Getting very strange behaviour from xamDataGrid. Scrolling and filtering is incorrectly changing properties in the underlying datasource and consequently corrupting the datasource. Is this a known issue?
Adding a breakpoint when a property changes reveals the following stack trace:

Hello obiwanzamora,
Thank you for posting!
I have been looking into your issue and have created a small sample application in order to test the functionality you have described. In the sample application I have a simple XamDataGrid bound to a collection. The collection implements INotifyPropertyChanged, so the propertied would be updated when they are changed.
Using this sample application I was not able to reproduce the issue you have reported when scrolling or filtering is performed. I am attaching the sample for your reference.
Would you please modify the sample application with the functionality you are using so it reproduces the issue? This way I would be able to further investigate this matter for you.
Looking forward to hearing from you.
I have tweaked the example to replicate the issue. You will see that once the grid is populated, scrolling down will cause the break point to be hit. Thanks.
Thanks for the response. I have tried what you suggested and placing the XamDataGrid inside a ScrollViewer component along with setting HeightInInfiniteContainers="Infinity" does appear to solve the scrolling issue. However, the issue is still present when filtering using the built-in filter controls. Furthermore, without the virtualization the grid is very slow and unresponsive.
Is there a way that the virtualization functionality can be maintained without triggering the issue we are having?
Is there any update on this?
Is this still being investigated? Please can somebody respond with an update.
At present this is causing regular data corruptions of the underlying data source.
Hi,
We are too facing the similar issue's.
Columns value is getting changed while scrolling the xamdata grid
Try to resolve it by turning of the virtualization, but it slowed down the sorting(Filter) operation
Please let me know is there any update on it?
Furthermore, tried to put into scrollviewer but facing scrolling issue with it like:-
Scrolling with arrow keys wasn't working properly if i disable the internal scrollviewer of the record presenter of xam data grid and put it in the scrollviewer by setting the viewSetting to infinite
Moreover, for mouse scrolling to work properly i have to write an extra method in the code behind.
Your help will be greatly appreciated.
I never did get a response from Infragistics.
In the end I was able to work around the issue by disabling the two way binding and instead adding a ValueChanged event handler to the required columns to check whether the NewValue should be propagated to the datasource and then update the datasource if required. It's an ugly hack but in the absence of a solution from Infragistics it does at least work.
