Silverlight RadWindow gives Aw, Snap! error in Chrome 24.0.1312.52 m

[Nilesh]

Hi Team,
    
    I am using Telerik control for the past 4 years for silverlight. But today I am facing an issue using RadWindow in chrome lastest version.
I had a popup for which I am using Telerik RadWindow and in the Content I am passing RadHtmlPlaceholder object.
Case 1: If the RadHtmlPlaceholder contains a plain html page then it works fine.

Case 2: If an Silverlight Page is included in RadHtmlPlaceholder it loads properly first time, but when I click for the second or third time then the Chrome browser crashes

I am working with 
Silverlight Version : 5
Telerik                  :  2011.3.1220.1040
Operating System : Windows 7

Sample Link:  https://www.dropbox.com/s/2rvxoryq4b5fbpi/TelerikRadHTMLControlSample.zip

MainPage.XAML.cs

public partial class MainPage : UserControl
    {
        RadHtmlPlaceholder radHtmlPH;
        public MainPage()
        {

            InitializeComponent();
            radHtmlPH = null;
            radHtmlPH = new Telerik.Windows.Controls.RadHtmlPlaceholder();
            radHtmlPH.HorizontalAlignment = System.Windows.HorizontalAlignment.Stretch;
            radHtmlPH.VerticalAlignment = System.Windows.VerticalAlignment.Stretch;

            // this will work fine
            //radHtmlPH.SourceUrl = new Uri("http://www.telerik.com/support.aspx");  

            // This link crashes second time
            radHtmlPH.SourceUrl = new Uri("http://www.wynapse.com/Silverlight/Telerik/PersistenceFrameworkDataToAString.aspx");

        }
        RadWindow radWinNormal;
        private void Button_Click(object sender, RoutedEventArgs e)
        {

            if (radWinNormal != null)
                radWinNormal.Content = null;
            radWinNormal = new RadWindow();
            radWinNormal.Width = 500;
            radWinNormal.Height = 500;
            radWinNormal.Content = radHtmlPH;
            radWinNormal.ShowDialog();
            //PlaceHolder.Children.Add(radHtmlPH);
        }
    }

MainPage.XAML
<Grid x:Name="LayoutRoot" Background="White">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>
        <Button Content="Place Holder" Click="Button_Click"></Button>

Hi Nilesh,

Thank you for sending the sample solution and a detailed explanation of the issue. However, when working with the RadHtmlPlaceholder you need to have in mind that the control displays external pages in an IFrame object that is placed on top of the SIlverlight plug-in in the page hosting the Silverlight application.

This means that the RadHtmlPlaceholder has limited control over the way the web pages are rendered as the IFrame controls that. And in your case, it seems that a script in the http://www.wynapse.com/Silverlight/Telerik/PersistenceFrameworkDataToAString.aspx page is breaking the IFrame control and it can't always display properly the page thus causing the exception.

But as it seems that this issue only arises on a reload of the web page, you can set the RadHtmlPlaceholder.KeepContentInMemory property to True to make the RadHtmlPlaceholder save the page locally. This way you won't have to reload it every time the window is opened.

I hope this suggestion will help you get over the issue.

All the best,

Hi Tina Stancheva,

   Thanks for your solution this works perfectly fine when the Content page is always the same. This was just a sample I provided but in my real project I am using the same instance of  to load different pages. so in that case I can't us KeepContentInMemory
I need to reload the page everytime.

   Do you have any good solution for such cases.

Hi Nilesh,

Unfortunately if the issues in your real solution are also related to the IFrame rendering of a web page, we can't suggest other solutions. If the IFrame object can't properly display/load a page, the RadHtmlPlaceholder won't display it as well.
