    I got an HTMLPlaceholder displaying fine inside a TabControl on a Page, and wanted to change to displaying the information in a ChildWindow.

    However, when the ChildWindow, is displayed, the HTMLPlaceHolder is not displaying - just the control containing it.

    The XAML is below - any suggestions, please?

    Thanks,

    James

    Hello James,

    Please find attached a sample project that shows how to use RadHtmlPlaceHolder in a ChildWindow.
    Verify that you are using the latest released assemblies from the SP1 release.

    I hope that this will help you.
    If not please send us the full source code in order to reproduce this issue.

    Sincerely yours,

    Hi,

    I checkout your sample. That's not what I want to do.  It can't display html content while I open it as modal popup.
    For example change your App.xaml.cs Line:29 in your sample like that

     

    this.RootVisual = new Page();

     

     

    ChildWindow ch = new ChildWindow();

     

    ch.Show();

    You will see that it doesn't show the contents.

    Thanks.
    Sincerely

    Hello Nesim,

    Please make sure that you are using the latest released assemblies from our last internal build.
    I tried the example with the following code and it works as expected:

     private void Application_Startup(object sender, StartupEventArgs e)
            {
                this.RootVisual = new Page1();
                ChildWindow window = new ChildWindow();
                RadHtmlPlaceholder placeHolder = new RadHtmlPlaceholder();
                placeHolder.SourceUrl = new Uri("http://www.telerik.com",UriKind.RelativeOrAbsolute);
                window.Content = placeHolder;
                window.Show();
            }

    Please let us know if you have any other questions or need some more help or sample code.

    Best wishes,

    I'm using the latest internal build, and can confirm it's working fine for me now - thanks.
