I am debugging Silverlight 2 on Firefox. I get an unhandled error in firebug:
Unhandled Error in Silverlight 2 Application Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED)) at MS.Internal.XcpImports.CheckHResult(UInt32 hr) at MS.Internal.XcpImports.GetValue(INativeCoreTypeWrapper obj, DependencyProperty property) at System.Windows.DependencyObject.SetValueInternal(DependencyProperty dp, Object value, Boolean allowReadOnlySet, Boolean isSetByStyle, Boolean isSetByBuiltInStyle, PropertyInvalidationReason reason) at System.Windows.DependencyObject.SetValueInternal(DependencyProperty dp, Object value) at System.Windows.DependencyObject.SetValue(DependencyProperty dp, Object value) at System.Windows.Data.BindingOperations.SetBinding(DependencyObject target, DependencyProperty dp, BindingBase binding) at System.Windows.FrameworkElement.SetBinding(DependencyProperty dp, Binding binding) at FileAudit.Page..ctor() at FileAudit.App.Application_Startup(Object sender, StartupEventArgs e) at System.Windows.CoreInvokeHandler.InvokeEventHandler(Int32 typeIndex, Delegate handlerDelegate, Object sender, Object args) at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, String eventName)
points to Silverlight.js line 26 which is
control = new ActiveXObject('AgControl.AgControl');

Why is it not getting handled in JS and being displayed in errorLocation?
Also sorry my formatting sucks.
Came up with a solution
Went to the App.xaml.cs file and reworked the Unhandled_Exception Function
With that and a bit of call this JS it was easy
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 });
}
then for the JS
function foo2(theAlert) {
$("#errorLocation").html(theAlert);
}
I also figured out what the original error was
ClientIdTextBlock.SetBinding(TextBox.TextProperty, ClientIdBinding);
A textBox binding for a TextBlock...stupid mistake.
