Hi All,

I tried to use RadHtmlPlaceholder and catched this Error. However, I can use this control rightly before. I don't get the reason.

I just tried to create a simple Project only use RadHtmlPlaceholder, and still failed.
Here is some code snippet,.
<Grid x:Name="LayoutRoot">
        <telerik:RadHtmlPlaceholder Name="htmlPlaceholder"></telerik:RadHtmlPlaceholder>
    </Grid>

public MainPage()
        {
            InitializeComponent();
            this.htmlPlaceholder.SourceUrl = new Uri("http://www.google.com");
        }

<body>
    <form id="form1" runat="server" style="height:100%">
    <div id="silverlightControlHost">
        <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">
          <param name="source" value="ClientBin/RadControlsSilverlightApp2.xap"/>
          <param name="onError" value="onSilverlightError" />
          <param name="background" value="white" />
          <param name="minRuntimeVersion" value="4.0.50826.0" />
          <param name="autoUpgrade" value="true" />
          <param name="windowless" value="true" />
          <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=4.0.50826.0" style="text-decoration:none">
              <img src="http://go.microsoft.com/fwlink/?LinkId=161376" alt="Get Microsoft Silverlight" style="border-style:none"/>
          </a>
        </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div>
    </form>
</body>

Hello Yue,

Thank you for contacting us. In its core, RadHtmlPlaceholder is an IFrame that is rendered on top of the Silverlight plugin. Recently, Google disallowed displaying some of their pages inside an IFrame and this issue is out of our hands. If you try and display http://www.telerik.com or http://www.yahoo.com you will see that it works without any troubles.
