Michael - Thanks for the HelloWorld3 example. I am building DNN 5.2.3 Silverlight 3 module: 1) SqlServer 2005 table stores PDF, Excel, Word and TXT files in an IMAGE field. 2) Grid display list of files stored in SqlServer. Upon selecting a file from the grid row, I would like to display the Excel, Word, etc file in a browser or ASPX page (Silverlight can not display). How does the Silverlight XAP open a window to display the selected file? I did this under DNN 4 using 2 ASPX pages: 1) select.aspx: Button click passes the file ID to displayfile.aspx Dim sz As String = "return window.open('" & Me.ModulePath & "displayfile.aspx')" Me.btnGetDoc.Attributes.Add("onclick", sz) 2) displayfile.aspx: Retrieves the Image field file data and displays the file: Response.ContentType = "application/pdf" '' OR EXCEL, WORD, etc Dim bytes As Byte() = CType(mySqlDataReader, Byte()) Response.BinaryWrite(bytes) Response.End() Thanks for help

I posted a tutorial at: http://www.codeproject.com/KB/silverlight/SilverlightMVVMFileManagr.aspx That contains an example of placing a link in Silverlight to download a file from a asp.net website.

Thanks, I have not reviewed your project but definitely will take a look. I did get the module to work: 1) The Silverlight "MainPage.xaml.cs" opens a new window via: System.Windows.Browser.HtmlPage.Window.Navigate( new Uri( "http://localhost/mySite/DesktopModules/DocViewer/displayfile.aspx" ), "_blank" ); Question The URI is hardcoded. In "MainPage.xaml.cs" module, how can I obtain the Websites root url? This did not work. new Uri( "~/DesktopModules/DocViewer/displayfile.aspx" ) I would like to build the path in code - something like: string myURI = someDNNSilverlightGlobalVariable + "/DesktopModules/DocViewer/displayfile.aspx" 2) I saved fileID between Silverlight module and other DNN modules via a Webservice call that saves the SqlServer record key: Webservice.asmx =============== System.Web.HttpContext context = System.Web.HttpContext.Current; context.Cache["fileID"] = webServiceFileIDParamCalledFromSilverLight; 'string type displayfile.aspx.vb ( code behind file ) ======================================== Dim context As HttpContext = HttpContext.Current Dim docKey As String = context.Cache("fileID").ToString()

You can get the website root with code such as: private string GetWebserviceAddress() { string strXapFile = @"/ClientBin/MVMFileManager.xap"; string strBaseWebAddress = App.Current.Host.Source.AbsoluteUri.Replace(strXapFile, ""); return string.Format(@"{0}/{1}", strBaseWebAddress, @"WebService/WebService.asmx"); }
