It seems that TeeChart.WPF throws an exception when double clicking on a subchart (well, at least in my example). I have sample code I can provide, however I would rather not attach it to this post. Is there somewhere else I can send it?

Any solution or work around would be much appreciated, as this is a critical issue for our application.

Thanks!

Hello Jeremy Johnson,

Thanks for your information. I can reproduce your problem here and I have added it in bug list report with number [TW16016722]. We will try to fix it to upcoming maintenance releases of TeeChartFor.Net.

Thanks,

Thanks, Sandra.

Is there any work around you can suggest? If not, is there any way we can get a hot fix?

This is a critical issue which will prevent the shipping of our application and affect product demos.

Thanks for the attention.
Jeremy

Hello Jeremy Johnson,

I am afraid, that at the moment, I can not offer you any workaround. I recommend you to be aware at this forum, our RSS news feed, twitter and facebook accounts for new release announcements and what's implemented on them.

Thanks,

Since I don't need to handle double click events from my chart, for the time being it looks like I can work around the exception with a global exception handler.

Code: Select all

        public App()
        {
            DispatcherUnhandledException += ApplicationOnDispatcherUnhandledException;   
        }

        private void ApplicationOnDispatcherUnhandledException(object sender, DispatcherUnhandledExceptionEventArgs args)
        {
            if (args.Exception is InvalidOperationException && 
                args.Exception.Source == "PresentationCore" &&
                args.Exception.StackTrace.Contains("Steema.TeeChart.WPF.Tools.InnerChart.FireOnMouseDown")	
                )
            {
                Debug.WriteLine( "**** Handling exception due to known bug in Steema TeeChart ****");
                args.Handled = true;
            }
        }
