[Solved] System.ArgumentException: Value cannot be negative, infinite, or NaN.

[Tim]

Having recently upgraded to build 812, and SL3, and having taken advantage of the fixes to columnwidthmode=fill and proportional column widths, we are suddenly seeing the following exception, usually only early in the application load / initial page creation.  Note that our grids are bound to ObservableCollections which are filled in with WCF asynchronous calls (using HTTP binding).

Any ideas why?

Error: An unknown error has occurred.
Detail: System.ArgumentException
Value cannot be negative, infinite, or NaN.
Parameter name: System.Windows.CustomDependencyProperty

Hi Tim,

Can you send us small example where we can reproduce and debug this?

All the best,

It does not happen with any predictable pattern, yet, so I have not tried to reduce it to a simpler example.  I was hoping others had seen it and knew what the problem is.  It seems to be innocuous and we'll probably add it to the growing list of exceptions we'll silently swallow.  The only predictable part so far has been there is not yet any data in the tables.  We have not seen it once the ObservableCollection(s) have data.

I am seeing this same exception.  You can reproduce it with the online GridView demos.  Run the Enable/Disable or Gridlines Visibility example (others do it as well, but not all of them).  Un-maximize the browser, then resize it smaller vertically.  As soon as the gridview is resized so that no data rows are visible, and only the column headers are showing, the exception is thrown.

Unfortunately I have not had a chance to try to fix or find a work-around for this.

I'm experiencing the same problem. It happens when we run an animation that causes the grid to be very small for a short period of time. It's been bugging me for quite some time now, so I'm going to start a support ticket for this.

Hi,

I believe that we have fixed this problem and the fix is already available in our Latest Internal Build. It is available for download under you client account. I'm attaching a sample application with the latest binaries for your convenience.
Please give it a try and let us know how it goes.

Hi,

That's fast! :)
I'm going to patch my installation.

Thanks for your help.

Is there a workaround?  Some of us may not be able to update the version being used.

Cheers

Hi Jamie,

Unfortunately we are not aware of workaround for this so far.

Kind regards,

Here is an (admittedly ugly) workaround for app.xaml.cs:

    public partial class App : Application
    {
        public App()
        {
            UnhandledException += Application_UnhandledException;
            InitializeComponent();
        }

        private void Application_UnhandledException(object sender, ApplicationUnhandledExceptionEventArgs e)
        {
            // NOTE: This will allow the application to continue running after an exception has been thrown
            // but not handled.
            if (!e.ExceptionObject.StackTrace.Contains("MouseEventArgs") && !e.ExceptionObject.StackTrace.Contains("UpdateScrollBars()"))
            {
                Deployment.Current.Dispatcher.BeginInvoke(
                    () =>
                    {
                        ReportErrorToDOM(e);
                    });
            }
        }
    }

Note the MouseEventArgs works around a wart in Silverlight.  The UpdateScrollBars is for this particular problem.

Yes it is ugly.  I admit that.

At least the user wont be aware of this issue with that "fix" :) .  Thanks. 

[Jamie]

Thanks for checking.
