Chart runtime exceptions in your samples

[Robbe Morris]

When you run your samples for the Chart control to look at the 3d pie chart, these errors are thrown.  Your code is a pretty simple bind to IEnumerable.  What should I do to avoid this when plugging your charts into my app?

 

System.Windows.Data Error: 23 : Cannot convert '{DisconnectedItem}' from type 'NamedObject' to type 'System.Collections.IEnumerable' for 'en-US' culture with default conversions; consider using Converter property of Binding. NotSupportedException:'System.NotSupportedException: ReferenceConverter cannot convert from MS.Internal.NamedObject.

Hi Robbe,

Thank you for your exception detail!

Unfortunately we might need some more information in order to better understand what's going on. Will it be possible for you to prepare a small sample application that reproduces this exception?

Open "C:\Program Files (x86)\Telerik\RadControls for WPF Q1 2012\Demos\ExamplesCS_WPF.sln" in Visual Studio and run it.  Then, open up the chart samples and run the 3d pie chart.

Hi Robbe,

We reproduced the output errors and I am happy to announce that our developers were able to track down and fix them. You can get the fix with the next LIB that will be available on Monday. Please update your binaries when it becomes available and let me know if it solves the problem.

Kind regards,
