Scrollbar not active

[Kurt Kluth]

I currently load a RadTreeView via an XML file inside a RadPanelBar and as I get the data to load just fine many of the scrollbars to not show.  How can I get these to show if needed. 

Attached is an image of the scrollbars not showing, now if the RadPanelItem that needs to have the scrollbars is active and there is a postback, they will appear.

<telerik:RadPanelBar ID="RadPanelBar1" Runat="server" ExpandMode="FullExpandedItem" Height="700px" Width="280px">
     <Items>
         <%--<!-- DEFAULT TABS FOR EITHER FMS OR POLICYHOLDER -->--%>
         <telerik:RadPanelItem Expanded="true" text="Favorites" Visible="true">
             <ContentTemplate>
                 <telerik:RadTreeView ID="_rtvwFavorites" runat="server" DataSourceID="XmlDataSource4" CheckBoxes="True" CheckChildNodes="True" TriStateCheckBoxes="False"  >
                         <DataBindings>
                             <telerik:RadTreeNodeBinding DataMember="Node" TextField="Text" ExpandedField="Expanded" Checked="True" ValueField="ID"></telerik:RadTreeNodeBinding>
                         </DataBindings>
                 </telerik:RadTreeView>
                 <asp:XmlDataSource ID="XmlDataSource4" runat="server" DataFile="~/Common/FavoritesTree.xml" XPath="/Favorites/Node"></asp:XmlDataSource>
             </ContentTemplate>
         </telerik:RadPanelItem>
         <telerik:RadPanelItem Text="Credit Union" Visible="true">
             <ContentTemplate>
                 <telerik:RadTreeView ID="_rtvwCreditUnion" runat="server" DataSourceID="XmlDataSource3" CheckBoxes="True" CheckChildNodes="True" TriStateCheckBoxes="False"  >
                         <DataBindings>

Hello,

I would suggest setting the vertical scroll bar on your RadTreeView container. This will show a disabled vertical scroll bar when not needed.
//css

<style type="text/css">
       .rpTemplate {
           overflow-y: scroll !important;
       }
   </style>

If this solution does not solve your problem please clarify which RadControls version you are using. Could you please confirm that you are replicating this issue under all major browsers?

Hope that this will be helpful.
