    I have modified an example I found on the Telerik site to determine content size in order to adjust a pane and splitter to the size of the content. All works in the example when you hard code some content. However if I set the ContentURL of the pane to an external URL, the sizing no longer works. Any ideas?
    <%@ Page Title="Home Page" Language="C#" AutoEventWireup="true"
        CodeBehind="Default.aspx.cs" Inherits="FrameTest._Default" %>
    <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "">
    <head id="Head1" runat="server">
        <title>Untitled Page</title>
        <script type="text/javascript">
            function SplitterLoaded(splitter, arg) {
                var pane = splitter.getPaneById('<%= RadPane2.ClientID %>');
                var height = pane.getContentElement().scrollHeight;
                splitter.set_height(splitter.get_height() - pane.get_height() + height);
        <form id="form1" runat="server">
            <asp:ScriptManager ID="ScriptManager1" runat="server" />
            <telerik:RadSplitter ID="RadSplitter1" runat="server" Width="200px" Height="200px"
                OnClientLoaded="SplitterLoaded" Orientation="Horizontal">
                   <telerik:RadPane ID="RadPane2" runat="server" ContentUrl="" Scrolling="None">

    Hi Greg Barretta,

     This functionality is not implemented by design but you can achieve it by javascript means. You need to define the following functions:

    - One function in the page which will be loaded in the RadPane and returns the height of the page.
    - One function in the main page (which contains the RadSplitter control) which sets the returned by the previous function height to the RadPane object.
    - Call the main page's sizing function on RadPane's content page load.

    Note, that this can work only for pages in the same domain because of the browsers security - you cannot manipulate and calculate the scrolling of  e.g google page with javascript because if cross domain scripting was allowed, this would lead to hacker attacks.

    You can find a sample demo attached.

    Best wishes,

    the Telerik team
