We have a XamDataGrid contained within a MS Expander control.  The cells within the XamDataGrid are editable.

If the User collapses the expander, then re-expands it, the previously selected row for editing becomes disabled (cannot select, activate or edit) but other rows continue to be selectable and editable as before.  We must refresh the data source while the expander is expanded to work around this issue.

I have done a test where we removed the XamDataGrid from the Expander on the same page and it does not exhibit this behavior when NOT contained within an expander.

It appears to be an issue with XamDataGrid.  Has anyone seen this, know of a workaround?  Suggestions?

Thanks
