I'm getting an unhandled exception from the xamDataChart, it's pretty random but it seems to happen most often when I switch the data series that the chart is to display. Basically when the operator requests to see a different set of values, I clear the chart series and recreate a new set of series to display. This is the info I am getting from the exception. Looking at the inner exception it looks like the chart is trying to set the height of something to infinity?

To troubleshoot the exception occurring the source code is available at My Keys & Downloads that allows you to debug through the code from the assemblies. Looking at the stack trace you can step through RenderFrame method in the ColumnSeries class.

I have tested the software on 64 bit Windows 7. All I know is that the following messages are occurring sporadically: An unhandled exception occurred: Exception has been thrown by the target of an invocation. An unhandled exception occurred: Item has already been added. Key in dictionary: 'Infragistics.Windows.Automation.Peers.DataPresenter.CellAutomation Peer' Key being added: 'Infragistics.Windows.Automation.Peers.DataPresenter.CellAutomation.Peer' I am aware from the marketing materials that Infragistics is touting their latest versions for the tablet (and Windows 8), so I somewhat hope that the problems might just 'go away' if I upgrade. In the absence of any clear information on the subject, however, I'm hesitant to suggest to my customer the cost of a project to upgrade.

From the call stack provides the last method call and knowing where to look at in the source code. As for the case on the xamDataGrid control can be found within the Infragistics.Windows.DataPresenter project.
Switching series is not really the problem, I do it basically the same way that you show in the sample.
Interesting, similar but not quite the same. We are using the 2012 volume 1 version, and we do support a touch screen in some installations (we have a kiosk type device, but we also support a desktop experience). However the issue I see is happens sporadically with the exception implying that the height of some control is getting set to infinity. My guess is that there is some divide by zero error that is setting the property to NAN. But I have no way of confirming or providing an example.
My environment is .Net 4 32bit
FYI We do make limited use of the data grid, and I have not seen any trouble yet...
Hello,
I am investigating an issue with the exact same error message, which was just brought to my attention a few days ago. In my case, it is not in connection with XamDataChart, but I am using Infragistics NetAdvantage for WPF (10.3). I am using XamDataGrid. The problem just suddenly appeared when my client began testing on a Windows 7 64 bit tablet computer. (For clarification, my application is running as a 32 bit app. I am using .Net 3.5.) Are any of those factors similar to your situation? Having searched the web a bit, I have seen some commentary implying that there are perhaps "known" issues with xamDataGrid on tablets (perhaps only in connection with slightly older versions such as mine), but I haven't been able to find any definitive authoritative info on the subject.
I would be interested to learn on what version and on what environment you are seeing the message you reported.
Cheers,
Stan
Hello David,
For switching to different series and different data values I have attached a sample.
