Je suis en train de déboguer Silverlight 2 sur Firefox. Je reçois une erreur non gérée dans Firebug:L'exception Silverlight n'est pas traitée avec JS

points ligne Silverlight.js 26 qui est

control = new ActiveXObject('AgControl.AgControl');

mon html est

<head> 
<script src="Scripts/jquery-1.3.2.min.js" type="text/javascript"></script>

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

     var errMsg = "Unhandled j Error in Silverlight 2 Application " + appSource + "\n";

</body>

Pourquoi est-il ne reçoivent pas traité dans JS et affiché dans errorLocation?
Désolé aussi mon formatage est nul.

Cela fonctionne-t-il dans Internet Explorer et/ou lorsque vous exécutez Visual Studio ou Blend? – AnthonyWJones

est venu avec une solution
Je suis allé au fichier App.xaml.cs et retravaillé la fonction Unhandled_Exception

Avec cela et un peu d'appel ce JS il était facile

private void Application_UnhandledException(object sender, ApplicationUnhandledExceptionEventArgs e) 
    { 
     // If the app is running outside of the debugger then report the exception using 
     // the browser's exception mechanism. On IE this will display it a yellow alert 
     // icon in the status bar and Firefox will display a script error. 


     // NOTE: This will allow the application to continue running after an exception has been thrown 
     // but not handled. 
     // For production applications this error handling should be replaced with something that will 
     // report the error to the website and stop the application. 
     e.Handled = true; 

     try 
     { 
      ThrowRightError(e.ExceptionObject); 
      //System.Windows.Browser.HtmlPage.Window.Eval("throw new Error(\"Unhandled Error in Silverlight a 2 Application " + errorMsg + "\");"); 
     } 
     catch 
     { 
     } 

    } 
    private void ReportErrorToDOM(ApplicationUnhandledExceptionEventArgs e) 
    { 
     try 
     { 
      ThrowRightError(e.ExceptionObject); 
      //System.Windows.Browser.HtmlPage.Window.Eval("throw new Error(\"Unhandled Error in Silverlight 2 Application " + errorMsg + "\");"); 
     } 
     catch (Exception) 
     { 
     } 
    } 

    private void ThrowRightError(Exception e) 
    { 
     string errorMsg = ""; 
     var exLayer = -1; 
     //errorMsg += String.Format("<br>Layer {0}<hr>", exLayer); 
     Exception ex2 = e; 
     while (ex2 != null) 
     { 
      errorMsg += "Message : <br />" + ex2.Message + "<br />Data :<br />" + ex2.Data + "<br />StackTrace :<br />" + ex2.StackTrace; 
      exLayer++; 
      errorMsg += String.Format("<br>Layer {0}<hr>", exLayer); 
      ex2 = ex2.InnerException; 
     } 
     errorMsg = errorMsg.Replace('"', '\'').Replace("\r\n", @"<br />"); 

     HtmlPage.Window.CreateInstance("foo2", new[] { errorMsg }); 
    }

puis pour la JS

function foo2(theAlert) { 
    $("#errorLocation").html(theAlert); 
}

Je me suis aussi ce que l'erreur d'origine était

ClientIdTextBlock.SetBinding(TextBox.TextProperty, ClientIdBinding);

Une liaison de zone de texte pour un texte Bloc ... erreur stupide.
