Hi,

I am having a silverlight 3.0 application that I have to add to my dotnetNuke 4.05.05 web site, I created the folders and all that are required, copied the .xap file into the destop_modules folder and when I wanted to add this module to the page I got a long list of errors which said silverlight is unavailable.

Can anyone please let me know if the errors are being caused because of the versions, or should I download something else to have silverlight work?

Thanks

 I couldn't run the application on the server, but can you please answer this question  why wouldn't the Silverlight application come up in my dotnetnuke:

This is how I tried to do it:.. I created a new usercontrol control1.ascx to the folder: ModuleName under the DestopModules folder in DNN, copied the required silverlightapplication .xap file, silverlight.js file to the folder,then added the following javascript in the 

control1.ascx file:

<script type="text/javascript" src="\\Servername\DesktopModules\ModuleName\Silverlight.js"></script>

    <script type="text/javascript">

        function onSilverlightError(sender, args) {

            var appSource = "";

            if (sender != null && sender != 0) {

                appSource = sender.getHost().Source;

            }

            var errorType = args.ErrorType;

            var iErrorCode = args.ErrorCode;

            if (errorType == "ImageError" || errorType == "MediaError") {

                return;

            }

            var errMsg = "Unhandled Error in Silverlight Application " + appSource + "\n";

            errMsg += "Code: " + iErrorCode + "    \n";

            errMsg += "Category: " + errorType + "       \n";

            errMsg += "Message: " + args.ErrorMessage + "     \n";

            if (errorType == "ParserError") {

                errMsg += "File: " + args.xamlFile + "     \n";

                errMsg += "Line: " + args.lineNumber + "     \n";

                errMsg += "Position: " + args.charPosition + "     \n";

            }

            else if (errorType == "RuntimeError") {

                if (args.lineNumber != 0) {

                    errMsg += "Line: " + args.lineNumber + "     \n";

                    errMsg += "Position: " + args.charPosition + "     \n";

                }

                errMsg += "MethodName: " + args.methodName + "     \n";

            }

            throw new Error(errMsg);

        }

    </script>

Silverlight works great with DNN. You will find dozens of examples that all work with DNN4 at:

http://dnnsilverlight.adefwebserver.com/

An example of code to properly display your Silverlight module is:

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="View.ascx.cs" Inherits="HelloWorld3.View" %>
<script type="text/javascript">
    function onSilverlightError(sender, args) {
        var appSource = "";
        if (sender != null && sender != 0) {
            appSource = sender.getHost().Source;
        }

        var errorType = args.ErrorType;
        var iErrorCode = args.ErrorCode;

        if (errorType == "ImageError" || errorType == "MediaError") {
            return;
        }

        var errMsg = "Unhandled Error in Silverlight Application " + appSource + "\n";

        errMsg += "Code: " + iErrorCode + "    \n";
        errMsg += "Category: " + errorType + "       \n";
        errMsg += "Message: " + args.ErrorMessage + "     \n";

        if (errorType == "ParserError") {
            errMsg += "File: " + args.xamlFile + "     \n";
            errMsg += "Line: " + args.lineNumber + "     \n";
            errMsg += "Position: " + args.charPosition + "     \n";
        }
        else if (errorType == "RuntimeError") {
            if (args.lineNumber != 0) {
                errMsg += "Line: " + args.lineNumber + "     \n";
                errMsg += "Position: " + args.charPosition + "     \n";
            }
            errMsg += "MethodName: " + args.methodName + "     \n";
        }

        throw new Error(errMsg);
    }
</script>
