  Hey,
  
  I'm trying to use RADHtmlPlaceHolder to show a PDF file by setting the SourceUrl to this URL:
  http://173.45.117.66/ArcGIS/rest/services/Duke_GDB/FeatureServer/3/109/attachments/38
  
  Instead of showing the PDF file inside the RADHtmlPlaceHolder I see the Open/Save file Dialog (in Internet Explorer).
  
  Is there anyway to show this PDF inside the RADHtmlPlaceHolder?
  
  Thanks,
  Mano

  Hello Mano Sadeh,
  
  You can set the PDF in an iframe inside an html page and use the HTMLPlaceHolder to display this page. I prepared a sample project illustrating this approach. Please take a look at it and let me know if it works for you.

  Hi Sandip,
  
  I am not sure what might be causing this issue. How do you define the pdf source in the IFrame element - is it with an absolute or relative URI? If the URI isn't absolute, can you try defining the absolute path to the PDF document and see if the issue is resolved? Also, you might be experiencing cross-domain issues so you should check your cross-domain policy as well.
  
  Unfortunately, since I can't reproduce the issue on our side I am merely shooting in the dark. But if you manage to create a sample reproducing your scenario and the issue, we will be able to further investigate it.
  
  Kind regards,

  Tina:
  
  Sorry to hijack another thread, but I think that this is related.
  
  I have a site inside a RadHtmlPlaceholder that needs to be able to pass data to the outer Silverlight application. I have tested this using sample code from Telerik and it works really slickly using the [ScriptableType] options. However, the HTML page that I am hosting is on a different machine, and when I try to use that it throws:
  
  --
  [09:17:38.219] Permission denied to access property 'GetSilverlightApplication' @ http://localhost:2118/Event/AddOrder/Promotional/29614:239
  
  I expect that this is a cross-site/domain issue - but in this case it is between two different application running on different ports on localhost. Does that count as cross-domain, and if so is there a good workaround to allow privilege, or to pass a reference to the Silverlight object into the RadHtmlPlaceholder?
  
  Thank you!
  Andy

  Hello Andy,
  
  In this case Silverlight can consider the two applications as hosted on different domains only because they are hosted on a different ports. So setting up a cross-domain policy can help you overcome this issue.
  
  In a cross-domain call the Silverlight first looks for the clientaccesspolicy.xml file. If this file doesn't exists it will look for the crossdomain.xml file. More information about how to set up these files you can find here.
  
  Let us know if we can further assist you.
  
  All the best,

  This could be caused by your HTTPHandler adding a header
  

   

  context.Response.AddHeader("Content-Disposition", "attachment;filename=" +

  fileName);

  
  which will cause the browser to save the file instead of display it.
