We are getting a 'System.Windows.FrameworkContentElement' is not a Visual or Visual3D exception in our application. The application has an XamRibbon, a XamDataChart. The chart is inside of an XamDocPanel.
It is thrown when we drag the panel containing the graph and release the left mouse button.
Is there a fix for this? We are using InfragisticsWPF4.Controls.Charts.XamDataChart version 11.2.20112.2076.
There is four year old bug 6846 mentioned from 2008 for this exception in this forum post: http://es.infragistics.com/community/forums/t/12738.aspx
Here are the Infragistics calls in the exception call stack. There is no inner exception. The full call stack of 75+ calls is also included.

Hello,
I have been looking through your post and I tried to reproduce the described behavior in a sample project. In this application (XamRibbonDataChart.zip) I set the DataChart in a ContentPane. Even after dragging and dropping the ContentPane no exception has been thrown. I have tested this with 11.2.20112.2076. Would you please have a look at the project and let me know if I am missing something in your scenario? It will be great if you could modify it so that it represents your issue and I could investigate it further. Thank you in advance.
I am just checking your progress on the issue.
If you have any questions, please do not hesitate to ask.
This was caused by unnecessary Keyboard events being sent by the control even though there was no focus on the control or keyboard activity sent to it.
The work around was to have the control send its keyboard events to c# handlers which would then mark them as handled so that they would not cascade into more keyboard events.
