BlogEngine and Silverlight

I've had a few people asking me how did I host Silverlight 3 in blog engine.

Silverlight Usercontrol

It was pretty simple really (when you know how)

Basically Silverlight3 needs an <object> tag.

So I created a user control with the object tag and some script handling for client side errors (actually VS2010 did all the hard lifting).

[code:c#]

<%@ Control Language="C#" ClassName="SilverlightControl" %>

<script runat="server">

</script>


<script type="text/javascript" src="~/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>

  
    <div id="silverlightControlHost">
    <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">
    <param name="source" value="<%Silverlight.xbap%>"/>   // where <%Silverlight.xbap%> is location of silverlight xbap
    <param name="onError" value="onSilverlightError" />
    <param name="background" value="white" />
