Load page into RadSplitter Pane

[Jonathan]

Hi,

I've tried everything I can think of to get this to work and can see no examples, so hopefully somebody can help here.  My RadTreeView is situtated within a RadPane which is within a RadSplitter.  I just want to load the page into another RadPane when an item is clicked in the RadTreeView.  How can I achieve this if I want to load the page into ContentPane when a node in PageListTreeView is clicked in the example below?

<telerik:RadPane ID="OuterContentPane" runat="server" Scrolling="None" BorderSize="0">
    <telerik:RadSplitter ID="EntityPaneSplitter" runat="server" Orientation="Vertical" BorderSize="0" VisibleDuringInit="false">
        <telerik:RadPane ID="EntityPane" runat="server" Height="100%" Width="250px" MinWidth="250" Scrolling="None">
            <telerik:RadTreeView ID="PageListTreeView" runat="server" ExpandAnimation-Type="Linear" ExpandAnimation-Duration="250" EnableEmbeddedSkins="false" Skin="KSSG" />
        </telerik:RadPane>
    <telerik:RadSplitBar ID="MainPaneSplitBar" runat="server" CollapseMode="Both" />
        <telerik:RadPane ID="MainPane" runat="server" Scrolling="None">
            <telerik:RadSplitter ID="MainPaneSplitter" runat="server" Orientation="Horizontal" BorderWidth="0" VisibleDuringInit="false">
                <telerik:RadPane ID="ContentPane" runat="server" ContentUrl="Administrator.aspx" BorderWidth="0"></telerik:RadPane>
            </telerik:RadSplitter>
        </telerik:RadPane>
    </telerik:RadSplitter>
</telerik:RadPane>

Thanks in advance.
