByValue("MainPanel")

      .Expanded = True

      .Selected = True

      .Expanded = True

      .PreventCollapse = True

  End With

  and even in the PreRender (RadPanelBar_Portfolio.Items(0).Expanded = True)
  
  and I tried setting it in JS:
  

  function ExpandItem()

  {

      var panelbar = <%= RadPanelBar_Portfolio.ClientID %>;

      var item = panelbar.FindItemByValue("MainPanel");

      if (item)

      {

          item.Expand();

      }

      else

      {

          //alert("Item with text 'MainPanel' not found.");

      }

  }

   

  ExpandItem;

  
  But, no luck, the panelbar ALWAYS needs to be clicked first...
  
  Please check screenshot for more details.
  
  Could you tell me how I can see the first panel expanded?
  
  Thanks
  
  Erik

  Hi Erik,
  
  Indeed the behavior that you encounter is a bug of the RadPanelBar control when you use both HeaderTemplate and ContentTemplate that we are already aware of. It is already logged in our internal system and though I can not give you any specific timeframe we will do our best so that we can fix it shortly.
